Fusing Pressure Adjustment - Gestetner B070 Service Manual

3.11.11 FUSING PRESSURE ADJUSTMENT

NOTE: The nip width 11.5 ± 0.5 mm (the difference between front and rear
measurements should be less than 0.5 mm).
1. Execute SP1109 (Fusing Nip Band Check) to enter the fusing nip band check
mode.
2. Make a copy using an A4/LT OHP sheet. Copying will start. It will stop in the
fusing unit for 30 seconds and then will exit.
NOTE: If an OHP sheet is not available, use a solid black copy on plain paper
(make the copy with the ADF open – the copy will be all black).
3. Measure the nip band width (the shiny band) at both ends.
4. It the nip band width is not within specifications at both ends, release the fusing
pressure and adjust it using the adjustment screw [A] (clockwise increases the
pressure, counterclockwise decreases the pressure).
NOTE: Loosen the lock nuts [B] before turning the pressure adjustment screw.
Re-tighten the nuts after adjusting.
5. Repeat steps 1 to 4 to check the nip band width.
