The paper feeder uses the Tray 3 feed (SR4) to detect the presence of paper and to check whether

paper has jammed.

The paper-feeder driver identifies a jam if the sensor detects paper at a specified timing stored in the

paper-feeder driver. The paper-feeder driver stops printing and notifies the formatter through the DC

controller of the jam. The paper feeder detects the following jams:

●

Pickup delay jam: The paper-feeder media-feed sensor does not detect the leading edge of media

within a specified period from when the paper-feeder pickup solenoid is turned on.

●

Pickup stationary jam: The paper-feeder media-feed sensor does not detect the trailing edge of

media within a specified time period from when the sensor detects the leading edge.
