<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.
Fusing Roller Temperature
Machine Condition
Less than 100°C 100°C or higher
Power is turned ON. Mode 2
Temperature control is interrupted during
warm-up.
Temperature control is interrupted during
mode 1.
Mode 1
Temperature control is interrupted during
mode 2.
Temperature control is interrupted during
mode 3.
Mode 1
Mode 2
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.
