5.1.1 OVERVIEW

5.1.2 ON/OFF CONTROL
NOTE: The following explanation is for the 230V machine only.
To prevent the power supply from the inlet from fluctuating when the fusing lamp
turns on, this machine controls the fusing temperature as follows.
1. When the fusing lamp turns on, 35% of the ac power is applied to the lamp for
500 ms, then full ac power is applied. In the fusing lamp off condition, ac power
is reduced to 35% for 500 ms, then cut.
2. When not copying, the BCU keeps the fusing temperature at the appropriate
fusing temperature r 10q C.
This reduces the number of times the fusing lamp switches on/off.
