Up/down control
A. Up/down operation
• When the Tray1 Paper pick-up solenoid (SD1) is energized, drive from the Transport
motor (M1) is transmitted to the Pick-up roller via the Paper pick-up clutch. The Pick-up
roller is thereby rotated.
• At the same time, the Lift cam is rotated, which raises the media lift plate. This allows the
media to be taken up and fed in by the Pick-up roller.
