Adjustment

1. Print-Drum Position-A Adjustment

Checks and adjustment

(1) Pull out the print drum and return it back after removing the master attached to it.
(2) Start the Test Mode, and run Test Mode No. 551 (Print Drum on Position A).
(3) Open the scanner table.
(4) Open the master disposal gate housing, press down the clamp open arm plate by hand, and check

that it slots smoothly into the groove in the position A.

(5) If it does not slot smoothly into the position-A compensator plate or if the print drum moves, run Test

Mode No. 581 (Print Drum Position-A Adjustment) to adjust position A for the print drum. (On the
setting procedure, refer to Chapter 18: Test Mode.)

(6) Repeat from step (2) until correct print drum position A is achieved.
