Colour Adjustments
This is used to adjust greyscale and colour balance.
Touch [Printer Settings] key and touch the [Colour Adjustments] key and configure the settings.
Auto Colour Calibration
This is used to perform automatic colour correction when 
the colour in colour copies is off. The machine prints a 
test patch, the test patch is scanned, and the colour is 
automatically corrected.
After the [Execute] key is touched and a test patch is 
printed, a message appears prompting you to begin 
automatic calibration. Place the test patch on the 
document glass as shown below so that the narrow line 
of one-side of the paper is on the left and touch the 
[Execute] key.
Lay copy paper (about five sheets) that is the same size 
as the test patch on top of the placed test patch, and 
gently close the automatic document feeder.
The following two print ports are available on the 
machine:
• USB port
• Network port

• Before executing Auto Colour Calibration, check to 
see if the registration adjustment is correct. If the 
registration adjustment is not correct, perform 
"Registration Adjustment" (page 96).
• If the colour is still off after performing Auto Colour 
Calibration, repeating Auto Colour Calibration once 
again may improve the colour.
