1-1. DESCRIPTION.
SECTION I
GENERAL DESCRIPTION
Section I
The Hewlett-Packard Model 562A Digital Recorder is a transistorized electroIT!echanical device providing a printed record of digital inforrnation. Paralleldata entry and low-inertia moving parts allow printing rates as high as 5 linesper second, each line containing up to 11 digits; 12 digit capacity is availableon special order.
Throughout this nlanual the Model 562A will be referred to as the recorder.
1-2. DATA ENTRY.
Standard input for the recorder is parallel-entry 4-line BCD code, either 1224or 1248. Input to the recorder is through rear-l1'.lounted connectors. Internalconnectors route the inforn1ation to any desired sequence of columns. Eachcolumn has binary storage for one decimal nunlber.
When a print COITlmand is supplied, each storage unit assumes the condition ofthe decade counting unit (or other driving source) connected to it. The datatransfer takes place in approximately 2 milliseconds, after which tinle thed riving source is free to gather more infornlation.
1-3 . STANDARD INSTRUMENT.
Each storage unit is mounted on a plug-in board (column board) with a de-codingmatrix. The nlatrix converts the stored data into positioning inforIT!ation forthe print wheels. The recorder is supplied to translate 1224 BCD codes, butother 4-line codes are accoIYlmodated by substituting plug-in boards. Unlessotherwise specified, the recorder is supplied from the factory with the following:
a. Six +1224 coluIYln boards.
b. Printer nlechanism, 11 print wheels and associated components, fiveprints/second with 60 cps power line frequency.
c. One input connector at rear of recorder JI01.
d. One input cable.
e. One control board.
f. One power supply board.
01081-1 1-1
Section I
1-4. OPTIONS AVAILABLE.
The following options are available:
a. + or -1224 column boards.
b. + or -1248 column boards.
c. Analog circuitry.
d. Pinion gear, allows 5 prints per second with 50 cps power.
Model 562A
e. Input connector (J201) and associated connectors (for dual input operationor over 9 -column capacity).
f. Data input cable.
1-5. POWER REQUIREMENTS.
The recorder has been designed to operate frorr! 115/230 volt, 50/60 cps power.A switch, located at the rear of the recorder selects operation for either 115 or230 volts.
The three-conductor power cable supplied with the instrument is terminated ina three-prong polarized male connector recommended by the Electrical Manufacturers' Association (NEMA). The third contact is an offset round pin, addedto a standard two-blade ac plug which grounds the recorder chassis when usedwith the proper receptacle. An adapter should be used to connect the NEMAplug to a standard two-contact receptacle. When the adapter is used, the groundconnector becomes a short green lead. The green lead should be connected toa suitable ground for protection of the operating personnel.
1-6. USES.
Because of the extreme flexibility of the recorder, it can be used with electroniccounters, digital voltmeters etc. or a wide variety of individual and systemapplications. The recorder will operate with + or -1224, + or -1228 BCD, and10 -line code information depending on column boa rd s installed. Two separatesources, unsynchronized, can be used to provide data if option e is installed.The recorder supplies the synchronization. When the analog circuitry, option c,is installed, the operator may select analog voltage of columns 1 through 9 in3 -column groups.

INSTALLATION
2-1. GENERAL INFORMATION.
Section II
Section II contains information relating to installation and input connections.
2-2. RACK MOUNTING.
If the recorder is to be rack mounted, be certain to allow sufficient open spacefor cooling air to enter and exhaust. Do not rnount the recorder next to equipment which will discharge hot air into the recorder air intake.
2-3. CONNECTION TO THE $p TRANSISTORIZED COUNTERS.
The recorder may be directly connected to the ~ transistorized counters bymeans of the input cable supplied with the recorder. The transistorizedcounters have the correct connector installed. Recorder connector J101 isconnected to the counter recorder connector. If a second transistorizedcounter is to be connected to the recorder, connection is made froIn the secondcounter to recorder connector, J201. The transistorized counter output is+1224 BCD.
