Cause & Check
The printed image 1. If the image is light or unclean and
untidy -
Shake the print cartridge, then
recheck.
(1) NG: Weigh the print cartridge
(2) OK: Lack of toner, near end-of-life.
Some part of the 2. Some part of image is not printed -
Shake the print cartridge, then
recheck.
(1) NG: Weigh the print cartridge, and
clean the LSU window with a cotton
swab, then recheck.
(2) OK: Lack of toner, near end-of-life.
A "tick tick" noise 3. A "tick tick" noise occurs
periodically - Measure the interval,
and weigh the print cartridge.
White vertical 4. Weigh the print cartridge.
Toner periodically 1. Toner contamination.
(1) Check the pattern of the toner
contamination.
(2) Check the appearance of both
ends of the print cartridge OPC drum.
Contaminated with 2. The center of the printed matter is
contaminated with toner.
(1) Check whether foreign substances
or toner are stuck to the terminal
(contact point) of the print cartridge.
(2) Check whether the state of the
terminal assembly is normal.
Solution
1. All of 1, 2, 3, 4:
(1) The weight of the print cartridge
at end-of-life: 800 g ± 20 g
(2) If image improved by shaking,
replace with a new print cartridge
after 50-100 sheets.
2. If it improves after cleaning the
LSU window, then the print cartridge
is normal.
(Because of foreign substance on
the LSU window, the image has not
been printed completely.)
3. If the cycle of noise is about 2
seconds, the toner inside the print
cartridge has been nearly exhausted.
(Purchase and replace with a new
print cartridge after printing about
200 sheets).
4.This is a phenomenon caused by
lack of toner; replace with a new
print cartridge.
1. If both ends of the OPC drum
are contaminated with toner:
Check the life of the print cartridge.
(In case of less than 1000 g, the life
may be expired.) or check the rate of
remain toner if remain toner is
below 10% the toner is almost
empty.
2. Check whether it could be
recycled.
3. If it cannot be recycled:
Replace the print cartridge.
