Device status
Fixing temperature
C. Standby temperature control
Standby temperature control is applied as follows, when specified in service mode.
Standby temperature control begins once the temperature adjustment after job completion has finished, and continues for up to 15 minutes (but will stop once a
flying start instruction is received). The temperature is adjusted (between 160 deg C and 190 deg C), according to the time elapsed since the previous job finished.
Also, the fixer motor is rotated a prescribed number of times at 1 minute intervals.
The purpose of this function is to reduce the time required for the first print by adjusting the temperature.
service modes:
COPIER>OPTION>BODY>FX-ASTBY
Standby temperature control ON/OFF 0: OFF (default) 1: ON
To increase the time till 1st sheet print, set to [1].

Temperature control during printing regulates temperature from the beginning of the print cycle and until completion. The temperature of the target changes de-
pending on the material kind and the elapsed time and the number of sheets from the print beginning.
The temperature sequence is divided into the following 3 intervals:
- start-up (initial rotation) temperature control
- printing temperature control
- sheet-to-sheet temperature control
A. Start-Up (initial rotation) Temperature Controller
This control has aimed to select an energizing ratio the best so as not to exceed the maximum electric power consumption, and to start up the established machine
up to the temperature of the target in the regulation time.
B. Print Temperature Control
Print temperature control regulates temperature based on the number of sheets printed, paper type and main thermistor output upon activation of start-up control
during continuous printing in order to achieve a target temperature within the prescribed temperature range.
