Mis-Registration, Color Layer Not Correctly Registered In The Process Direction - Xerox Phaser 6250 Service Manual

Mis-Registration, Color Layer not Correctly Registered
in the Process Direction
The four colors of the image are not
registered correctly into one image.
Initial Actions:
If the mis-registration is in the
horizontal direction, perform the color
registration adjustment. See
"Horizontal and Vertical Color
Registration" on page 6-3.
If the mis-registration is in the vertical
direction, clean the CTD (ADC)
Sensor, then print the Color
Registration Page. This forces the
printer to perform a vertical registration
adjustment. Check to see if the problem still appears before using this procedure.
