U need to see it happen on which process unit, then check the main charger unit and developer material is enough...
SOURCE: can you please giv a
CE40: Image quality control test pattern abnormality: The test pattern
is not formed normally. If you switch off at the right hand side of the machine, wait
10 secs then back on again, It should clear. I think it is caused by condensation.
It can also be transfer belt failure, or paper rubbing against the transfer belt.
It could be
because the Developer Unit failed to Pass the Close Looping Check by
the machine
every time it boots.... check for fault from 08-824 if the
value of any color is " 1 "
means abnormal occur.... check for foreign
matters on the dev tank...the
simplest way is clean all 3 tanks...then
reset it back to "0" then do a 05-200 and
05-396-4-Fax-1624-Set
95% solved the case
