Second and subsequent stacks
The second and subsequent stacks of paper are conveyed and stacked.
(1.) The first page has already stopped in the stacker entrance and the stacker
entrance roller stops to wait for the previous stack to be exited. The by-pass gate
is open at this time and the first page is in the lower region of the by-pass gate.
(2.) The by-pass gate is closed and the second page is stacked on top of the first.
(3.) Once the previous stack has exited, the stack entrance roller rotates and the first
and second pages are simultaneously sent to the stacker.
* The steps (1) to (3) above are for paper to a maximum of LT size.
(4.) The sponge roller of the stacker section sends the paper to the stopper and the
paper is lined up in the lengthwise direction.
(5.) The alignment plate unit lines up paper in the width wise direction.
(6.) When all paper is conveyed to the stacker, the paper is stapled.
(7.) The second and subsequent sets are conveyed by the paper exit arm and the
paper is exited to the shift tray.
