Nip Band Width Measurement (SP1109)
When paper wrinkling or image off-set occurs, the pressure from the pressure roller can be
adjusted by changing the position of the pressure springs. At this time, the nip band width
can also be checked with SP1109, as follows.
1. Do a free run (SP5802) for about 50
sheets.
2. Access SP1109 and press the “1” key.
3. Press Copy Window to return to the copy
window.
4. Place an OHP sheet (A4/8.5”x11”
sideways) on the by-pass tray or in the
2nd paper tray.
5. Press the “Start” key.
6. The OHP sheet is stopped in the fusing unit for about 20 seconds, then it will be fed
automatically.
7. Check the width of the nip band [A] around the center of the OHP. The relationship
between the position of the pressure spring and the width is as follows.
1. Pressure spring position Nip band width
Upper (default position) 5.2 ±0.5 mm
Lower 5.3 ±0.5 mm
2. Envelope feed mode (green lever down) at the default
pressure spring position
4.7 ±0.5 mm
If the width is out of the above specification, the pressure spring should be replaced.
