Description of Operations

The back side printing (recording data of the back side of paper) is performed first by selecting duplex
printing mode.
When the paper passed the reverse sensor, the reverse gate solenoid switches the reverse gate, and
the reverse roller switchbacks to transport the paper into the ADU.
The switchbacked paper is transported with acceleration. The transportation decelerates in front of the
ADU exit sensor. The front side printing (recording data of the front side of paper) is performed at the
registration section. The paper passes through the lower exit roller and is transported to the inner tray
to complete duplex printing.
There are three methods of judging a paper jam: (1) whether the ADU entrance sensor is turned ON or
not in a specified period of time after the switchback to the ADU started (E510). (2) whether the ADU
exit sensor is turned ON or not in a specified period of time after the ADU entrance sensor is turned ON
(E520). (3) whether the registration sensor is turned ON or not in a specified period of time after the
paper feeding from the ADU to the equipment (E110).
If the ADU is opened during duplex printing, the ADU motor is stopped, namely, ADU open jam occurs
(E430).
The equipment never stops during printing by interruption in any case except paper jam or service call.
