3. Paper Feed Operation
Paper feed operation can be performed if the tray is stationary at a
position where it can feed paper (with the upper limit sensor (LUD)
being ON) and there is paper in the tray.
position where it can feed paper (with the upper limit sensor (LUD)
being ON) and there is paper in the tray.
When paper feed takes place, the paper feed motor (LPFM), the
transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) operate with the following timings:

paper feed solenoid (LPFS) operate with the following timings:
When the transport clutch (LTRC) turns ON with the paper feed
motor (LPFM) is ON (rotating), the transport roller starts rotating.
When the paper feed clutch (LPFC) turns ON in this state, the
paper feed and paper pick up rollers start rotating.

paper in the tray when the tray is lifted and stopped at a position
where it can feed paper, as well as during paper feed operation.
