Checks
Turn OFF/ON the power switch,
and set the copy count to ‘1’. Is
‘E064’ indicated after
copying?
Set the count to ‘1’ once again,
and make a copy. Is ‘E064’
indicated after copying?
Is the contact of the transfer
charging assembly/transfer
charging roller faulty?
Remove the drum unit, and
check the primary charging
roller. Is the primary charging
roller or the contact faulty?
Remove the developing assem-
bly, and check the developing
cylinder and the contact. Is the
developing cylinder or the con-
tact faulty?
Are there scratches or tears in
the high-voltage cable (primary
charging, transfer charging,
and developing)?
Yes/No

Action
Check the harness of the DC
controller PCB and the com-
posite power supply PCB.
Perform steps 3 through 6;
then, replace the composite
