Colour misregistration
Recommendation

To improve the colour density, calibrate the colours using
first the Touchscreen and then the printer driver (see
Calibration on page 83).

To adjust the print position of colours for sharper edges,
perform an automatic colour registration using the
Touchscreen (see Auto Registration on page 84).

Adjust the copy density and contrast if you are copying (see
Advanced User's Guide: Adjusting Density and Contrast).

Make sure Toner Save mode is off in the Touchscreen or the
printer driver (see Software User's Guide).

If the print quality of the black portion is not what you
expected, select the Print Text in Black check box in the
printer driver (see Software User's Guide).
If the print quality is poor, clear the Improve Grey Colour
check box in the printer driver (see Software User's Guide).

Identify the colour causing the problem and put in a new
toner cartridge (see Replacing the toner cartridges
