<Temperature Control by Mode>
The mode that is initiated following the completion of a warm-up cycle varies as detailed below
depending on the machine condition and the Fusing Roller temperature at the restart of temperature
control.
Machine Condition
Power is turned ON.
Temperature control is interrupted during
warm-up.
Temperature control is interrupted during
mode 1.
Temperature control is interrupted during
mode 2.
Temperature control is interrupted during
mode 3.
2.4.15.4 CPM Control
As a measure to prevent the temperature on the edges of the Fusing Rollers (over which no part of
paper passes) from rising in a multi-copy cycle using small size paper (width of 250 mm or less), the
paper feed interval is made greater.
<Control>
If a sheet of small size paper is taken up and fed in during mode 1, control is switched to mode 2.
The number of sheets of small size paper that are fed through is counted.
<Timing>
The counter reaches 30.
The plain/special paper counter reaches N specified below:
If the control is in mode 1 or mode 2 when the counter starts counting, N = 30.
If the control is in mode 3 when the counter starts counting, N = 100.
<Resetting>
If a period of 2 min. or more elapses, during which the counter does not count up after the counter has
started counting, the counter is cleared resetting the CPM control.
Fusing Roller Temperature
