(adjustment pattern).

7)

Press [EXECUTE] key.

When the gray balance is customized with the manual gray
balance adjustment (SIM 67-25) according to the user's
request and the gray balance is registered as the service tar-
get with SIM 67-27, if the gray balance is adjusted to that gray
balance, select the [SERVICE] target.

The printer gray balance adjustment (step 1) is automatically
performed and the gray balance check patch image is printed
out.

If there is any streak or unclear print on the printed check pat-
tern, check the print engine for any problems.

The initial setting menu of the halftone image correction is dis-
played. Press [OK] key.

The initial setting of the halftone image correction is per-
formed.

9)

Wait until [EXECUTE] key is displayed. When it is displayed,
press it.

The halftone image correction is performed.

10) When "COMPLETED THIS PROCEDURE" is displayed, the

adjustment operation is completed.

Cancel SIM46-74.

NOTE: The adjustment result becomes valid only when the both

adjustments in the copy mode and in the printer mode are
completed.

For example, if the copy gray balance adjustment (auto-
matic adjustment) is performed and the simulation is can-
celed, the adjustment result is invalid.

11) Check the copy gray balance and density.

(Refer to the item of the copy gray balance and density check.)

When the gray balance and the density are unsatisfactory after
the automatic adjustment by selecting the factory target in pro-
cedure 4), execute the manual gray balance adjustment
(ADJ11C (2)).

Also when the service target is selected in procedure 4) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual gray balance adjustment (ADJ
11C (2)).

12) Check the printer gray balance and density.

(Refer to the item of the printer gray balance and density
check.)

If a satisfactory result on the gray balance and the density is
not obtained with the automatic adjustment, execute the man-
ual adjustment (SIM 67-25) (ADJ 11E (2)).

Also when the service target is selected in procedure 7) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual gray balance adjustment (ADJ
11E (2)).

If the gray balance or density is not in the satisfactory level even
after execution of the automatic and manual adjustments, there
may be another cause.

Troubleshoot the cause, repair or perform necessary works, and
repeat the adjustment from the beginning.
