Pickup Block

■
Pickup Control
The pickup block picks up sheets from the deck one by one and feeds them to the feed block.
The papers set in the deck is held up by the lifter, and is kept to a specific paper pickup
position.
When the Start key on the host machine is pressed, the deck pickup clutch (CL101, CL201,
CL301) goes on in response, the drive of the deck pickup motor (M001) starts to rotate the
pickup roller to pick up paper. At this time, the deck pickup/feed roller and the deck separation
roller operate to make sure that only a single sheet of paper is
picked up and moved. Thereafter, when the deck pickup sensor (S101, S201, S301) detects
paper, the deck pickup roller release solenoid (SL101, SL201, SL301) goes on to move the
deck pickup roller away from the stack of paper. Then, paper runs against the deck pull-out
roller to form a loop, thus correcting skewing of paper. When the deck pull-out clutch (CL102,
CL202, CL302) turns on after correction of paper skewing, the deck pickup motor (M001)
drives the deck pull-out roller to deliver paper to the feed unit.
