6.9.7 FUSING UNIT DRIVE MECHANISM
The fusing motor [A] (a stepper motor) controls the gears and timing belt [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 belt [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, and
cassette).
! The type of paper set for the paper feed source: plain (not displayed), recycled,
translucent, or film, (This is done with the User Tool: System Settings > Paper Type
Settings > 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 1 System Setting > 1 General Features > Tray Paper Size.
The feed source for the job is set at the operation panel.)
