Fusing drive release mechanism
• The fusing drive release gear transmits the driving force of the fusing motor to the fusing
unit and transfer belt retraction mechanism.
• When the right door is opened, the fusing drive release lever locked by the registration
unit is unlocked.
• When the fusing drive release lever is unlocked, the connection of the fusing drive
release gear is disengaged, so that drive connection to the fusing roller in the fusing unit
is also disengaged.
• If a paper misfeed occurs in the fusing section, opening the right door will disengage the
drive connection of the fusing roller. Thus, the jammed paper can be pulled out easily
with a light force.
• For details of the fusing mechanism, see "Fusing section".