2-4. CONNECTION TO rfiJ COUNTERS AND DIGITAL VOLTMETER.
If the recorder is to be connected to the above tube type instruments a modification kit can be installed. The kit provides a +1224 BCD output.
2-5. OPERATION FROM TWO DATA SOURCES.
The recorder can be operated fronl two data sources, synchronized or unsynchronized, by connecting the data inputs to connectors J101 and J201. The twodata inputs can be ±1224 or ±1248 code. The appropriate coluInn boards Inustbe installed in the proper connectors in the recorder.
2-6. CABLE FABRICATION.
Connection of the recorder to data sources other than the above Inay requireconstruction of a cable terminated with a connector that will mate with therecorder connectors. Use small gage telephone-type wire. Number 26 gagewire meeting MIL-B -76A, with 7 strands #34 gage wire, tinned after stranding,with 10 SoC plastic insulation has been found satisfactory. Select a sy stematiccolor code for wires to avoid errors. Use care in soldering. Repairing faultyconnections after all wires are soldered is very difficult. A length of # 14 gage
wire makes an excellent soldering tip for use on closely-spaced connector terrninals.

SECTION III
OPERATION
3-1. OPERATING CONTROLS.
The operating controls consist of the following:
POWER ON,supplies power to the recorder when in the ON position.
Section III
RECORD ON,allows the printer mechanism to operate when in the ON position. When theswitch is in the spring-loaded position(down), the recorder prints at maximumrate. The middle p osition is a standby position(allows analog to be taken).
SPACE SELECTOR,selects the number of spaces between readout prints.
PAPER ADVANCE,manually advances paper.
ANALOG CONTROLS,(optional) refer to text.
3-2. PAPER TAPE.
Special ~folded tape is recommended for use with the recorder. High-qualitystandard 3 -inch rolled adding machine type may also be used.
Folded tape permits convenient take -up in the paper drawer and allows easyinspection of any portion of the type. It is perforated at each fold to allow neatseparation of portions of recorded data. Folded tape may be reversed and rerun to use both sides. With single spacing, about 15, 000 prints can be madeon one side of a folded pad. One pad will last about 40 minutes at maximumprint rate.
To install the paper tape proceed as follows:
a. Open front panel.
b. Load paper in compartment.
c. Fold paper back one inch and crease. Insert paper between roller andguide plate.
01081-1 3-1
Section III Model 562A
d. Manually advance paper. Paper will feed easier and can be reversed withSPACE SELECTOR set to "0".
e. Feed paper under inked ribbon.
f. Feed paper through slot. Close front panel.
g. Collect printed paper in drawer.
Follow these additional instructions if roll tape is used:
a. Insert spindle through roll. Spindle is taped to bottom of paper compartment when instrument is shipped from the factory.
b. Hang roll by ends of spindle from ledges on both sides of paper compartment.
c. Paper must feed out from the bottom of the roll.
d. Continue with loading.
To feed paper rapidly use the PAPER ADVANCE thumb wheel. To manually feedpaper backward, set the SPACE SELECTOR to "0" and roll the PAPER ADVANCEwheel in the reverse (up) direction. Paper feed may be reversed on!l. with theSPACE SELECTOR set to "0".
Be sure paper is inserted squarely in the paper feed mechanism to preventjamming. If paper doe s not feed smoothly, place the RE CORD switch in thecente r position, and re move all paper from the feed mechanism. Use tweezersto pick out torn bits of paper.
3-3. INKED RIBBON.
The printer mechanism uses a special heavily-inked silk ribbon available fromthe Hewlett-Packard Company. Standard typewriter ribbon on an Underwoodspool, with reversing rivets near the ribbon ends, may also be used; however,impressions will be lighter than with the Hewlett-Packard ribbon.
To install new ribbon, proceed as follows:
a. Open the hinged front panel to gain access to the printer mechanism.
b. Loosen the two printer mechanism retaining screws located on the lowerfront corners of the mechanism by turning 1/4 turn counterclockwise.
c .. Slide mechanism out of cabinet until ribbon spools are readily accessible.
d. Wind all the ribbon onto one spool.
