IMPORTANT NOTICE
With Engine f/w version 1.66:04 1.67.04 or newer, the fusing ID chip can store the PM
counter of the web cleaning unit.
How to enable the new feature:
Set SP1-998-001 to ‘1’ (enable). The PM counter stored on the fusing ID chip will
synchronize with the counter stored in the engine.
For machines that use multiple fusing units:
DO NOT swap the web cleaning unit. Always use the same web cleaning unit and fusing
unit as a set.
Web cleaning unit replacement procedure:
Do either of the following after replacing the web cleaning unit (to synchronize the PM
counter):
 Clear the web cleaning unit PM counter
 Print 50 pages
Synchronization of the web cleaning unit PM counter is performed as follows:
 Clear PM counter : Engine  Fusing ID chip
 Print 50 pages : Engine  Fusing ID chip
 Replace the fusing unit and
web cleaning unit as a set : Fusing ID chip  Engine
Note: See RTB RD074110 for procedures on how to replace PM parts of the fusing unit
for machines that use multiple fusing units.
