Auxiliary Tray Lift Control - Canon Finisher-AB1 Service Manual

3.3.3 Auxiliary Tray Lift Control

In response to an increase in the number of folded sheets in the tray, the auxiliary tray is moved up to prevent a
delivery jam associated with the tray B (memo) by making sure that the lead and trail edges of the stacks
deposited in the tray will be even.
The auxiliary tray is moved by operating the solenoid (SL9) according to the instructions from the finisher
controller PCB.

Tray B
MEMO:
A stack with a folded sheet tends to be higher along its lead edge than its trail edge, blocking the discharge slot
when it contains multiple folded sheets. (A subsequent sheet will likely hit the preceding sheet, causing a jam.)
