Use this RAP for fuser module related problems.
Ensure
IQ1
Image Quality Entry RAP is performed before starting this RAP.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Perform the following:
•
Enter Diagnostics,
GP 1
. Enter
dC131
. Refer to chain 10 NVM fuser setting values; 10-
028; 10-029; 10-059. Check the NVM values. If the NVM values are increased, fusing
performance is improved, but contamination can occur. If the NVM values are decreased,
fusing performance is reduced.
•
Poor fusing can be caused by alternative quality paper and heavily embossed envelopes,
GP 20
. If the customer is using alternative quality paper, select the card stock setting on
the GUI. Adjusting 10-059 only changes the fuser temperature when card stock is
selected. Some 200 gsm papers do not fuse correctly.
–
Check that the customer is using tray 1 and tray 2 for alternative quality paper or
heavy weight paper.
–
Refer to
IQS 3
Fusing.
•
Check the following for wear and contamination:
–
Stripper fingers. If possible remove the contamination. If the stripper fingers are
damaged or worn, install a new fuser stripper fingers, (35-55 ppm)
PL 10.8 Item 4
or
(65-90 ppm)
PL 10.10 Item 4
.
–
Fuser rolls. If the fuser rolls are damaged or worn, install a new fuser module, (35-55
ppm)
PL 10.8 Item 1
or (65-90 ppm)
PL 10.10 Item 1
.
NOTE: Do not change the fuser module, because of the appearance of wrinkles on
the pressure roll. This is normal for the pressure roll, caused by the conductive
sleeve that stretches as the silicon rubber base of the roll expands. The pressure
rolls are more wrinkled due to the higher run temperatures on the 65-90 ppm
machines.
–
Fuser web. If this is heavily contaminated or shows no sign of advancement, go to
the
10A
Fuser Web Motor RAP.