3-2 01081-1
Model 562A Section III
01081-1
e. Shift the two ribbon spool retaining springs away from the spools, andremove spools.
f. Take the ribbon out of the mechanism. Save the empty spool.
g. Hook end of new ribbon on empty spool. Wind about 10 inches ofribbon on the spool so that the rever sing rivet is on the spool.
h. Install new ribbon by feeding it over the ribbon rollers and between theprint wheels and paper tape.
i. Feed ribbon through the slots in the reversing arms and around thelower guides. Ribbon must be twisted 900 between the ribbon roller and theslot in the rever sing arm.
j. Place ribbon spools on their shafts. Fasten spools in place with thespool retaining springs. Ribbon must feed out from the bottom of each spool.
k. Replace printer mechanism in cabinet and tighten retaining screws.
3-4. TAPE DUPLICATES.
Transparent paper, ~stock no. 9251-0052 is recommended for use in therecorder. This paper produces much less paper dust and copies can beeasily made with duplication machines. If duplicate tape records arerequired from standard paper, contact print duplicating methods, suchas the ozalid process, can be used by printing directly from the originaltape records.
3-5. PROGRAMMING THE RECORDER.
The recorder can be programmed to accept different codes if the propercolumn boards are installed. The column boards may be inter-mixed if desired.
The standard recorder is supplied with six +1224 BCD column boards, withconnectors installed to accept a total of nine column boards. If more thannine column operation is desired, J201 must be installed with the connectorsthat attach to the rear of the column boards (PIIO-PIl5).
Normally JIOl supplies data to column boards Al-A9, but connectors PIOlPI09 can be connected to supply data to any of the column boards the operatordesires. J201 can supply data to any of the remaining column boards. Connectors PIIO-Pll5 can be connected to supply data to six column boards.
3-6. PROGRAMMING THE CONTROL BOARD (AI3).
Connectors P20l and P202 supply control signals to the data sources, andreturn data source signals to the control board. Connector P20l is con-
3-3
Section III Model 562A
nected to one data source through JI01. and P202 to a second data sourcethrough J201. The control board senses when commands from both sourceshave been received, then starts the printing cycle. If only 'one data source isused, the control board connector that is not being used must be disconnected,otherwise the recorder will not operate but will wait until the control boarqreceives a second print command signal. When the control board connectorthat is not being used is disconnected, the associated print command binaryremains in the proper state of unbalance. Thus a print command is requiredfrom only one data source to start the printing cycle.
3-7. DATA SOURCE CONNECTIONS.
Data can be supplied continuously from two data sources. If six column readout is desired for one data source and five column readout is desired for thesecond data source, then one data source is connected to JI01 and the otherdata source to J201. The column board connectors can be connected as theoperator desires. Other combinations the operator may want can be had bychanging the connectors at the rear of the column boards.
3-8. PROGRAMMING THE COLUMN BOARDS.
The following tables are for 1224 and 1248 BCD code.

Section III
"1" and "0" levels (BCD input)
1) In a +1224 code, the" 1" level is positive with respect to the "0" level.
2) In a -1224 code, the" 1" level is negative with respect to the "0" level.The + or - prefix is deterrnined by the polarity of the" 1" level with respectto the "0" level.
3-9. REFERENCE VOLTAGES.
Input to the binaries is through gates which are controlled by two dc -biasingsignals which control the passage of transfer pulses. One of the biasing signalsis the BCD data input and the other is a reference voltage. The transfer pulsesare internally-generated within the recorder. The inputs to the binaries arecapacitively-coupled and may be floating with respect to chassis ground. Thereference voltage is thus required to establish a point to which the BCD sig'nalis referred. Two reference voltages are required in the data storage systemand should generally be the steady dc values of the 0 and 1 states of the BCDinput signal. This relationship of reference to BCD signal is shown in figure3-1 for a negative-going signal equal to the 1 level.

Section III
3-10. REFERENCE VOLTAGE ADJUSTMENT.
