■ Print Temperature Control

● Startup (initial rotation) Temperature Control
A fixing temperature is increased to a printable temperature after receiving a command to
start printing.
2
Technical Explanation > Fixing System > Controls > Print Temperature Control
● Print Temperature Control
To set optimal target temperature to prevent fixing failure or offset, and keep the specified
target temperature during printing
A. Setting the target temperature
A target temperature is determined according to the paper type/size, time which
elapsed from when fixing temperature control (including standby control) finished the
last time, and fixing temperature when startup control started.
B. Temperature control during printing
When the paper passes through the Fixing Assembly, temperature is controlled to
keep the target temperature (see the next page) according to the detected temperature
of the Main Thermistor.
C. Paper interval temperature control
A paper interval temperature is decreased to prevent temperature increase when the
paper interval became wider than a normal condition during the down sequence (*1).
Paper Interval Temperature = Target temperature during printing - (0 to 20 deg C)*2
*1: At down sequence
• The interval between the first side and the second side at 2-sided printing
• At execution of various controls (ATR control, registration control, and ATVC
F-2-109
control)
• At continuous printing of small size paper (smaller than A4R and LTR in width
direction)
• When the target temperature cannot be maintained due to low power
• When the Sub Thermistor detects abnormally high temperature even for A4R
size or larger
*2: The fixing temperature is determined depending on the elapsed time since the time
paper has passed through the fixing nip.
