RTB Reissue
The items in bold italics were added.
General
The Hot Roller installed in the fusing unit of the Aries was found with a defect in which the rubber
covering the hot roller was shifted. (See the photo below)
Cause
The defect was caused by a fault in the manufacturing process where the rubber was not heated to
the prescribed time and was not hardened enough.
Solution
Manufacturing and check processes have been revised to prevent the fault.
A New part number has been registered for the Hot Rollers manufactured under the revised
processes.
NOTE
The defective Hot Rollers were installed ONLY in the fusing units stocked as spare service
parts, which have all been replaced with the proper hot roller.
Aries machines in stock are all installed with the proper hot roller regardless of the hot roller p/n.
(The hot roller p/n could be the former M0774105 but is not defective.)
Please DO NOT USE the hot roller registered with the p/n M0774105 if procured separately as
a service part.
