5) The display below is shown. Select A4 or 8.5" x 11" size
paper, and press the EXECUTE key.
The test pattern for adjustment is printed, and the adjustment
menu is displayed.

(Note) Use paper of the same or nearest color as the background
color of the test chart (UKOG-0305FCZZ) as far as possi-
ble.
6) Collate the test chart (UKOG-0305FCZZ) and the test pattern
patch density.
Place the test chart on the printed pattern so that the printed
pattern can be seen from the cut sections. Put several sheets
of white paper beneath the printed pattern.

Find out the density point in the test pattern array 1 which lies
between the Lower Limit and the Upper Limit of the test chart
(1).
Put a check mark on the density point found in the procedure
above.
If there is no density point which satisfies the above condition
in test pattern array 1, perform the following procedures.
• When the test chart (1) density is higher than the maximum
density (+4) in the array 1:
→
Put a check mark on "+4" in the array 1.
• When the test chart (1) density is lower than the minimum
density (–4) in the array 1:
→
Put a check mark on "-4" in the array 1.
For densities of Test chart (2) to (12), perform the same proce-
dure as procedure 6).
7) Set the adjustment points (+4 to –4 on the right side) corre-
sponding to the density points (12 positions) marked with
check mark on the test pattern on the adjustment menu.
