Colours are off. Did you perform "Registration

Ask your administrator to perform "Registration
Adjustment".
If the colours are out of position in the printed output of a
colour copy job, "Registration Adjustment" can be used
to adjust the print position of each colour.

repeating calibration may improve the results.)
