4.5.7 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. Activate the SP mode.
2. Select SP1-109-001.
3. Specify "1."
4. Press the OK key.
5. Press the
key. The copy mode is activated.
6. Place an OHP sheet on the by-pass tray.
7. Press the
key. The copier feeds the OHP sheet, and stops it between the hot roller and
the pressure roller for about 20 seconds.
8. Wait until the OHP sheet is output.
9. Press the
key.
10. Make sure SP1-109-001 is selected.
11. Specify "0".
12. Press the OK key.
13. 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.
