16.3 Operation
16.3.1 Up/down control
A. Up/down operation
• When the Tray1 Paper pick-up solenoid (SD1) is energized, drive from the Main 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.

16.3.2 Paper feed control
A. Pick-up/separation control
• When the Tray 1 media feed solenoid (SD1) is energized, drive from the Transport motor
(M1) is transmitted to the pick-up roller via the paper pick-up clutch and the pick-up roller
is rotated.
16.3.3 Double feed prevention mechanism
• The fixed separation pad system plus the claw stoppers are used for media separation.
This ensures that only the first sheet of media is taken up and fed in.
16.3.4 Remaining media detection control
A. Media empty detection
• The machine is not provided with any paper empty sensor.
• A media empty/misfeed condition is detected if the Registration sensor is not activated
after the lapse of a predetermined period of time after a media feed sequence is started.
