No. Name
[4] Fixing Pressure Roller
PS13 Fixing Pressure Release Sensor
Execution condition/timing
Engagement operation
• At power-on (*)
• At recovery from sleep mode (*)
• At warm-up rotation
• When the Fixing Pressure Roller is in a disengaged position at the start of a job
* Cannot be executed when the 24V interlock is disconnected due to reasons such as door being open.
Disengagement operation
Since this machine enters sleep mode without disengaging the Fixing Pressure Roller, the fixing pressure operation of the
roller can be skipped when the machine recovers, which shortens the startup time. Therefore, if the Power Switch is turned
OFF during sleep mode or the machine is left in sleep mode for a specified period of time, it is necessary to disengage the
Fixing Pressure Roller.
• When the Power Switch is OFF
• When the Power Switch is OFF during sleep mode
• When the machine is left in sleep mode for 4 hours
• When a power-on jam occurs
• At occurrence of a jam
• When the Right Door is opened and closed while the fixing disengagement operation cannot be executed because of
disconnection of the 24V interlock due to a door open jam
• When the machine is left in standby for 4 hours
Related error code
• E009-0000: Fixing engagement timeout error
• E009-0001: Fixing disengagement timeout error
Fixing Slight Rotation Function
Purpose
When the Fixing Pressure Roller and Fixing Film are continually engaged in the same position for a long time because the machine
has been left inactive for an extended period, the Fixing Film may become deformed. In order to prevent this problem, the Fixing
Pressure Roller and Fixing Film are rotated for a specified period of time when the machine has been left inactive.
Operation description
When the machine operates again after the specified period of time has elapsed since the last fixing operation, flying start control
is performed to drive the Fixing Pressure Roller and Fixing Film for the specified period of time.
Disengagement of the Fixing Film Unit is performed after drive is complete.
However, this control is only executed when the machine is in standby or in sleep mode. It is not executed when the power switch
is OFF, when an error has occurred, or when a jam has occurred.

Fixing Arch Control
Purpose
To prevent image failure/feed failure
Control description
The slack of the paper is kept at a specified level when the paper is fed from the Secondary Transfer Outer Roller to the Fixing
Pressure Roller.
Since the feeding speed of the Fixing Pressure Roller and that of the Secondary Transfer Outer Roller are not the same when
paper is fed to the Fixing Unit, image failure, paper wrinkle, image stretching, etc. occur.
