● Bad substrate advance with double horizontal lines Readjust the substrate advance (see Manual substrate-advance compensation on page 135). Calibrations specific to one substrate preset Some calibrations that the printer performs are specific to the substrate preset in use at the time the calibration was performed, and some are not. The calibrations that are specific to one substrate must be performed again if the substrate or preset is changed. Shown below are the calibrations, showing which ones are specific to one preset and which ones are not: ● Printhead alignment: This is applied to all presets and print modes. Usually, when switching from one substrate to another, there is no need to realign the printheads. However, if the printhead-to-substrate spacing has changed significantly (perhaps because of a change in substrate thickness), then the printheads should be realigned. ● Substrate-advance compensation: This is specific to each substrate preset. ● Color calibration: This is specific to each substrate preset.
