4. TROUBLESHOOTING

4.1 SERVICE CALL CONDITIONS

4.1.1 SUMMARY

There are 4 levels of service call conditions.

Level Definition Reset Procedure

A

To prevent damage to the machine, the mainmachine cannot be operated until the SC hasbeen reset by a service representative (see thenote below).

Enter SP mode, and then turnthe main power switch off andon.

B

SCs that disable only the features that use thedefective item. Although these SCs are notshown to the user under normal conditions,

they are displayed on the operation panel onlywhen the defective feature is selected.

Turn the operation switch ormain switch off and on.

CThe SC history is updated. The machine can beoperated as usual.

The SC will not be displayed.Only the SC history is updated.

DTurning the main switch off then on resets SCsdisplayed on the operation panel. These are re-displayed if the error occurs again.

Turn the operation switch offand on.

When a Level “D” SC code occurs

When a Level D SC occurs, a screen opens on the operation panel to tell theoperator:

• An error occurred

• The job in progress will be erased

• The machine will reboot automatically after approximately 30 seconds.

The operator can wait until the machine reboots automatically or touch “Reset” onthe screen to reset the machine immediately and go back to the copy screen.

If the operator does not touch “Reset”

The next message tells the operator that the machine will reset automatically andthat the previous job was lost and must be started again. After reading themessage, the operator touches “Confirm” on the screen. The next screen showsthe number and title of the SC code, and stops until the operator turns the machine

off and on.

If the operator touches “Reset”

If the operator touches "Reset" to bypass the 30-second interval for the machine toreboot, the machine reboots immediately and the operation panel displays the copyscreen.

Important

• Do not try to use the operation panel during an automatic reboot.

• If the Remote Service System is in use, the SC code is sent immediately to theService Center

4.1.2 SC CODE DESCRIPTIONS

Important

• If a problem concerns a circuit board, disconnect and reconnect the connectorsand then test the machine. Often a loose or disconnected harness is the causeof the problem. Always do this before you decide to replace the PCB.

• If a motor lock error occurs, check the mechanical load before you decide toreplace the motor or sensors.

• When a Level “A” or “B” SC occurs while in an SP mode, the machine cannotdisplay the SC number. If this occurs, check the SC number after leaving the SPmode.

• The machine reboots automatically when the machine issues a Level “D” SCcode. This is done for Level “D” SC codes only.

CAUTION Never turn off the main power switch when the power LED is lit or flashing.To avoid damaging the hard disk or memory, press the operation switch toswitch the power off, wait for the power LED to go off, and then switch themain power switch off.

NOTE: The main power LED ( ) lights or flashes while the platen cover or ARDF is open, while the main machine is communicating with a facsimileor the network server, or while the machine is accessing the hard disk ormemory for reading or writing data.

Recovery from SC 925

Procedure 1

If the machine shows SC codes for HDD errors (SC860 ~ SC865) with SC 925, do

the recovery procedures for SC860 ~ SC865.Procedure 2

If the machine does not show one of the five HDD errors (SC860 ~ SC865), turnthe machine power off and on. If this is not the solution for the problem, theninitialize the NetFile partition on the HDD with SP5832-011 (HDD Formatting –Ridoc I/F).

NetFiles: Jobs printed from the document server using a PC and DeskTopBinder

• Before you initialize the NetFile partition on the HDD, tell the customer that:

• Received faxes on the delivery server will be erased

• All captured documents will be erased

• DeskTopBinder/Print Job Manager/Desk Top Editor job history will be erased

• Documents on the document server, and scanned documents, will not be erased.

• The first time that the network gets access to the machine, the managementinformation must be configured again (this will use a lot of time).

Before you initialize the Netfile partition with SP5832-011, do these steps:

1. Go into the User Tools mode and do “Delivery Settings” to print all received faxdocuments that are scheduled for delivery. Then erase them.

2. In the User Tools mode, do Document Management> Batch Delete TransferDocuments.

3. Do SP5832-011, then turn the machine power off and on.

Procedure 3

If “Procedure 2” is not the solution for the problem, do SP5832-001 (HDDFormatting – All), then turn the machine power off and on.

SP5832-001 erases all document and address book data on the hard disks. Askthe customer before you do this SP code.

Procedure 4If “Procedure 3” is not the solution for the problem, replace the HDD.

The software performs anunexpected function. However,unlike SC990, recovery processingallows the program to continue.

• Software defective, re-boot*1

*1: In order to get more details about SC990 and SC991:

1) Execute SP7403 or print an SMC Report (SP5990) to read the history of the 10 most recentlogged errors.

2) If you press the zero key on the operation panel with the SP selection menu displayed, youwill see detailed information about the recently logged SC990 or SC991, including thesoftware file name, line number, and so on. 1) is the recommended method, because

another SC could write over the information for the previous SC.

Software error 3: Undefined992 D

An error not controlled by thesystem occurred (the error does notcome under any other SC code).


• Turn the machine power off and on. Themachine cannot be used until this error iscorrected.

• Loss of power during downloading

• Important Notes About SC999

• Primarily intended for operating in the download mode, logging is not performedwith SC999.

Note: If the machine loses power while downloading, or if for some other reasonthe download does not end normally, this could damage the controller board or the

PCB targeted for the download and prevent subsequent downloading. If thisproblem occurs, the damaged PCB must be replaced.
