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 menu settings: [Menu]> "Paper Input"> "Paper Type: Tray n (where "n" is 1, 2,
3, or "Bypass").
• The width of the paper in the feed source that is used. (This is done with the menu settings: [Menu]>
"Paper Input"> "Paper Size: Tray n (where "n" is 1, 2, 3, or "Bypass").
Wrinkle Prevention
Motor Speed Control
During normal operation, the hot roller [A] (controlled by the fusing motor) is slightly faster than the
registration rollers [B] (controlled by the main motor).
This stretches the paper between the registration rollers and the fusing unit to keep the paper from wrinkling
inside the fusing unit.
Inching Control
This machine also has an inching control feature that controls the temperature of the pressure roller to
prevent wrinkling. (See p.424 "Temperature Control".)
