6.9.7 FUSING UNIT DRIVE MECHANISM

[G]
[F]
The fusing motor [A] (a stepper motor) controls the gears and timing belts [B] that
turn the hot roller [C]
The pressure of the hot roller against the pressure roller [D] and cleaning roller [E]
turns these rollers in the opposite direction.
An idle gear [F] turns the gears and timing belts [G]. These gears and belts turn the
fusing exit roller [H] and upper exit rollers [I] in the same direction as the hot roller.
The speed of the fusing motor is controlled by:
• The paper feed source set by the user (manual feed table, roll feeder paper
cassette).
• The type of paper (plain, recycled, translucent, film) set for the paper feed source.
(This is done with the User Tool
Tray Paper Type).
• The width of the paper in the feed source that is used. (The width in each feed
source is set with the User Tool
Paper Size. The feed source for the job is set at the operation panel.)
