MX3500N ADJUSTMENTS 6 – 32
(The following items affect the copy color balance/density
adjustment, and must be checked and adjusted before execu-
tion of the image quality adjustments.)
1) The following adjustment items must be adjusted properly.
2) The set values of the following simulations must be set to the
default values.
3) The following items (correction functions) of SIM 44-1 must be
set to ENABLE (default).
(The following items affect the copy color balance/density
adjustment, but it is not required to adjust them frequently.
When, however, a trouble occurs, check and adjust them.)
1) The following items must be adjusted properly.
(Relationship between the servicing job contents and the copy
color balance/density adjustment)
Note that the preliminary jobs before execution of the copy color
balance/density adjustment depend on the machine status and the
servicing conditions.
Follow the flowchart of the copy color balance/density adjustment
procedures depending on the actual conditions.
There are following four, major cases.
1) When installing the machine.
2) When the periodic maintenance is performed.
3) When a repair, an inspection, or a maintenance is performed.
(When a consumable part is replaced.)
4) When a repair, an inspection, or a maintenance is performed.
(Without replacement of a consumable part)
