MX-M565N  ADJUSTMENTS AND SETTINGS  4 – 54

 

Before execution of the printer gray balance/density adjustment,
the copy gray balance/density adjustment must have been com-
pleted properly.

* Basically same as when the copy gray balance/density adjust-

ment is required.

* After the copy gray balance/density adjustment.

 

The gray balance adjustment (auto adjustment) is used to adjust
the print density of automatically with SIM 67-24 or the user pro-
gram.

When this adjustment is executed, the gray balance adjustments of
all the print modes are revised.

There are following two modes in the auto gray balance adjust-
ment.

1)

Auto gray balance adjustment by the serviceman (SIM 67-24 is
used.)

2)

Auto gray balance adjustment by the user (The user program
mode is used.) (The gray balance target is the service target.)

The auto gray balance adjustment by the user is provided to
reduce the number of service calls.

If the print gray balance is lost for some reasons, the user can
use this gray balance adjustment to recover the balance.

When, however, the machine has a fatal problem or when the
machine condition is greatly changed, this function does not
work effectively.

On the other hand, the auto gray balance adjustment by the
serviceman functions to recover the normal gray balance
though the machine condition is greatly changed. If the
machine has a fatal problem, repair and adjust it for obtaining
the normal gray balance.

To perform the adjustment, the above difference must be fully
understood.
