AR-BC260 SETTING AND ADJUSTMENTS 8 - 22
The following functions (HV/HT/TC/RRM/MD) of SIM 44-1 must be set to Enable.
(Adjustment items which affect the copy color balance/density but need not to be adjusted frequently. When,
however, a trouble occurs, check and adjustment must be made.)
1) Adjustment item: ADJ 1, ADJ 7, ADJ 12, ADJ 13
(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 contents.
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
