• When opening the copyboard cover or ADF, and also the detection temperature of the
main thermistor is less than 100 deg C.
• When the original sheet is set on the ADF tray, and also the detection temperature of
the main thermistor is less than 100 deg C.
• When the main power switch is turned ON or the machine condition is shift from the

Print temperature control
● Startup (warm-up rotation) temperature control
To increase fixing temperature to be ready for printing after receiving the print-start
command
● Print temperature control
To set optimal target temperature to prevent fixing failure or offset, and keep the specified
target temperature during printing
A.Setting target temperature
Target temperature is specified depending on the paper type, paper size, elapsed time
since the last control (including the standby control) of fixing temperature and fixing
temperature at the start of warm-up control.
B.Temperature control during printing
When the paper passes in the fixing unit, the fixing temperature is controlled to keep
the target value (see the table on the next page) according to the detection result of
main thermistor.