Model 562A
The input voltage applied for any column board must not exceed 150 volts. Thatis the refe renee voltage plus the B CD It 1It level should not be greater than 150 volts.For instance, if the BCD swing is from 100 volts (tiD" level) to 160 volts (til" level)then attenuation must be introduced to reduce the "0" level to 94 volts and the"1" level to 150 volts. The minus reference voltage can then be adjusted for94 volts. The plus reference level must then be adjusted to 150 volts.
Before a reference voltage can be chosen, the "0" and" I" levels of the equipment supplying the BCD signals must be known. For instance if the recorderis connected to a binary counter with a -1248 code, each column board will bedriven by a decade in the counter. Sometimes binaries in the decades havedifferent" 1" and" 0" levels, thus a proper reference voltage must be chosen.If the column board is a -1248 code, then the -reference voltage must be chosenthat includes the "1" levels applied to the A, B, C, and D binaries. A +referencevoltage must be chosen that will include the "0" levels for the A, B, C, andD binaries.
If high impedance reference levels are used (above 5000 ohms), suitable bypassing, providing a time constant of 150 ~s, should be used. If the BCD driveis derived from an unregulated supply, then it is desirable to obtain the referencevoltage from the same unregulated supply.
3-11. POWER SUPPLY AND INTERNAL REFERENCE VOLTAGES.
The power supply board, A16, supplies the de voltages required by the recorder.The power supply also has provisions for providing reference voltages of -9 to+17 volts. The operator can select a value of resistors or breakdown diodesneeded to provide the proper reference voltages. Connectors P301 and P302(optional) supply the reference voltages to the column boards. When using anexternal reference voltage, connectors P30l and P302 must be disconnected fromthe power supply board if resistors are installed. Unless specified by thecustomer, resistors are not installed. The proper mounting holes are in thepower supply board and the operator can install the resistors or break-down diodes required to give the desired voltage.
3 -12. PRINTING A MINUS (- ).
The recorder will normally print a blank with no BCD input. If the operatorwishes to print a -(minus) for a 1224 code, in place of a blank, proceed as follows:In table 3-1 under the column headed "character to be printed", find -(minus).Under the "Binary Input" column, the - charac ter must have a "l" input forthe A and D binaries. If the column board is a +1224 code, then the externalvoltage applied to the A binary input must be at least 4 volts more positivethan the negative reference voltage. Since the D binary has a 11 I" supplied
3-6 01081-1
Model 562A Section III
01081-1
by the transfer pulse when the nOll level is not present, no external voltage isrequired for the D binary. A -1224 code req uire s the same voltage s but ofdiffe re nt polarity.
If the column board is a +1248 code, in table 3-2 find -(minus). Under the"Binary Input" column, the - character must have a "l" input for the A, B,and D binaries. An external voltage applied to the A binary must be at least4 volts more positive than the negative reference voltage. The Band D binariesdo not require an external voltage as the transfer pulse supplies the" 1" levelwhen "0" level is not present. A -1248 code requires the same externalvoltages, but of different polarity.
3-13. SETTING THE ANALOG CONTROLS (ortional).
The POTENTIOMETER RECORDER binding posts on the 562A are designedto operate potentiometer type (voltage operated) recorders having lOO-millivoltfull-scale sensitivity, and greater than 50K ohm input resistance. The 562Acan also drive recorders having other values of input sensitivity and resistanceby making minor addiqons or modification to the POTENTIOMETER RECORDER ANALOG OUTPUT.
To use the 562A on a potentiometer recorder, proceed as follows:
a. Set the COLUMN SELECTOR to include the three number columns tobe recorded gr aphically.
b. Connect the potentiometer recorder to the POTENTIOMETER RECORDERbinding pos ts on the 56 2A.
c. Set the OPERATE lever switch to the G8.LV. ZERO position (the GALV.ZERO control has no effect on the POTENTIOMETER RECORDER output) butdoes supply zero output at potentiometer jack.
d. Zero set the potentiometer recorder with its own controls.
e. Set the OPERATE lever switch to the CALIBRATE position.
f. Adjust the CALIBRATE control to obtain full-scale deflection of therecorder pen.
g. Repeat steps c, d, e, and f.
h. Set the OPERATE lever switch to OPERATE. The graphic recorderwill now plot the number columns indicated by the COLUMN SELECTOR.
