5-28 Phaser 7400 Color Printer Service Manual
Mis-Registration, Color Layers Not Correctly Registered
The image appears blurred and the primary colors are not aligning correctly into one
image. For a page oriented Long-Edge Feed, as the one shown here, the following
applies:
■ If the colors are shifted from left to right, this is mis-registration in the
process direction.
■ If the colors are shifted from top to bottom, this is mis-registration in the
scan direction.
Initial Actions:
■ If the mis-registration is in the horizontal direction, perform the color
registration adjustment, see (page 6-5).
■ If the mis-registration is in the vertical direction, clean the ADC Sensor, and
then print the Color Registration page.
