6.10.5 HOT ROLLER CLEANING
The cleaning roller [A] is diagonally
above the hot roller, and presses
slightly against the hot roller [B] to
maintain constant contact. It is coated
with material saturated with silicone oil.
To prevent the oil from streaking, at the
start of rotation, the hot roller reverses
briefly to wipe its surface against the
cleaning roller.
The hot roller and pressure roller [C]
both have stripping pawls.
6.10.6 HOT ROLLER THERMOFUSE
⇒
Non-contact thermofuses (rated
for 192 ° C [A] and 216 ° C [B])
near the hot roller [C] prevent
accidental overheating which
may lead to a fire hazard.
6.10.7 FUSING UNIT DRIVE MECHANISM
The fusing motor (a stepper motor) [A]
drives the fusing unit, the transport belt,
and the paper exit unit via one gear train
[B] and two timing belts [C].
