2.5.2.7 Automatic release of fixing pressure mechanism

LBP5000 / LBP5100
The machine is equipped with a mechanism that causes the fixing pressure roller and the fixing film to disengage for removal of jams.
When a jam occurs in the fixing assembly, the fixing film assembly is moved away from the fixing pressure roller. The state of engagement/disengagement is
checked by the shift sensor.
If the shift sensor indicates the state of engagement during printing and then fails to indicate the state when a jam has occurred, the DC controller PCB will identify
the condition as being a fault in the auto fixing assembly release mechanism and will indicate 'E840' in the status window.
