ADU 15 - 6

15.3 Description of Operation

15.3.1 Paper stack operation

When the double-sided copy mode is selected on the copier’s control panel, and the COPY button is

pressed, the paper side guides and paper trailing end guide on the ADU stack section move to the

positions corresponding to the selected paper size by respective motor drive. At the same time, the ADU/

exit switching gate moves to the paper stack position by the gate solenoid.

The copied paper is fed inside the ADU inlet guide by the ADU/exit switching gate. During this operation,

the paper is detected by the reversal sensor, and ADU drive motor operates, the inlet roller rotates by the

ADU inlet roller forward rotation clutch, and the paper is fed further into the stack section.

When the paper enters the stack section, it is temporarily stacked on the holding gate receiving section,

and the paper is stacked between the pick-up roller and the holding gate as the holding gate rotates. At

the stack section, the paper is stacked with the copied side facing down. This operation is repeated until

the specified number of sheets of paper are stacked.

When paper stacking is started, the paper side guides open to make a gap of 1 mm on both sides of the

paper and are set at this position. Each time that five sheets of paper are stacked continuously during

stacking, the side guides align the sides of the paper.

The ADU empty switch is for detecting whether or not paper is on the stack section.
