The sheet pressure rollers [A] are released from the sheet feed rollers [B] in
the stand-by condition. In this condition, an original can be inserted until it hits
the entrance gate [C].
When an original is placed on the sheet-through table, the sheet-through
original sensor [D] is activated and the machine automatically goes into
moving original scan mode. When the Print Start key is pressed, the inverter
motor and the sheet feed clutch turn on to drive the sheet feed rollers. The
original is pushed to the sheet-through gate to remove skew. After a while,
the sheet-through gate solenoid [E] is energized. The sheet-through gate
moves down and the sheet pressure rollers are pushed against the sheet
feed roller to transport the original.
The inverter motor stops for a moment when the inverter registration sensor
[F] is activated.
