Note
Symptom occurs only
immediately after
machine power-on.
Loose seal causes
higher friction.
Insufficient lubricant
causes higher friction.
Jam037 (fusing unit) is
a system forced
termination status;
highly likely to cause
compressed developer
between the
components.
No front door open
while machine is
working.
・ Incomplete
developer
replacement causes
the developer to
increase in the unit.
・ See RM077072 for
details on how to
completely clear out
the developer from
the unit.
See RTB
RM077102.
