This release mechanism prevents deformation of the drum and the pressure
roller when the drum is pulled out to remove 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. This print pressure is released when the drum rotates to the drum
home position after the drum rotation button is pressed.
This printing pressure release mechanism works even if the paper detecting
feeler is actuated by the misfed paper.
