Controlling The Fixing Roller Drive; Controlling The Cleaning Web Drive - Canon imageRUNNER 7095 Service Manual

9.1.4 Controlling the Fixing Roller Drive

The machine controls the braking mechanism to present paper from fully wrapping around the fixing roll-
er.
In response to detection of an inside delivery delay jam, the machine causes the motor brake to go on to
stop the motor. This operation is executed exclusively in response to an inside delivery sensor delay jam.
ERROR CODE:
E014 (fixing motor speed error)
When the motor is rotating (i.e., FUSE_M_ON=1), FUSE_M_LOCK=1 is true for 2 sec or more.

9.1.5 Controlling the Cleaning Web Drive

Checking the Remaining Length [1]
When the web detecting flag comes into contact with the cut-off (300 mm from the end of the web),
the web length warning sensor (PS8) detects the flag, causing the machine to indicate a message
in the control panel (to the effect that the web is running out). The machine remains ready for making prints.
When '1', the motor brake goes on
When the motor rotation
speed is as specified, '0'
