Feed the paper from the paper tray 1 to T1 separation roller.
Separates the paper fed from paper tray 1 into single sheets.
Detect whether or not the paper tray 1 is installed (open or
closed). Detect the paper jam of front part.
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.
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.
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.
Feed the paper to the drum unit and transfer toner on the paper.
pressure, and feed the paper to the eject roller 1.
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.
Feed the paper ejected from the fuser unit to the 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 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.
Feed the paper passed in the duplex tray to the registration
roller.
Feed the paper from the MP tray to MP separation roller.
Separates the paper fed from the MP tray into single sheets.
Detect whether paper is loaded in the MP tray.
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 LT paper tray unit.
Feed the paper from the LT paper tray unit to LT separation roller.
Separates the paper fed from LT paper tray unit into single sheets.
Detect whether or not the LT paper tray unit is installed (open or
closed). Detect the paper jam of front part.
Detect the eject/reverse position state of the gear of the paper
eject ASSY.
