Adjustment/Maintenance
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:

[ ▲ ] [ ▼ ] key > [ Print Registration Chart ] > [ OK ] key > [ OK ] key
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).
NOTE
To perform Registration, verify that either Letter or A4 paper is loaded into a cassette.
IMPORTANT
Before performing Registration, be sure to perform ColorCalibration on page 9-21 . If color drift remains,
perform registration. By performing Registration without performing Color Calibration, the color drift will be
resolved once, however, it may cause the serious color drift later.