3-14. RECORDING WITH GALVANOMETER GRAPHIC RECORDERS.
The GALVANOMETER RECORDER output jack on the 562A is designed tooperate galvanometer type (current operated) recorders having I-milliampere-
3-7
Section III Model 562A
3-8
full-scale se nsitivity and Ie s s than 5000 ohnlS input re sis tance. The 562A canalso drive recorders having other values of input sensitivity and resistance bymaking minor additions or modifications to the GALVANOMETER RECORDER
ANALOG OUTPUT.
To use the 562A with a galvanometer recorder, proceed as follows:
a. Before connecting the recorder to the 562A, deternline which three of thenumber columns are to be plotted. Then set the COLUMN SELECTOR to include these three number columns.
b. Zero set the galvanometer recorder with its own controls.
c. Connect the recorder to the GALVANOMETER RECORDER jack usinga standard, 1/4-inch diameter three-circuit phone plug. The positive recorderterminal is connected to the ring contact on the plug, and the negative terminalto the tip on the plug.
d. Set the OPERATE lever switch to the GALV. ZERO position.
e. If necessary, zero set the recorder with the GALV. ZERO set controlon the 562A.
f. Set the OPERATE lever switch to the CALIBRATE position.
g. Adjust the CALIBRA TE control to obtain full-scale deflection of therecorder pen.
h. Set the OPERATE lever switch to the OPERATE position. The recorderwill now plot the number columns indicated by the COLUMN SELECTOR.
3-15. USING GRAPHIC RECORDERS HAVING DIFFERENTINPUT SENSITIVITIES.
To use a potentiometer recorder having greater than specified voltage sensitivity, shunt the recorder with a value of resistance which results in full-scaledeflection of the recorder pen while the 562A is set to CALIBRATE and theCALIBRATE control is cente red.
Potentiometer recorders having less than 50K ohm input resistance may beused, but the POTENTIOMETER RECORDER output will than provide lessthan 100 millivolts for full-scale deflection. The internal resistance at thePOTENTIOMETER RECORDER output is approximately 2500 ohms and whenloaded with this value, provides only 50 millivolts for full scale deflection.If the potentiometer recorder has sufficient sensitivity to operate with thelower input level, no modification is required to use the recorder. However,as the external resistance on the POTENTIOMETER RECORDER binding postsis decreased, so is the range of the CALIBRATE control, until at sonle low
resistance it may be necessary to provide an external calibrating control

consisting of a potentiometer connected as a variable shunt for the signalwhich is fed to the graphic recorder.
If a potentiometer or galvanometer recorder is to be used which requiresslightly greater output voltage or current, it is possible to increase the562A ANALOG OUTPUT by changing the values of certain resistors inthe analog circ ufts.

SECTION IV
THEOR Y OF OPERATION
4-1. INTRODUCTION.
Section IV
Operation of the 562A is dependent upon a series of timing and reference voltages. The timing voltages are supplied by the control board (Al3). Referencevoltages can be supplied by the power supply (A14) or by an external source.The following paragraphs will describe the functions of various circuits in therecorder.
4-2. CONTROL BOARD OPERATION.
