In addition, when installing the new Pressure Roller Case (P/N A2504106) in machines that contain the old
case (P/N G0294106), it is necessary to replace other components at the same time. Please see TSB - 018
for a description of these parts and the cut-in serial numbers.
When replacing the Pressure Roller Case, it is necessary to remove the mounting screws of this case and
the Fusing Frame. When reattaching these screws, tighten them carefully so as not to strip the screw hole
threading. If the threading is stripped and the screw becomes loose, be sure to use only screw (P/N
04503014B) (see TSB - 014 and TSB - 023).
NOTE: We recommend replacing the Pressure Roller Case mounting screws with part number 04503014B
at the next service call.
* Please note that although the following cases can produce an Exit Area accordion jam, each has a
distinctly separate cause. Please keep these examples in mind:
•
The customer tries to forcefully pull out the jammed paper without using the Pressure Release Lever,
and the Spring Plates become damaged. Please confirm if the Spring Plates have been deformed.
•
A) The threading is stripped in the Fusing Frame/Pressure Roller Case screw holes, causing the screws
to rattle loose in their holes.
B) The Fusing Frame or Pressure Roller Case has not been set properly.
Please check to see if the screws are loose or the frames are not locked in place (push down and check
for locking snap).
•
The Junction Gate catches on the Exit Cover (1-bin Sorter installed). Confirm that the Junction Gate can
move freely back and forth without catching on the Exit Cover. See TSB - 033 for details.
•
When the Paper Exit Cover is removed and reinstalled, the Mylar (P/N A2501353) on the Fusing Upper
Cover (P/N A2501278) becomes deformed and/or pinched between the Exit Cover and mainframe (no 1-
bin Sorter installed). If the Mylar is pinched, an accordion jam will occur 100% of the time. Please
confirm whether or not the Mylar has actually been deformed and/or caught between the Exit Cover and
mainframe. See TSB - 002 for details.
