RTB Reissue
Affected machine’s list is simplified
This RTB has been issued to announce the information on the modified fusing unit handle.
SYMPTOM
The pins welded to the detachable fusing unit handle for some of the units could loosen
after using the handle a few hundred times to load/unload the fusing unit.
CAUSE
The pins could become loose on the currently available 3 point-welded type and 5 point-
welded type handles due to the insufficient amount of weld.
SOLUTION
The handle was modified to apply the weld to the entire periphery of the pin to secure
higher durability.
* Areas colored in red indicate the locations of the weld.
ACTION
Replace the 3 point-welded handle and the 5 point-welded handle with the modified handle
on your next service visit.
Please note that replacements are given priority to the following:
z
Customers who frequently load/unload the fusing unit
z
Units installed with the 3 point-welded or 5 point-welded handle
See the appendix for the serial numbers of the affected units.
The modified handles will be ready by the middle of January 2012 and delivered in
separate shipments until the middle of March 2012.
