Substrate-advance calibration, Calibration procedure, IMPORTANT

Page 103 highlights

Substrate-advance calibration 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 the substrate is loaded, the substrate-advance sensor checks the substrate and decides whether it can be adjusted automatically or not. If not, the automatic adjustment is disabled. The printer is configured from the factory with a generic preset for the sensor, calibrated for generic substrates. To improve substrate-advance performance for each substrate, HP recommends adjusting the substrate advance for each specific preset. If you want to adjust several substrates, this must be done for each preset. Substrate-advance calibration can help you to adjust the substrate advance more accurately. In the Internal Print Server, click Substrate > Advance calibration. The printer prints several repetitions of a special numbered pattern that help you to apply the correct substrate-advance adjustment. NOTE: The printheads should be correctly aligned before calibration, and the substrate-advance sensor should be clean. Otherwise, you may need to repeat the calibration after cleaning the sensor and aligning the printheads. See Clean the substrate-advance sensor on page 134 and Align the printheads on page 89. Calibration procedure NOTE: Substrate-advance calibration is not available for generic substrates. If you want to calibrate such a substrate, you will have to clone the generic preset and then calibrate the clone. 1. Load the substrate that you intend to calibrate. 2. In the Internal Print Server, click Substrate > Advance calibration. 3. Click Print calibration plot. The printer starts to print. 4. Enter the last eight values from the diagnostic plot. Select the lightest column and enter the corresponding value. Follow the instructions on the screen. TIP: If the plot shows two possible values (two continuous columns), the value to use is the average of the two. For example, if the plot indicates that the value could be +2.0 or +3.0, you can use +2.5. 5. Click Save to complete the calibration. Every time this preset is loaded, the printer will apply this calibration result. NOTE: The calibration obtained is only usable with the loaded substrate type. IMPORTANT: The calibration value cannot be used on another printer. If you intend to use the same substrate on multiple printers (even of the same model), you should go through the complete process on each printer. ENWW Substrate-advance calibration 97

Substrate-advance calibration
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 the substrate is loaded, the substrate-advance sensor checks the
substrate and decides whether it can be adjusted automatically or not. If not, the automatic adjustment is
disabled.
The printer is configured from the factory with a generic preset for the sensor, calibrated for generic substrates.
To improve substrate-advance performance for each substrate, HP recommends adjusting the substrate
advance for each specific preset. If you want to adjust several substrates, this must be done for each preset.
Substrate-advance calibration can help you to adjust the substrate advance more accurately. In the Internal Print
Server, click
Substrate
>

. The printer prints several repetitions of a special numbered pattern
that help you to apply the correct substrate-advance adjustment.
NOTE:
The printheads should be correctly aligned before calibration, and the substrate-advance sensor should
be clean. Otherwise, you may need to repeat the calibration after cleaning the sensor and aligning the
printheads. See
