ROLL ASSY FEED (tray 2)
ROLL ASSY FEED (tray 3)
When the SOLENOID FEED operates, the GEAR FEED and GEAR IDLER FEED are engaged by the
force of the SPRING FEED, the ROLL ASSY FEED starts rotating under the drive from the DRIVE
ASSY FEEDER, and the ROLL ASSY feeds paper from the paper tray.
After rotating one turn, the GEAR FEED and GEAR IDLER FEED are disengaged at the notch of the
GEAR FEED cutting off the transmission of drive and stopping the rotation of the ROLL ASSY FEED.
Thus the sheets of paper are fed one by one.
ROLL ASSY TURN (tray 2)
ROLL ASSY TURN (tray 3)
The ROLL ASSY TURN is rotated by the CLUTCH ASSY TURN under the drive from the DRIVE ASSY
FEEDER and feeds the paper from the paper tray toward to tray 1.
