The purpose of this Service Calibration is to calibrate the nominal advance of the media. This calibration is necessary to control the exact movement of the media in order to avoid print quality problems like banding. The values from the Calibration will then be stored in the EEROM and the user can restore the Printer to these values by selecting "Restore factory" in the Advance Calibration menu.

Perform the Factory Advance Calibration whenever:

Banding is detected in prints for all HP Media standard paper types and Printheads Diagnostic is OK.
Drive Roller is disassembled or replaced.
Paper-Axis Motor Assembly is disassembled or replaced.
Electronics Module AND the Ink Supply Station are replaced.

Perform the Factory Advance Calibration as follows:

NOTE: Make sure you load HP High Gloss Photo Paper or HP Bright White Inkjet Paper in to the Printer before performing this calibration. Do NOT use any other type of media apart from HP High Gloss Photo Paper or HP Bright White Inkjet Paper otherwise the Printer will display "Calibration Error" on the Front Panel and the calibration will be cancelled.

1. In the Service Calibrations submenu, scroll to "Factory advance cal." and press Enter.

3. If media is not loaded, the following message appears on the front panel and you must load media into the Printer.

NOTE: Do NOT use any other type of media apart from HP High Gloss Photo Paper or HP Bright White Inkjet Paper.

4. The Printer will start to print the Accuracy Calibration Pattern and the following message will be displayed on the front panel:

5. The following drawing shows you the pattern that will be printed:

6. In order to measure the pattern that has been printed, load the pattern into the Printer with the printed side up and with the dotted line at the top (that is, rotated 90º).

7. Re-enter the Advance Calibration and select "Measure pattern" and press Enter.

8. The Printer will measure the alignment marks using the line sensor on the Carriage Assembly. The following message will be displayed while the Printer measures the pattern:

9. Once the calibration is completed, the following message will be displayed:
