    6. Detailed Section Descriptions Models with Duplex (G167: Printer model, G183/G184 MF model) For models with duplex, the transport/fusing motor drives the hot roller (same as the models without duplex). However, the paper exit roller [A] is controlled by the duplex motor [B]. This is because the duplex motor controls paper exit and feed in the duplex.

    Fusing and Exit Temperature Control The fusing unit has these components for temperature control: • The fusing thermistors [A] [B] send a signal when the fusing temperature goes past the threshold. • The central thermistor [A] is the one that is used for fusing temperature control. •...

    Fusing and Exit Anti-Humidity Mode To reduce paper curl in high temperature and humidity environments, the fusing unit does idle rotation before a job, if the customer enables this function in the user mode. • Mode 1: No fusing idling, transfer roller voltage is increased •...

    After the original set sensor has detected an original and the machine has got a copying or scanning job, the ADF motor rotates to pick up and feed a sheet of the original to the feed sensor. If the feed sensor does not detect paper after this sequence, the machine determines an original jam has occurred.
