2.3 Operation of Each Part
Part name Operation
Pick-up roller Feed the paper from the paper tray.
Separation roller/Separation pad Separate into single sheet from the paper tray.
Paper feed actuator
(Paper feed sensor)
Detect whether or not the paper tray is installed.
Detect the paper jam of front part.
Detect the rear edge of paper to adjust the timing of
feeding the next paper.
Registration front actuator
(Registration front sensor)
Detect the front edge of paper and control the drive of the
registration roller. Detect the paper jam of front part.
Registration roller When the front edge of the paper hit the stopped
registration roller and the inclination of the paper is
corrected. After correction, the paper is fed.
Registration rear actuator
(Registration rear sensor)
Detect the front edge of paper to adjust the writing start
position. Detect the paper jam of center part.
Detect the front and rear edges of paper to detect the
paper size.
Belt unit Feed the paper to the drum unit for each color and transfer
toner on the paper.
Heat roller
Pressure roller
Fuse and fix the toner transferred on paper by heat and
pressure, and feed the paper to the eject roller.
Eject actuator (Eject sensor) Detect whether or not paper is ejected from the fuser unit.
Detect the rear edge of paper in 2-sided printing to adjust
the timing of switching the rotation of the eject roller. Detect
paper jam at the rear of the machine.
Eject roller 1 Feed the paper ejected from the fuser unit to the eject
roller 2.
Eject roller 2 Feed the paper ejected from the eject roller1 to the
output tray. In 2-sided printing, after some sheets of paper
are fed through the paper eject roller, its rotation is
reversed to feed the papers to the duplex tray.
(2-sided printing model only)
Duplex paper feed roller Feed the paper passed in the duplex tray to the
registration roller.
Manual feed paper empty
actuator
Detect whether paper is set in the manual feed slot.
Back cover sensor Detect whether the back cover is open.
Top cover sensor Detect whether the joint cover ASSY is open.
Document pick-up roller Feed the documents from the ADF document support.
Document separate roller/
ADF separation pad
Separate the documents fed from the ADF document
support into a single sheet of paper each.
Document detection sensor Detect whether documents are set in the ADF.
Document scanning position
sensor
Detect the scanning start position of the first and second
sides. Detect paper jam in the ADF.
Document ejection roller Feed the documents to the output tray.
ADF cover sensor Detect whether the ADF cover is opened or closed.
Internal temperature thermistor Detect the internal temperature of the machine.
