FUSING UNIT
B064/B140 Series/G126 3-80 SM
3.9.11 NIP BAND WIDTH ADJUSTMENT
1. After the machine is powered on with the main switch, make an A4/LT LEF
copy, then stop the machine while the paper is still in the fusing unit by
switching it off.
NOTE: This is easier with an OHP sheet. Use an OHP sheet if you have one
available.
2. Open the front door, then turn the fusing knob to feed out the copy.
3. Measure the width of the band on the part of the image where it is particularly
black. The band, called the nip band [A], should be 9.0±0.7 mm at the center.
NOTE: When the fusing is incorrect (wrinkles, offset, curl), measure the nip
band width. The nip band width can be adjusted by changing the
position of the springs [B] on either end of the pressure roller. The
fusing temperature can also be adjusted with SP1105 (Fusing
Temperature Adjustment) for Normal, OHP, and Thick Paper.
