<Adjustment procedure>
Notes:
• When the fuser belt was replaced with a new one, turn the gear by hand for 2 or 3 rotations
until the new belt works smoothly.
• When the fuser belt was not replaced, do not turn the belt before you start the gap
adjustment. When the fuser belt is heated and then cooled down, it has a slack where the
heat pipe roller rolls up the belt. When this slack is moved away from the heat pipe roller, it
makes the gap adjustment incorrect.
The slack of the fuser belt
is not on the heat pipe roller.
• If you turned the belt before the gap adjustment by mistake, follow the procedure below to
move the slack back to the position where the heat pipe roller rolls up the belt.
Loosen the pressure screw to remove the spring so that the pressure roller will not be
pressed. Then rotate the gear to turn the belt so that a heavy load is applied on the rotation of
the gear when the slack on the fuser belt passes over the heat pipe roller. At this time release
your hand so that the slack comes at the position where the heat pipe roller rolls up the belt. It
is easier when you check from the side if the slack has come at an appropriate position.
Load on the gear becomes heavier.
