4-5-3 Signs and Measures at Poor toner cartridge
Fault
Signs
Cause & Check
Solution
Light image and
partially blank
image
(The life is ended.)
Toner
Contamination
• The printed image
is light or unclean
and untidy.
• Some part of the
image is not print-
ed.
• Periodically a noise
as "tick tick" occurs.
• Toner is fallen on
the papers periodi-
cally.
• Contaminated with
toner on prints part-
ly or over the whole
surface.
1. If the image is light or unclean
and untidy printed image -
Shake the developer and
then recheck.
(1)NG: Check the weight of the
developer
(2)OK: Lack of toner, so the life
is nearly closed.
2. Some part of image is not
printed - Shake the develop-
er and then recheck.
(1)NG: Check the weight of the
developer and clean
the LSU window with a
cotton swab, then
recheck.
(2)OK: Lack of toner, so the life
is nearly closed.
3. Periodically a noise as "tick
tick" occurs - Measure the
cycle and the weight of the
developer.
4. White vertical stripes on the
whole screen or partly :
Check the weight of the
developer.
1. Toner is fallen on the paper
periodically.
(1)Check the cycle of the
falling of the toner.
(2)Check the appearance of
both ends of the developer
OPC drum.
2.The center of the printed mat-
ter is contaminated with toner.
(1)Check whether foreign sub-
stances or toner are stuck
to the terminal (contact
point) of the developer.
(2)Check whether the state of
the terminal assembly is
normal.
1. All of 1, 2, 3 above-
(1)The weight of the developer
ended: 800g ± 20g
(2)If it become better by shaking,
replace with a new developer
after 50-100 sheets in the clos-
ing state of the life span.
2. In case of 2-
If it becomes better after clean-
ing the LSU window, then the
developer is normal.
(Because of foreign substance
on the LSU window, the image
has not been printed partly.)
3. In case of 3-
If the cycle of noise is about 2
seconds, the toner inside the
developer has been nearly
exhausted.( Purchase and
replace with a new developer
after using about 200 sheets at
the point of occurrence)
4. In case of 3-
This is a phenomenon caused
by lack of toner, so replace with
a new developer.
1. If both ends of the OPC drum
are contaminated with toner:
Check the life of the developer.
(In case of less than 820g, the
life may be expired.)
2. Check whether it could be recy-
cled.
3. If it cannot be recycled:
Replace the developer.
