Operation of the Second paper feed unit

When the paper cassette (tray 1) is placed in the printer, a flag molded to the right side of the tray, contacts the release lever which rotates the paper transfer roll allowing it to contact the paper in the tray.

When the command is given to start printing, the optional paper tray stepper motor rotates, rotating the respective reduction gears. The rotating reduction gears cause the gears attached to the paper feed roller and paper transfer roller to start rotating. The paper feed roller contacts the paper causing the paper to feed to the idler roller. The one way clutch causes the idler roller to rotate feeding the paper past the paper pass sensors located prior to the idler roller and the timing roller. After a predetermined period of time, the paper feed clutch is turns off and the paper feed roller and paper transfer roller stop rotating. At this point, the paper stops at the timing roller and pauses. If the pass thru sensors do not detect paper from the cassette, a paper jam displays.
