Procedures
* The service technician must perform the adjustment in accordance with the procedure below.
(1) Make sure that no out-of-registration colors are visible on an original.
(2) Check the direction in which colors are misaligned.
* 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.
(3) Enter adjustment mode [05] and print out the test print pattern to correct out-of-registration colors.
(a) Enter adjustment mode [05], select code [4719], and then press the [START] button.
• Registration control will be forcibly performed.
(b) Enter code [104] corresponding to a desired test print pattern. Press the [FAX] button.
• Paper is fed from the drawer to print out a test print pattern.

* Jot down the "paper feeding direction" on the printed test print pattern beforehand. This facilitates
identifying out-of-registration colors in the subsequent adjustment. Use only the second page of
the test print pattern.
