Recalibrate the paper advance
Accurate paper advance is important to image quality because it is part of controlling the proper placement of
dots on the paper. If the paper is not advanced the proper distance between printhead passes, light or dark
bands appear in the print and image grain may increase.
The printer is calibrated to advance correctly with all the papers appearing in the front panel. When you select
the type of loaded paper, the printer adjusts the rate at which to advance the paper while printing. However, if
you are not satised with the default calibration of your paper, you may need to recalibrate the rate at which the
paper advances. See Troubleshooting print-quality issues on page 132 for steps to determine if paper advance
calibration will solve your issue.
You can check the paper advance calibration status of the currently loaded paper from the front panel at any
time by pressing
, then , then Image-quality maintenance > Calibration Status. The status may be one of
the following.
●
DEFAULT: This status appears when loading any paper that has not been calibrated. HP papers in the Front
Panel have been optimized by default and unless you experience image quality problems in your printed
image such as banding or graininess it is not recommended to recalibrate the paper advance.
●
OK: This status indicates that the loaded paper has been calibrated before. However you may need to
repeat the calibration if you experience image quality problems such as banding or graininess in your
printed image.
NOTE: Whenever you update the printer’s rmware, the paper advance calibration values are reset to
factory default, see Update the rmware on page 111.
CAUTION: Transparent papers and lms must be calibrated by pressing , then , then Image-quality
maintenance > Paper advance calibration > Adjust paper advance, from step four in Recalibrating the paper
advance procedure.
Recalibrating the paper advance procedure
1.
From the front panel, press , then , then Image-quality maintenance > Paper advance calibration >
Calibrate paper advance. The printer automatically recalibrates the paper advance and prints a paper
advance calibration image.
2. Wait until the front panel displays the status screen and re-print your print.
NOTE: The recalibration procedure takes approximately three minutes. Do not worry about the paper
advance calibration image. The front-panel display shows any errors in the process.
If you are satised with your print continue using this calibration for your paper type. If you see
improvement in your print, continue with step three. If you are dissatised with the recalibration, return to
the default calibration, see Return to default calibration on page 131.
3.
If you would like to ne-tune the calibration or are using a transparent paper, press , then , then
Image-quality maintenance > Paper advance calibration > Adjust paper advance.
