HP Latex 3000 Printer Series - Substrate-advance compensation

Accurate substrate advance is important to print quality because it is part of controlling the proper placement of dots on the substrate. If the substrate does not advance the proper distance between printhead passes, light or dark bands appear on the print, and there may be an increase in graininess.
The printer has a substrate-advance sensor and is calibrated to advance correctly with most of the substrates that appear in the Internal Print Server. When you select the type of loaded substrate, the printer adjusts the rate at which to advance the substrate while printing. However, if you are using a custom substrate or not satisfied with the default calibration of your substrate, you may wish to change the substrate-advance compensation. See Troubleshoot print-quality issuesTroubleshoot print-quality issues for steps to determine whether substrate-advance compensation will help you.
In general, substrate-advance calibration is recommended when you see print-quality problems related to paper advance, or when you define a new substrate.
While printing, you can view and change the substrate-advance compensation of the currently loaded substrate at any time from the Internal Print Server by selecting the print job and then the Printing Adj. button, or by selecting Printer > Printing adjustments.
Alternatively, you can open the dialogue from the Print adjustment button in the Internal Print Server, available under the Cancel All button on the left of the screen.
If you prefer the print quality after changing the figure in the Advance field, press the Apply button, and thereafter your preferred substrate-advance compensation will always be used for that particular substrate type. The selected value does not have to be the same for all substrates.
If you are using a generic substrate preset, you are recommended to clone the preset (Substrate > Clone) and work with that before adjusting the advance compensation, so as not to alter the generic preset. See Edit a substrate presetEdit a substrate preset.
The substrate-advance sensor may not work correctly if it is dirty. See Clean the substrate-advance sensorClean the substrate-advance sensor.
If the sensor was dirty, after cleaning it the advance compensation already calculated may not be valid, so you are recommended to set the advance compensation for this substrate to zero and check that the advance is correct. If the advance is still not accurate, follow the advance compensation process, bearing in mind that the sensor is not dirty and probably your substrate type is not compatible with it.

Substrate-advance test print

The substrate-advance test print can help you to adjust the substrate advance more accurately. In the Internal Print Server, select Printer > Advance calibration. The printer prints several repetitions of a special numbered pattern that help you to apply the correct substrate-advance adjustment. Locate the pattern in the center of the substrate.
The calibration pattern consists of several numbered columns.
Locate the lightest of the columns and enter its number as the advance parameter for the Printer > Printing adjustments dialog. The value chosen in this example should be −3.
