1.Initializing the ROM
1) Press [MENU]; then, press [#] to start service mode.
2) Move to [#CLEAR], and press [OK].
3) Move to [ALL], and press [OK] to initialize the ROM.
2. PWM Adjustment
1) Press [MENU], an then press [#] to start service mode.
2) Go to [#TEST MODE]; then, press [OK] and [*] to start [ADJUST TEST].
3) Press [1], and see that [OK] is indicated.
At the end of PWM adjustment, the machine starts its initialization sequence.
5.1.4 Fixing System
5.1.4.1 Checking the Nip Width of the Lower Fixing Roller
0008-1739
The fixing unit is not designed to allow the adjustment of the pressure (nip width); however, incorrect nip width can cause fixing defects.
Check the nip width by following the procedures below. If the nip width does not satisfy specifications, replace the fixing unit.
1) Make an all-black print of A4 size using the cartridge of this printer by operating external devices, and take the print to the customer's site.
2) Place the all-black print facing down on the Cassette.
3) Select face-up delivery.
4) Press the test print switch.
5) Open the delivery door immediately after the leading edge of the print has come out to the face-up tray. Take out the print from the printer after 10 seconds from
turning off the power switch.
6) Measure the width of the glossy band across the paper and check that it meets the following requirements shown in figure.
- Center (a): 6 to 7.5 mm
- Difference between right/left and center (b - a, c - a): 0.6 mm or less
- Difference between right and left (|b - a|): 0.5 mm or less
