5.5.2 Feeding in Duplex Mode

When fixing on the first side ends, the paper is moved to the duplex reversing assembly

through the delivery vertical path assembly configured by the delivery paper deflecting plate

driven by the delivery paper detecting plate solenoid (SL14).

Then, a specific period of time after the trailing edge of the paper has moved past the de-

livery vertical path sensor (PS32), the duplex reversing assembly inlet roller starts to rotate

in reverse, turning over the paper and moving it to the pre-duplexing feed assembly.

The pre-duplexing feed assembly transmits the drive of the waste toner feed motor (M2)

to each of the feeding rollers by way of the reversal drive clutch (CL16), thereby moving the

paper to the duplex unit.

When the paper is moved to the holding tray by the drive of the duplex feed motor (M19),

the feeder roller moves down to butt the paper against the re-pickup shutter.

At the appropriate timing, the re-pickup shutter solenoid (SL8) turns on to move up the

re-pickup shutter. Then, the re-pickup roller starts pickup for the second side. F02-505-03

and F02-505-04 provide outlines of how paper is moved in duplex mode.

If a fault occurs in the rotation of the duplex feed motor for some reason, the control

panel indicates 'E017' in response.
