When the main switch turns on, the CPU checks the frequency of the power
(AC) for 500 ms; this is done in case phase control mode is selected later.
Then the CPU turns on the main fusing lamp. After 3 more seconds, the
secondary fusing lamp is turned on. This delay reduces the surge current
after the main switch is turned on.
Both lamps are turned on to raise the temperature of the hot roller’s surface.
When the thermistor detects the operating temperature (185
°
C), the copier
turns off the secondary fusing lamp, and starts fusing idling for 100 seconds
to warm up the hot roller completely and evenly (the roller has a thicker metal
core), and to distribute the oil. During fusing idling, the temperature is kept at
185
°
C.
When fusing idling is finished, the copier enters the ready condition. The CPU
keeps the temperature at 185
°
C by turning the main fusing lamp off and on.
The lamp is turned off at 190
°
C, and on at 180
°
C.
If the fusing lamp turns on while the exposure lamp is on, the power supplied
to the exposure lamp may fluctuate, possibly degrading the copy quality. To
prevent this, in this machine, the fusing lamp can either stay off or change
from on to off while the exposure lamp is on.
There are two types of fusing unit control: on/off control, and phase control.
The mode can be selected with SP1-104.
