3.10.8 NIP BAND WIDTH ADJUSTMENT
NOTE: 1) The fusing unit must be at operating temperature when this adjustment
is carried out.
2) Place an OHP sheet on the by-pass feed table before starting this
procedure.
3) Use only A4/LT LEF. (Other OHP sheet sizes may cause a paper jam.)
[A]: Pressure roller
[B]: Hot roller
1. Enter SP mode, and run SP1-109.
2. Press ". The machine feeds the OHP sheet into the fusing section, stops it
there for 20 seconds, then ejects it to the copy tray.
3. Check that the nip band (the opaque stripe) across the ejected OHP sheet is
symmetrical, with both ends slightly thicker than the center.
NOTE: There is no standard value for the nip band on this machine. Make the
adjustment based on the band's appearance.
4. If the band is not as described above, change the position of the spring hooks
[C] (one on each side), and then check the band again.
NOTE: The higher hook position produces greater tension.
