• Rotation of the heating roller results in the cylinder actuator being rotated.
• As the heating roller rotation sensor alternates between unblocked and blocked states at regular intervals, the machine determines that
the heating roller assy is rotating.
• If the heating roller rotation sensor remains unblocked or blocked for a predetermined period of time during printing, the machine
determines that a paper misfeed occurs at the exit, displaying a corresponding message on the control panel.
• If the heating roller rotation sensor remains unblocked or blocked for a predetermined period of time during a warm-up cycle, standby
state, or any other timing than a print cycle, the machine displays the malfunction code "C3102: Heating roller failure to turn" on the
control panel.

14.3.2 Fusing drive release mechanism
• At the fusing drive position, transmit the driving force of the fusing motor to the fusing pressure roller by a fusing drive release gear.
• Opening the right door places the fusing drive release lever in the fusing drive release position.
• With the fusing drive release lever in the fusing drive release position, the fusing drive release gear is disconnected from the fusing motor
and, instead, connected to the jam removal dial.
• If a paper misfeed occurs in the fusing section, opening the right door allows the jam removal dial to be used for removing the misfed
paper.
