[hknwbec]

Hi, I have a problem on IRC 3200 Feeder adjustment. Could you let me know how to fix it.
The problem is that, When using feeder to make enlagement A4 - A3, the copy come out does not in center position. As we dont have feeder service manual. How can we adjustment the feeder tray to normal position and control the copy come our in the center position. Thanks

- Place a single sheet (A3 or 11” x 17”) on the document tray and press OK. The document
is fed onto the copyboard glass and stops.
- Open the ADF and check the position of the document on the copyboard glass. Check
that the difference between L1 and L2, as illustrated below, is within 1mm.

If the gap is not within standard, loosen the nut at the back of the right hinge unit.
Use a 7mm diameter spanner to loosen the nut.

Rotate the (hexagonal) adjustment screw and adjust so that the L1 to L2 gap is less than
1mm.
(The adjustment screw should be rotated a maximum of two times.)
*: In this case, the ADF will not move by the rotation of the adjustment screw alone. One the screw has been rotated, move the ADF by hand.
After adjustment, tighten the nut and secure the adjustment screw.

Document tray width adjustment (A/B type, inch type)DF3.JPGSensor level adjustment (sensitivity adjustment)
This adjustment is to be carried out when replacing the ADF controller board, document
set sensor (U503), final document detection sensor (U504), pre-registration sensor (U502),
reverse outlet sensor (U505).
1) Stick an all black piece of paper over the final document detection sensor on the document tray.
Make sure the black paper is not over the document set sensor.
2) Close the ADF and enter service mode FEEDER > FUNCTION > SENS-INT.
3) Press ‘OK’.
While the automatic adjustment is being carried out, the display will read SERVICE in the upper right corner.
About 15 seconds later, the document detection LED will flash twice, the display will
change from SERVICE to READY. This means that the automatic adjustment is completed.
