Machine Details continued
Image transfer unit
•
Bias rollers located opposite the OPC drums transfer
toner from the drums to the transfer belt. Four toner
images are super-imposed onto the belt.
Paper transfer roller unit
•
The ITB drive roller pushes the toner from the transfer
belt to the paper (the transfer roller is an idle roller).
Fusing unit
•
This is a belt-type fusing unit. A heating roller, not in the
paper feed path, heats a belt. Then the belt in turn, heats
the hot roller. This type of unit warms up the rollers faster
than a conventional two-roller system.
