(Relationship between the service contents and the copy color balance/density adjustment)
Note that procedures before and after the copy color balance/density adjustment differ depending on the machine status and the servicing job con-
tents.
Perform proper procedures according to the flow of the copy color balance/density adjustment.
There are following five major cases:
1) When installing
2) When periodic maintenance
3) When consumable part is replaced in repair work
4) When consumable part is not replaced in repair/checking work
5) Other repair/check