Operation of the recorder is dependent upon a series of timing voltagesdeveloped by the control board. Refer to the functional diagram, figure 5-2.Assume the data source initiates a print command. Print Command BinaryNumber 1 changes state and immediately supplies the data source with a disablevoltage. Assume Print Command Binary Number 2 has its input connectorarranged so only one print is required. The Print Scan Schmitt is in theproper state because the shutter is open. The Print Scan Schmitt applies theproper signal to the "And" Gate. The "And" Gate conducts and causes theClutch Binary to change state. The clutch solenoid starts to energize. Whenthe Clutch Binary changes state, a signal is applied to the Delay Multivi-brator (2MS). The output of the 2 ms delay multivibrator produces a reset pulsewhich is applied to the storage binaries. This removes stored information andsets the storage binaries in the proper state to receive new information. Theoutput of the 2 ms delay multivibrator is also applied to a 60 J-Ls delay multivibrator. The output of the 60 J-LS multivibrator is applied to the storage binarygate diodes by way of the + and - Transfer Amplifiers, then data transfer takesplace. The output of the 60 f.LS multivibrator is also applied to thePrint Command Binaries and resets them. While this action is occurring, theclutch solenoid is completing its pull-in cycle. When the clutch solenoid hasengaged the clutch, the clutch will remain engaged for one complete revolutionof the clutch assembly because of mechanical action. As the clutch assemblyrotates, the shutter closes, de-energizing the photo conductor. This causesthe schmitt to change state, initiating the scan signal. The scan signal thenresets the clutch binary and opens the Inhibit Gate circuits which can allow thepawl magnets to energize. When the brush senses the correct voltage, the pawlmagnets de -energize and lock the print wheels at the proper position. Then thecharacter is printed as the clutch assembly finishes its one revolution, disengages,and opens the shutter. The photo conductor is energized and the system is readyfor the next print command.

Section IV
4-3. GOLUMN BOARD OPERATION.
Model S62A
4-2
The following theory is for operation of a -1248 code column board. Assumea data source has initiated a print command, the AND GATE in the controlboard conducts, and the clutch solenoid starts to energize. A signal is thenapplied to the 2 MS DELA Y lY1ULTIVIBRA TOR by the clutch binary. After2 ms, the nlultivibrator applies a positive reset pulse to the column boards.The binaries reset as follows:
A BINARY: Q 101, on; 0102, off
B BINARY: a 103, off; 0104, on
G BINAR Y: a 105, on; a 106, off
D BINARY: Q 107, off; a 108, on
The data source is supplying bcd information to the four binarie s. Supposethe bcd information supplied is for the decimal number 8. According totable 3-1, "0" level information will be supplied to the G, B, and A binaries.The D binary will have "l" level information supplied. The "0" or "l'" do notchange the state of the binaries. The - and + transfer pulses cause the binariesto change state if the 1t0" or II lit levels needed are present. At the D binary,if the "1" level is pre sent GR 104 is forward biased and - transfer pulse will gothrough diode gate GR 104. Since a 107 is off, the D binary will change state,a107 on and a108 off.
The G binary has "0" level information applied to diode gate GRI03. A + transfer pulse is applied to GRI03. Since the "a" level information applied to GRI03is equal to the + reference voltage, the diode will pass the + transfer pulse.Thus QIOS is off and al06 is on.
The B binary has" 0" level information applied to diode gate GR 102. Since the"Olt level information is (at least 4 volts) more positive than the -referencevoltage, diode GRl02 is reverse biased and will not pass the - transfer pulse. Thebinary will not change state. Transis tor a 103 re mains off and a 104 re nlains on.
The A binary has "a" level information applied to diode gate GRIOI. The "0"level mllst be equal to the positive reference voltage. This causes GRlOI tobe forward biased and pass the + transfp.r pulse. The A binary changes state,QIOI off and QI02 on.
Three of the halves of the binaries that are "on" will return, through matrixresistors, to pin 11 of connectors XAl-l to XA12 -1. This is the line whichcorresponds to the decimal number 8. In this case, R161, R175, and Rl99return to the line for the decimal number 8. These resistors make the linefor the number 8 go to app roximately +15 volts. Diode gate G Rl a5 and G Rl Ohsense when the line gets to approximately +15 volts and cause amplifiers al09»a 110, and Q III to de -energize the pawl magnet. The pawl then locks the

print wheel at that position. The number is then printed. When the data sourceinitiates another print command, the scan signal occurs a short time later andcauses amplifiers 0109,0110, and 0111 to energize the pawl magnet if thedata input has changed. The print wheel rotates. The magnet remains energizeduntil diode CRI0S has +lS volts applied from the matrix.
