5. MACHINE CONDITIONS

SYMPTOM:
Toner end condition appears on the LCD just after installing a new machine
with a new toner bottle.
CAUSE:
Due to the design of the toner hopper, it takes a short amount of time to
completely fill it with toner. During this time, it is possible for the toner end
condition to occur. In particular, this tends to happen when continuous
copies are made from a high image density original (example) just after
installation (developer initial setting).
SOLUTION:
Make 50 ~ 100 copies to fully supply the toner into the toner hopper. Stop
the machine every 10 copies to allow the machine to create the ID sensor
pattern to maintain precise toner density.
SYMPTOM:
The copy counter indicates "8" even if another key (for example, the Clear
Modes key) is pressed. For instance, if the Clear Modes key is touched three
times, the copy counter indicates "888".
CAUSE:
The grounding wire terminal is touching the operation panel board circuit
pattern. This may occur after the operation panel is opened to install the
guidance ROM's at installation. If the grounding wire is pulled strongly, the
terminal may be rotated and bent. If the bent terminal is pressed against the
insulating sheet and touches the legs of electrical elements behind the
insulating sheet, a short-circuit may result.
Good
No good
SOLUTION:
Correct the bent terminal and repair the insulating sheet with insulating tape
such as teflon tape.
