1.5 To Correct Out-of-Registration Colors

Before adjustment
Paper feeding direction
The text and background are misaligned or out
of registration.
 Explanation
Colors of text or a thin line are sometimes printed out of alignment. Perform color registration control, in order
to print or copy without out-of-registration colors.
 Procedures
* The service technician must perform the adjustment in accordance with the procedure below.
* This adjustment is intended to correct misaligned colors due to differences between the paper feeding speed and
rotating speed of the transfer belt. Therefore, it will be effective, only if colors are misaligned in the paper
feeding direction (or the secondary scanning direction). This adjustment cannot improve misaligned colors in
the direction perpendicular to paper feeding (or primary scanning) or in the secondary scanning direction
periodically (partially at regular intervals). Refer to "Troubleshooting for the Image 1) Color deviation" in the
Service Manual.
