ADJ3. 2. 2 DADF Parallelism
Reference PL: PL18. 3
Purpose To correct the ADF front-to-rear position by adjusting the Right Counter Balance and to
solve problems such as skews.
Check
1. Remove the Front Cover. (PL18. 1)
2. Remove the Entrance Tray. (PL18. 1)
3. Remove the Document Transport. (Up to Step 2 of REP16. 10. 1)

Adjustment
Adjust only the Left Counter Balance basically. (This is because the DADF rigidity
causes the Right side to lift easily.)
After checking that the [Communication Lamp] is turned Off and that there are no
[Jobs in Progress] and [Printer Jobs in Queue (except the printer jobs during HDD
spooling)] on the [In Progress/Queue] screen, turn Off the Power Switch and
disconnect the Power Cord.
(Fig. 1) The measurement point must be at the center of the Right Counter Balance.
Thrust the scale against the DADF Rear Frame correctly
The front-to-rear position adjustment must be made within ±1 mm of the specified
range. Do not adjust more than that.