4-4. ANALOG CIRCUITRY OPERATION.
Sinc e the column board s contain stored binary information, an analog functioncan be derived to drive a strip chart recorder. The analog circuitry providesthe following:
a. A graphic presentation whereby the trend of recorded data can be seen ata glance.
b. Three digits of analog information where full scale on the recorder maybe a few parts per million of the original printed reading.
c. A recording where an increasing numerical count is always an upwarddirection on the strip chart recording.
d. An analog recording which is always on scale.
To derive the analog voltage a switching arrrangement is used which utilIzesthe stored binary data from three consecutive columns of the printed data.Any three of the first nine columns may be used as well as the first two righthand digits.
The binary output data is weighted according to the code required by thestorage units. Four resistors are used to develop a staircase function fromthe four storage binaries. The four weighting resistors are in the ratio 4221.Refer to the analog circuitry schematic. Each of the three storage decadesthen produces a staircase function with a level proportional to the numericalvalue of its stored binary data.
The three staircase voltages are then mixed in proportion to their decadevalue or in the ratio of 1, 10, 100, to produce a single staircase function1000 part in amplitude. Each discrete step then represents. 10/0 of full scaleand for practical purposes is an analog function. This output voltage is thenattenuated and applied directly to a potentiometer type strip chart recorder.
The analog signal is also applied to an amplifier whose output can be used todrive a 1 rna type galvanometer recorder.
Diode clamps insure accurate voltage levels before mIXIng. Compensationelements maintain constant output over wide temperature extremes.

5-1. INTRODUCTION.
SECTION V
TROUBLESHOOTING
Section V
Section V contains information relating to symptom, trouble, and localizationof troubles which may occur in the recorder. Table 5-1 lists the symptom,then a possible cause. It must be remembered that troubles other than thoselisted could cause a malfunction. The table lists the most possible cause.
01081-1
Table 5-1.
Symptom
No printer action when onlyone data source is used
No printer action when twodata sources are used
All columns print incorrectcharacter
One particular column printsan incorrect character
Printer mechanism will notoperate
Incorrect analog voltage
Trouble shooting
Possible Cause
See that the unused connector at the rear ofthe control board (AI3) is disconnected.Make sure print command is proper polarity.
Check power supply voltages, check printcommand binarie s, check if both datasources are initiating print commands andof proper polarity.
Check power supply voltages, check thecontrol board for proper reset, transfer,and scan signals (listed in timing voltagetable). Make sure reference voltages arecorrect.
Check the column board as sociated with theparticular print wheel. Interchange columnboards" if operation is restored, trouble isin column board. Make sure referencevoltages to column board are correct.
Press the RECORD ON switch to the downposition. Recorder should print at maximumrate. 1£ not, check fuses and power supply.
Make sure recorder is zeroed. ChecktIl volt power supply on analog board.Check clamp diodes.

Section V
5-2. LOCALIZING THE TROUBLE.
Model 562A
5-2
When a trouble has been traced to a specific board, make voltagp. meas urements on base, emitter, and collector of transistors. On the column boardbinaries, transistors that are "turned on" will have approximately t15 voltson the collector, transistors that are "turned off" will have approximately-5 volts on the collectors. Binary tables 5-2 to 5-5 list the states of thecolumn board binary transistors for various numbers and inputs. Binaries inthe control board can be checked for switching action with a dc coupled oscilloscope. When a binary changes state, the dc coupled oscilloscope will show adefinite change of dc level. A vac uum tube voltme ter can be used also.Figure 5-1 shows the timing voltages and sequence. Resistance measurementsmade between various sockets and connectors may be helpful. For this, usethe wiring and power supply diagram.
5-3. SEMI-CONDUCTOR REPLACEMENT.
Table 5-3 lists the various transistors and diodes. When a commercialreplacement type is not listed, the semi-conductor should be ordered fromthe Hewlett Packard Company. When two rfiJ stock numbers are listed, thesecond number IS the correct replacement.
