Hints and tips
Fuser hints and tips
Extending fuser life
To extend the life of your fuser, Xerox recommends the usage of multiple fusers. Multiple
fusers provide maximum copy/print output for longer periods of time and ensure image
defects on output are avoided. Depending on the types of jobs run and their frequency,
you may want more than one fuser available:
one fuser for larger paper
• one fuser roll for smaller paper
Preventing Fuser Jams
1. Many of the special media types (i.e. all Coated papers, Labels and Heavyweight 2
papers) should be fed face-up (non-inverted). If they are mistakenly fed face-down,
jams are very likely to occur at the entrance to the Inverter. Many of these jams can
result in Fuser damage. Setting the media type by the GSM is important. When
selecting the media, note the GSM of the paper and select the proper paper type
(mode).
Plain Mode 64 to 105 gsm
Heavyweight 1 or Coated 1 Mode 106 to 176 gsm
Heavyweight 2 or Coated 2 Mode 177 to 220 gsm
Heavyweight 2 or Coated 2 Mode 221 to 300 gsm
Note
Setting the media type on the machine UI does not apply to printing from the
customer's desktop. If the customer attempts to send a print job and selects Use
Machine Settings in the print properties screen, then it is possible that the media
type may not be the correct weight in the paper tray, and may lead to Fuser or Inverter
jams. Therefore, it is recommended that the customer select the proper media type
from the print driver, and never select Use Machine Settings.
2. Multi-sheet Feeds from Bypass: Fan the paper stack before loading it into the Bypass
tray to prevent Multi-sheet feeds. If this problem persists, replace paper with a fresh
ream.
