If SC76 occurs, take the following action:

1. Install the machine on a stable and level surface.

2. Place the three wedges that have been packed together with the machine under each
of the three feet.

3. If SC76 still occurs, attach the spacer to the machine according to the following
procedure.

Procedure for attaching the spacer:

1. Remove the belt cartridge.

2. Measure the gap L between side plate and OPC belt as shown in diagram 1.

3. Do one of the following actions depending the length of gap L:

Gap L (mm) Required action

0 – 3 Attach one spacer to the bearing on side A as shown in diagrams 2

& 3.

3 – 7 No action necessary

7 - 10 Attach one spacer on the bearing on side B as shown in diagrams

2 & 3.

Note: Clean the area of the bearing where the spacer will be attached with a cloth.

4. Install the belt cartridge and the turn on the machine.

5. Measure gap L after the machine has finished warming up.
