2 Press the right side of the [VALUE] key to increase the value, or press the left side to decrease it,
until the number corresponding to the oval that most closely matches the background pattern
appears.
3 Press
[SELECT] to save the value. An asterisk (*) appears next to the selected setting.
Step 5: Adjust the black (K) density setting.
Examine the black density bar (K). If the center oval matches the background pattern more than the
other ovals, the black density does not need to be adjusted and you should continue with the next
step. If not, use the following steps to adjust the density:
1 Press
[ITEM] until BLACK DENSITY appears.
2 Press the right side of the
[VALUE] key to increase the value, or press the left side to decrease it,
until the number corresponding to the oval that most closely matches the background pattern
appears.
3 Press
[SELECT] to save the value. An asterisk (*) appears next to the selected setting.
Step 6: Reprint the color balance calibration page. (See step 1.)
Step 7: Adjust the gray balance.
Note Adjusting densities using the gray balance pattern allows you to fine-tune color balance. This process
affects all four color bars.
Examine the gray balance circles in the box at the bottom of the color balance calibration page. If
the circle in the center most closely matches the background pattern, then the gray balance does
not need to be adjusted. If the circle does not match, use the following steps to adjust gray balance.
1 Locate the gray circle that most closely matches the background. The magenta (M) and yellow
(Y) numbers associated with this circle indicate the optimum gray balance settings for these
colors.
2 Adjust the magenta and yellow settings (yellow is horizontal and magenta is vertical) until the
gray circle is in the middle. Use the values from the bars above to select the value to be
entered.
3 After making adjustments to the magenta and yellow settings, press
[GO] to return the printer to
the
READY state.
