PRINTING
3. Paper Feed Mechanism (Optional Feed Unit)
Paper Feed Sequence
The paper feed sequence for the optional paper feed unit (PFU) is the same
as the standard tray except for the following:
•
The paper pick-up roller of the PFU is driven by the machine's main
motor.
•
The bottom plate [B] is lifted up when the release button [C] is pressed.
•
A corner separator [D] is used.
Jam Detection: Registration
Misfeed:
The machine detects a misfeed if the registration sensor does not turn on
within 2 seconds (4 seconds for the optional tray) after the paper pick-up
solenoid is turned on. A misfeed is also detected if the registration sensor
turns on before the paper pick-up solenoid is turned on.
When a misfeed is detected, the machine will finish printing that page before
turning off the drive components (error code 9-07 when the paper is fed from
the standard tray, or 9-50 when the paper is fed from the paper feed unit).
Paper Jam:
The machine detects a paper jam if the registration sensor is on when the
power is turned on or when the upper cover is closed. A jam is also detected
if the registration sensor remains on for over 11 seconds. When a jam is
detected, it immediately turns off all drive components, except the fusing unit
fan.
