Print Pressure Release Mechanism - Ricoh C226 Service Manual

PRINTING SECTION

6.3 PRINT PRESSURE RELEASE MECHANISM

[A]
The release mechanism prevents the deformation of the drum and the
pressure roller when the drum is pulled out of the machine to remove a
misfed paper.
The printing pressure solenoid [A] is energized/de-energized at the same
time as the paper feed solenoid.
When a paper misfeed occurs, the paper feed solenoid and the printing
pressure solenoid are de-energized but the print pressure is still applied to
the drum until the pressure solenoid mechanism is re-latched. The print
pressure is released (re-attached) when the drum rotates to the drum home
position after the drum rotation button is pressed.
This printing pressure release mechanism will work even if the paper
detecting feeler is actuated by the misfed paper.
