Light areas and voids on 11x17 trail edge, second side of duplexed copies only.


[Description]





Light areas and voids on 11x17 trail edge, second side of duplexed copies only.








[Solution]









CAUSE : The paper reverse/exit section has dislodged or become loose due to the exit mount plate mount screws loosen. This causes inconsistent pressure and causes excessive loop as the 11x17 enters the ADU section and causes the excessive loop to create the light or void areas on the second side of copies.

SOLUTION: Tighten the the exit plate mount screws and apply a drop of thread lock to prevent reoccurrence.

[Solution]











Engineering specifications allow for up to 15 mm of possible unacceptable density on the second side lead and trail edges of an 11x17 inch copy or print. The extent of image loss will depend on paper type, weight, and moisture content. To minimize image loss, the following should be checked and set to specification as outlined in the service manual:

1. Run 11x17 1:2 sky shot (black copy) and copies of test charts for reference.
2. Enter the 36 mode and select Image adjustment.
3. Select #2 (magnification adjustment).
4. Perform Printer drum clock adjustment 1:1 mode and 1:2 mode.
5. Perform printer horizontal adjustment 1:1 mode and 1:2 mode.
6. Perform scanner drum clock 1:1 mode and 1:2 mode.
7. From the image adjustment screen select #3 (Timing adjustments).
8. Perform printer restart adjustment 1:1 mode and 1:2 mode.
9. Perform printer lead edge timing adjustment 1:1 and 1:2 mode.
10. Perform scanner restart adjustment 1:1 and 1:2 mode.
Note: When performing these adjustments, when in 1:2 mode, only the second side is adjusted.
