The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.

2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.

In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

LED lamp unitOn LED lamp unit, the light is generated from the 2 LED lamp PCBs (LED chip: 48 pieces per PCB).Generated light is exposed to the original through the reflection plate.

Free curvature mirrorScanner unit is equipped with the 3 folding mirrors and 4 free curvature mirrors.Free curvature mirror has symmetric facet in horizontal direction and asymmetric facet in vertical direction against the optical axis.

Reading sensorReading sensor scans the image per 1 image line.Reading sensor has 4 lines (R, G, B, BW). At B&W scanning, it uses 1 line (B/W) and uses 3 lines (R, G, B) at color scanning.

Adjustment Method

Adjusting the Height

Pre-checkCheck whether the front and rear document glass spacers provided under the bottom of the ADF are in close contact with the document glass when the ADF is closed.If visual check is difficult, perform the check with reference to the next and subsequent pages.

MEMO:Insert a sheet of paper between the ADF scan glass and the document glass spacers (two) and pull out the sheet in the direction of the arrow. It is recommended that slight resistance is felt when pulling out the sheet.

Caution:

Use plain paper.

Insert a sheet of paper in such a manner that the sheet material portion of the stream reading glass is concealed.

Checking the left hinge height

1) Checking the rear-left height of the ADF.

Set paper against the protrusions of the stream reading glass in such a manner that the seat of the stream reading glass is nearly hidden.

Caution:

Set paper so that it does not reach the document reader.

Adjustment Procedure(When the front or rear side is floating)

1) Adjust the left hinge height.2) Adjust the right hinge height.3) Adjust or check the left hinge height.

(When both sides are floating)1) Adjust the left hinge height.2) Adjust the right hinge height.3) Adjust the left hinge height.4) Adjust or check the right hinge height.

Adjust the height of the left hinge

1) Adjust the height with the left hinge height adjusting screw.

Caution:

Loosen the lock nut before adjustment, and tighten it after adjustment.

If the front spacer is floating, turn the adjusting screw clockwise to bring the spacer closer to the glass.If only the rear spacer or both front and rear spacers are floating, turn the adjusting screw counterclockwise to bring the rear spacer closer to the glass.

Check the height of the right hinge

1) When the ADF is closed, the document hold sheet must be in contact with the document glass.

Adjust the height of the right hinge

1) If the height is improper, adjust it with the right hinge adjusting screw.

Caution:

Loosen the lock nut before adjustment, and tighten it after adjustment.

Turning the adjusting screw clockwise reduces the front-right side height of the ADF.Turning the adjusting screw counter clockwise increases the front-right side height of the ADF.

2) Check the height of the left hinge. If the height is inappropriate, adjust it again.

Adjusting the Tray Width

MEMO:The result of this adjustment is retained on the reader controller PCB. As such, unlike previous ADFs, you will need to make this adjustment at time of installation so that you will be able to store its result in the reader unit. If you omit this adjustment, the following will likely occur:- wrong original size detection

Caution:

Adjust the tray width by performing either AB-configuration adjustment or inch-configuration adjustment.

AB-Configuration Adjustment

3) Adjust the tray side guide to the A4/A3 index.

4) Touch [OK] to register the A4 width.

5) Touch [TRY-A5R] to highlight.

6) Adjust the tray side guide to the A5R index.

7) Touch [OK] to register the A5R width.

8) Press the Reset key twice to end service mode.

3) Adjust the tray side guide to the LTR/11x17 index.

4) Press [OK] to register the LTR width.

5) Press [TRY-LTRR] to highlight

6) Adjust the tray side guide to the LGL/LTRR/STMT INDEX.

7) Touch [OK] to register the LTRR width.


Adjusting the Perpendicularity

1) Load a test chart in the ADF to make a copy.

MEMO:The test chart is printed on the back cover of the Installation Procedure (this manual). Copy it or clip it out.

2) Check the perpendicularity at the leading edges of the test chart and copy.

Measure dimensions A and B on the test chart and dimensions A' and B' on the copy. If it is not (A-B) = (A'-B'), go through steps 3) and later.

3) Press [STRD-POS] to highlight.

4) Touch [OK].

A press on [OK] will cause the scanner to start a scan; in several seconds,the machine will end auto adjustment of the read position and indicate 'OK'.

Caution:

If the machine fails auto adjustment and indicates 'NG', go through the following:
