AUTOMATIC DUPLEXING UNIT (ADU) (OPTION: MD-0103)
13 - 6
13.5 Description of Operation
The back side printing (recording data of the back side of paper) is performed first by selecting duplex
printing mode and pressing the [START] button. When the trailing edge of the paper passes the exit
gate, the paper is switchbacked by the exit roller and transported into the ADU.
The front side printing (recording data of the front side of paper) is performed at the registration section.
The paper passes through the exit gate again and is transported to the inner tray to complete duplex
printing.
The detection of paper jam is performed in two methods. In one method the paper jam is judged by
whether the ADU sensor is turned ON or not within a specified period of time after the paper started to
be switchbacked to the ADU (error code: E51), and in another method, it is judged by whether the
registration sensor (S4) is turned ON or not within a specified period of time after the paper started to
be fed out of the ADU to the equipment (error code: E11).
ADU open jam (error code: E43) occurs when the ADU is opened during the duplex printing and thus
the ADU motor is stopped.
The equipment is never to be stopped during printing by interruption in any case except paper jam or
service call.
The operation of the duplex printing differs depending on the size of the paper; single-paper circulation
and alternateness circulation. The figures in the following pages show the circulating operations during
duplex copying. The numbers in the figures indicate the page numbers.
