Operation of the Paper Holding Lever
The paper holding lever is found to the side of the stack tray paper height sensor. The paper
holding lever is designed to prevent wrong detection of the height of paper otherwise caused by
curling of paper.
The paper holding lever is driven by the stack tray lift motor (M5), and it operates as follows:
When a stack of sheets is delivered to the stack tray, the stack is deposited on the paper holding
arm.
When sheets have been put onto a stack, the stack tray moves down until the stack tray paper
height sensor (S10) turns off, and then stops.
At this time, the paper holding lever moves inside the finisher, leaving the stack of sheets.
The stack tray then moves 12.5 mm from the point at which the stack tray paper height sensor
(S10) has detected the top of paper.
At this time, the paper holding lever which has been inside the finisher moves out to the top of
the stack to hold down the stack against the stack tray.
The above operations are repeated to keep sheets in place.
