[A] Fusing Exit Sensor [D] Pressure Roller
[B] Fusing Motor [E] Fusing Sleeve Belt
[C] Fusing Entrance Sensor
The fusing motor [B] drives the pressure roller [D] through gears.
The pressure roller [D] drives the fusing sleeve belt [E].
The fusing entrance sensor [C] and fusing exit sensor [A] detect paper jams around/in the fusing unit.
Fusing Temperature Control
Warm-up mode
When the main power switch is turned ON, the machine starts the fusing warm-up. The machine drives the
fusing motor to increase the fusing temperature to the reload target temperature. When the machine completes
the fusing warm-up, it keeps the reload target temperature by driving the fusing motor for a certain period of
time.
Standby mode
When a certain period of time passes after fusing reload is completed, the machine stops the fusing lamp and
fusing motor. Then the machine keeps the fusing temperature to the standby target temperature (SP1-107-001)
by energizing the fusing lamp.
In standby mode, the machine starts the fusing motor intermittently.
Printing ready mode
After returning to standby mode, the machine lights the fusing lamp to increase the fusing temperature to the
printing ready target temperature. If there is no printing job, the machine then moves back to the standby mode.
If there is a printing job, the machine starts the fusing lamp to increase the fusing temperature to the target
temperature after reload/feeding, and then starts the print job.
CPM Down Control
This machine automatically lowers the CPM according to usage and machine status to obtain the best image
quality and keep the machine in good condition.
If the fusing lamp is always activated during consecutive printing, and/or the paper size is smaller than the
lamp’s width, then some heat will not be used for fusing and may stay around the front and rear ends of the
fusing unit. This will increase the temperature in the fusing unit abnormally.
CPM down control keeps the machine’s CPM low until the fusing unit sufficiently cools down. Normally, it
takes 10 minutes to recover the original CPM.
