Paper interval temperature control
A paper interval temperature is decreased to prevent temperature increase when the paper
interval became wider than a normal condition
*1
.
Paper Interval Temperature = Target temperature during printing - (15 to 30 deg C)
*2
*1:
At down sequence
• An interval between the first side and the second side at 2-sided printing
• At execution of controls (ATR control, registration control, ATVC control)
*2:
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.

Purpose:
Deterioration of the Fixing Offset and Fixing Film is prevented by controlling temperature
increase at a non paper feed area at continuous printing of small-size paper (paper with the
width direction size of less than LTR)
Startup condition:
Executed when the detection temperature by the Sub Thermistor 1 (TH3) or Sub Thermistor
2 (TH4) exceeded a specified temperature (235 to 270 deg C) during printing.
