Theory of Operation
Transfer/ Fusing/ Paper Output
The belt (IBT Belt Unit) that rotates from the drive of the IBT Belt Drive Motor and
the 2nd BTR transfers the latent image from the belt onto the paper as it passes
through the Registration section. Next, the Heat Roll (Fuser Assembly) fuses the
latent image on the paper and transports the paper towards the Paper Output
section. At the Paper Output section, forward rotation (CW direction) of the Exit
Motor rotates the Exit Roll in the paper output direction. The completion of paper
output is detected by the Fuser Exit Sensor.
