Functions
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 detects paper jamming in the ejector.
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.
During duplex-printing, this feeds the recording
paper that are fed in the duplex paper path to the
paper feed roller.
After the registration actuator detects the leading
edge of the paper, it pushes the recording paper
against the stopping paper feed roller, and corrects
inclination of the paper.
This feeds the recording paper from the MP tray to
the paper feed roller.
After the registration actuator detects the leading
edge of the paper, it pushes the recording paper
against the stopping or reverse-rotating paper feed
roller, and corrects inclination of the paper.
This detects whether the recording paper are set
on the MP tray.
This feeds the recording paper from the paper tray
#3 to the Intermediate roller.
After the 3rd tray paper pull-in actuator detects the
leading edge of the paper, it pushes the recording
paper against the reverse-rotating or stopped
intermediate roller, and corrects inclination of the
paper.
This feeds the recording paper from the T3 paper
pull-in roller to the paper feed roller.
After the registration actuator detects the leading
edge of the paper, it pushes the recording paper
against the reverse-rotating or stopped paper feed
roller, and corrects inclination of the paper.
This detects the leading edge of recording paper
and switches drive from the T3 paper pull-in roller
to intermediate roller.
