Factory Advance Calibration
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.
