When a paper jam occurs downstream of the main machine, all the paper in the paper path of the main machine is immediately shunted into the purge unit. In the previous machine, paper exit was driven by only exit motor [A]. This machine, however, is equipped with the heat pipe motor [B] which also feeds paper to the exit. This additional motor ensures that paper will feed into the purge tray even if a downstream jam causes paper to jam in the exit and stop the exit motor.
A knob can be rotated manually from the front to make paper jam removal easier. This knob is new. At least two full turns are required to remove long paper that has jammed in the paper path.
Purge relay sensor [A] detects the leading and trailing edge of each sheet that enters the purge unit. Purged paper sensor [B] detects when there is paper in the purge unit.
