Transfer Unit Motor

The Transfer Unit motor turns clockwise driving the Transfer Unit belt. Inside the
Transfer Unit are four Transfer Rollers located just under each Imaging Unit drum.
When the Transfer Unit Motor and Imaging Unit Motors are activated, they carry the
paper on the transfer belt to the Fuser. The voltages applied to the Transfer Rollers
attract the toner image from the Imaging Unit drum to the media.
