Detect whether or not paper is loaded.

Detect the paper jam of front part.

Registration front actuator

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 is made, the registration roller rotates to feed

the paper to the belt unit.

Registration rear actuator

Detect the passage of paper and adjust the starting

position for writing on a sheet of paper.

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 paper eject roller 1.

Paper eject actuator

Detect whether or not paper is ejected from the fuser unit.

In the case of the duplex printing, detect the rear edge of

paper and adjust the timing of the paper eject roller 2 and 3

switching.

Paper eject roller 1

Feed the paper ejected from the fuser unit to the paper eject

roller 2.

Paper eject roller 2

Feed the paper to the paper eject roller 3.

In the case of the duplex printing, after the paper is fed from

the eject roller 3 up to a certain point with the front of the sheet

printed, the eject roller 3 rotates conversely and feeds the

paper to the duplex tray.

Paper eject roller 3

Eject the paper to the face-down output tray.

In the case of the duplex printing, after the paper is fed from

the eject roller 3 up to a certain point with the front of the sheet

printed, the eject roller 3 rotates conversely and feeds the

paper to the duplex tray.

DX 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.

MP separation roller,

MP separation pad

Separate into single sheet from the MP tray.

MP paper empty actuator

Detect whether paper is loaded in the MP tray.

MP registration front

actuator
