Printing and paper feeding
Names Functions
T1 paper pull-in roller This feeds recording paper from the paper tray 1.
T2 paper pull-in roller This feeds recording paper from the lower tray.
Registration actuator This detect the leading edge of recording paper, controlling
the printing start position.
This detect the leading edge/ending edge of recording paper,
identifying the recording paper size.
This detects paper jamming in the rear.
Paper feed roller The leading edge of recording page hits the reversed paper
feed roller, correcting inclination of the paper. After the
correction, the paper feed roller rotates, feeding the paper to
printing start position.
Paper ejection roller This feeds printed recording paper to the switchback roller.
Switchback actuator This detects whether the printed recording papers are ejected.
This detects the ending edge of recording paper after printing
the first side when duplex-printing, adjusting timing to reverse
the switchback roller rotation.
This detect the leading edge/ending edge of recording paper
when duplex-printing, identifying the recording paper size.
This detects whether the recording papers are fed from the
switchback roller to the duplex-printing path.
This detects paper jamming in the ejector.
Detect if paper tray 1 is set.
Switchback roller This ejects the recording paper to the output paper tray.
During duplex-printing, after feeding some of the recording
papers printed in the first side to the switchback roller, its
rotation is reversed to feed the recording paper to the
duplex-printing path.
Duplex paper feed roller During duplex-printing, this feeds the recording paper that are
fed in the duplex paper path to the paper feed roller.
