Fusing NIP Band Check By-pass (Checking the NIP band)

You can check the nip band to see if the fusing unit is in a good condition–especially, if the hot roller

and pressure roller are correctly installed.

1. Place an OHP sheet on the by-pass tray.

2. Activate the SP mode.

3. Select SP1-152-001.

4. The copier feeds the OHP sheet, and stops it between the hot roller and the pressure roller for

about 40 seconds.

5. Wait until the OHP sheet is output.

6. After output, quit the SP mode.

You see an opaque stripe on the OHP sheet. This is the trace of the nip band. The normal nip band is

symmetrical on the OHP sheet. Both ends are slightly thicker than the center.

• There are no specifications or standards for the nip band of this copier.
