CHAPTER 5 TROUBLESHOOTING

Cleaning the Registration Roller

If the dirt is limited,

1) Remove the screw, and detach the ADF

controller cover.

2) Set the DIP switch (SW1) on the ADF con-

troller PCB as shown in Figure 5-193.

3) Place about ten sheets of copy paper on the

tray.

4) Press the push switch (SW2) on the ADF

controller PCB to end the operation.

If the dirt is excessive,

1) Open the upper cover, and open the feeding

guide.

2) Remove the two screws, and detach the re-

versing guide.
