ColorCalibration
This machine contains a calibration function that automatically makes adjustments to compensate for changes that
occur over time due to variations in the ambient temperature and humidity. So that the highest quality color printing can
be maintained, this color calibration operation is carried out automatically each time the power to the machine is turned
on. If color tone does not improve or color drift does not improve after executing this color adjustment, perform color print
position correction on the following:
Color Registration Procedure (page 10-29)
1
Display the screen.
[System Menu/Counter] key > [ā²] [ā¼] key > [Adjust/Maint.] > [OK] key > [ā²] [ā¼] key >
[ColorCalibration] > [OK] key
2
Perform the Color Calibration.
Select [Yes] to execute Color Calibration.
"Completed." is displayed and the screen returns to the Adjust/Maint. menu.
Color Registration Procedure
This function is available to resolve color drift. If it is not resolved by normal registration or to perform more detailed
settings, use the detailed settings.
Normal Registration
1
Display the screen.
[System Menu/Counter] key > [ā²] [ā¼] key > [Adjust/Maint.] > [OK] key > [ā²] [ā¼] key >
[Color Regist.] > [OK] key > [ā²] [ā¼] key > [Normal] > [OK] key
2
Print the chart.
[ā²] [ā¼] key > [Print Chart] > [OK] key > [Yes]
A chart is printed. On the chart, for each of M (magenta), C (cyan) and Y (yellow), 3 chart
types are printed on one sheet: H-L (left), V (vertical), H-R (right).
After printing, you will return to the advanced menu for color printing position correction.
Before performing color registration, be sure to perform ColorCalibration on page 10-29. If color drift remains,
perform color registration. By performing color registration without performing Color Calibration, the color
drift will be resolved once, however, it may cause the serious color drift later.
