Below are the cases in which pressure will be applied to the fixing film unit:
- When pressure is not applied at power-on state
- When pressure is applied at power-on state
- When returning from sleep mode
- After jam removal
- When the state of pressure application is not certain after opening / closing doors with interlocks such as front cover (E.g. when a door is opened while pressure
is being applied)
Below are the cases in which pressure will be released from the fixing film unit:
- In power ON jam at power-on state
- When paper jam has occurred
- When the equipment enters the sleep mode (both the soft switch and the timer are applicable)
The fixing motor (M3) will be rotated forward (the positive rotation) when pressure is applied. The fixing motor (M3) will be rotated in the opposite direction (the
negative rotation) when pressure is released.
The sensor flag [3] in conjunction with the pressure release cover [2] will be rotated, and the fixing automatic pressure release position sensor (PS13) will detect
the movement. This regulates the start / end timings of applying and releasing pressure.
Error code
Error in pressure/release of fixing film unit
In case that the output of fixing automatic pressure phase sensor is not changed although rotating/reversing the fixing motor
