RTB Reissue
The items in bold italics were corrected or added.
General
Conventionally, one fusing unit was assigned for one mainframe. Multiple fusing units
could not be assigned for one mainframe because the mainframe could only manage the
PM counter for one fusing unit.
The system has been modified to enable application of multiple fusing units per mainframe
and independent PM counter management accordingly.
The main purpose of this system modification is to prevent image quality problems caused
by a damaged fusing belt. Continuous feeding of a particular paper size causes the paper
edges to damage the fusing belt, which generates a line on the output image when
changing to a larger paper size.
Requirements
This modification will become available by installing the firmware versions listed below.
