Troubleshooting paper issues 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 using custom paper or not satisfied 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 125 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 at any time by pressing the View loaded paper key on the front panel. The status may be one of the following. ● DEFAULT: This status appears when loading an HP paper. 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. ● RECOMMENDED: This status appears when a new paper is created. The paper advance values for this paper are inherited from the family type. In these cases it is recommended you perform a paper advance calibration to optimize the values. ● 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 firmware, the paper advance calibration values will be reset to factory default, see Update the firmware on page 102. CAUTION Transparent papers and films must be calibrated using the Image Quality Maintenance menu, Advance > Adjust paper advance, from step four in the Recalibrating the paper advance procedure. Recalibrating the paper advance procedure 1. Press the Menu key to return to the main menu and select the Image Quality Maintenance menu icon , then 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 satisfied 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 dissatisfied with the recalibration, return to the default calibration, see Return to default calibration on page 123. 3. If you would like to fine-tune the calibration or are using a transparent paper, press the Menu key to return to the main menu and select the Image Quality Maintenance menu icon Advance > Adjust paper advance. , then 4. Select the percentage of change from -100% to 100%. To correct light banding, decrease the percentage. To correct dark banding, increase the percentage. 122 Chapter 11 Troubleshooting paper issues ENWW

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 using custom paper or not satisfied with the default calibration of your paper, you

may need to recalibrate the rate at which the paper advances. See

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 at any time by pressing

the

View loaded paper

key on the front panel. The status may be one of the following.

●

DEFAULT: This status appears when loading an HP paper. 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.

●

RECOMMENDED: This status appears when a new paper is created. The paper advance values

for this paper are inherited from the family type. In these cases it is recommended you perform a

paper advance calibration to optimize the values.

●

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 firmware, the paper advance calibration values

will be reset to factory default, see

the paper advance calibration image. The front-panel display shows any errors in the

process.
