The width of paper is detected with reference to the output of the variable resistor (SVR1), which operates in conjunction with the movement of the side guide.

The side guide in the manual feed tray is set when the user moves it to place paper in the cassette.

[1] Side guide (rear)

[2] Stop arm

[3] Center gear

[4] Side guide (front)

[5] Variable resistor (SVR1)

[6] Manual feed tray

Calculate the paper width from the A/D converted value of the manual feed volume.

Register the A/D converted values of 3 points (paper width of A4, A4R, and A6R) that are the reference values to the backup RAM beforehand. (Execute the setup

in the service mode.)

Service Modes:

- Register the reference points

COPIER > FUNCTION > CST > MF-A4R

COPIER > FUNCTION > CST > MF-A6R

COPIER > FUNCTION > CST > MF-A4

- Adjustment of the foregoing reference points

COPIER > ADJUST > CST-ADJ > MF-A4R

COPIER > ADJUST > CST-ADJ > MF-A6R

COPIER > ADJUST > CST-ADJ > MF-A4

The registration roller is driven with the registration multi motor (M6).

The registration clutch (CL6) is located between the registration roller and the registration multi motor, and it controls ON/OFF of the registration roller in order to

match a paper and an image on the drum at the predetermined registration point.
