Notes:
1. When the web pushing roller has been replaced, reel the web for 3 to 5 turns by hand.
2. Check if the cleaning web is tightly reeled after it has been installed in the fuser unit.
3. Turn the jam access knob of the fuser unit for 10 to 15 times to fit the web and the fuser roller.
At this time, check if there is no installation defect in the unit.
4. Check the secure installation of the cleaning web as follows:
- Be sure that the cleaning web does not hang out of the space between the upper entrance
guide and the fuser roller when it is seen from the fuser unit entrance side.
- Open the fuser unit cover and make sure that there are no slacks or creases on the clean-
ing web.
5. Start the PM Support mode (6S) to reset the counter of the cleaning web when the web has
been replaced, otherwise the cleaning ability of the web may be narrowed.
At the first power-ON after this counter reset, the web motor rotates for 65 seconds.
6. Turn the power of the equipment ON. Then confirm that the message "READY" has appeared
on the touch panel.
7. Perform the final check of the cleaning web (same as Step 4 above).
8. When the web motor is rotated at the output check in the Test mode (03-124), the cleaning
web may be slackened. Do not rotate the motor for more than 10 seconds to prevent the web
from being slacked.
9. It is recommended to replace all the supplies for the fuser unit at the same time. If it is neces-
sary to replace the cleaning web before it is finished for any reason, set the counters manu-
ally for the newly replaced web according to its previous usage.
Counter related to the life span control of total feeding amount of the cleaning web
Present output pages for control: 08-1252-6
Total feeding amount for control: 08-1252-7
PM support screen related counter
Cleaning web counter: 08-1252-3
Also, when replacing the web pushing roller or one-way clutch which is half-way used, set the
following counters manually.
Web pushing roller: 08-1254-0, 08-1254-3
One-way clutch: 08-1338-0, 08-1338-3
Additionally, when the present output pages for control (08-1252-6) has reached the setting
value to display that the cleaning web is consumed (08-405), the time to replace the cleaning
web appears on the screen and the feeding amount becomes small.
If the cleaning web which has exceeded its life span is used continuously, this could damage
the fuser roller. Replace the cleaning web as soon as possible when it is finished.
