7.11.8.11 Removing the Black
Developing Unit
Points to Note About the Work
1 The machine's developing unit is not equipped with
a developing cylinder protection cover. Take full care,
therefore, not to damage the developing cylinder
when you have detached the developing unit.
The waste toner collecting inside the machine can
move into the fixing/feeding assembly through the
outlet; be sure to place paper under the process unit for
the work.
2. The machine's black developing unit is equipped
with a potential sensor. Do not touch the sensor
window [1] indicated in the figure. Moreover, take
care not to drop the black developing assembly or
otherwise subject it to impact so as to avoid damage to
the potential sensor.
