Operation
T1 paper pick-up roller
Feed the paper from the paper tray 1 to T1 separation roller.
T1 separation roller,
T1 separation pad
Separates the paper fed from paper tray 1 into single sheets.
T1 paper feed actuator
(T1 paper feed sensor)
Detect whether or not the paper tray 1 is installed (open or
closed). Detect the paper jam of front part.
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.
Detect whether or not the paper is fed from the paper tray 1.
Registration roller
Hit the front edge of the paper to the stopped registration roller
and the inclination of the paper is corrected. After correction is
made, the registration roller rotates to feed the paper to the belt
unit.
Registration rear actuator
(Registration rear sensor)
Detect the passage of paper and adjust the starting position for
writing on a sheet of paper.
Detect the paper jam of the front part and center part.
Detect the rear edge of paper and identify the paper size.
Belt unit
Feed the paper to the drum unit 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 1.
Eject actuator
(Eject sensor)
Detect whether or not paper is ejected from the fuser unit.
In the case of the 2-sided printing, detect the rear edge of paper
and adjust the timing of the eject roller 2 and 3 switching.
Eject roller 1
Feed the paper ejected from the fuser unit to the eject roller 2.
Eject roller 2
Feed the paper to the eject roller 3. In the case of the 2-sided
printing, after the front of the sheet is printed and the paper is
fed to the eject roller 3 up to a certain point, the eject roller 2
rotates conversely and feeds the paper fed from the eject roller 3
to the duplex tray.
Eject roller 3
Eject the paper to the face-down output tray. In the case of the
2-sided printing, after the front of the sheet is printed and the
paper is fed up to a certain point, eject roller 3 rotates
conversely, and the paper is fed to the eject roller 2.
Duplex paper feed roller
Feed the paper passed in the duplex tray to the registration
roller.
MP paper pick-up roller
Feed the paper from the MP tray to MP separation roller.
MP separation roller,
MP separation pad
Separates the paper fed from the MP tray into single sheets.
MP paper empty actuator
(MP paper empty sensor)
Detect whether paper is loaded in the MP tray.
MP registration front
actuator (MP registration
front sensor)
Detect the front edge of paper from MP tray and control the drive
of the registration roller. Detect the paper jam of MP part. Detect
whether or not the paper is fed from the T2 paper tray unit.
T2 paper pick-up roller
Feed the paper from the T2 paper tray unit to T2 separation roller.
T2 separation roller,
T2 separation pad
Separates the paper fed from T2 paper tray unit into single sheets.
T2 paper feed actuator
(T2 paper feed sensor)
Detect whether or not the T2 paper tray unit is installed (open or
closed). Detect the paper jam of front part.
Paper eject origin sensor
Detect the eject/reverse position state of the gear of the paper
eject ASSY.
