(The following adjustment items affect copy quality, but there is no need to adjust them frequently. In case of a trouble,
however, they should be checked and adjusted.)
1) Adjustment item: ADJ M1, ADJ M2, ADJ M4, ADJ M6
ADJ M1 DV doctor gap adjustment
ADJ M2 DV roller main pole position adjustment
ADJ M4 High voltage adjustment
ADJ M6 Image density sensor adjustment
(The following adjustment items do not affect copy quality directly.)
1) Adjustment items: ADJ M5, ADJ M11, ADJ M12, ADJ M14, ADJ M15, ADJ M16, ADJ M18, ADJ M19, ADJ M20, ADJ M23, ADJ M24, ADJ M25
(Relationship between servicing contents and copy quality adjustment)
Note that the procedures before and after the copy quality adjustment differ depending on the conditions of the machine and the servicing contents.
Follow the copy quality adjustment procedure flow to perform procedures according to the conditions.
There are following 5 major cases.
1) When installing
2) When performing the periodic maintenance
3) When replacing consumable parts in repair work
4) When not replacing consumable parts in repair/check work
5) When perform in repair/check work
