■ Print temperature control

This is a control to set an optimal target temperature to prevent fixing failure or hot offset. Temperature is controlled to maintain

the specified target temperature during printing.

Setting the target temperature

Determined according to the time which elapsed from when fixing temperature control (including standby control) finished

last time and the fixing temperature when startup control started.

Temperature control during printing

Temperature is controlled to maintain the target temperature according to the detected temperature of the Main Thermistor

(Fixing Heater (Center) and Fixing Film (Center)).

■ Paper interval temperature control

The paper interval temperature is decreased to prevent temperature increase when the paper interval becomes wider than a

normal condition

Paper Interval Temperature = Target temperature during printing - (4 to 18 deg C)
