HP Designjet T1120 Printer series - Manual (Page 159)

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 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 firmware, the paper advance calibration values are
reset to factory default, see Update the firmware on page 131 .
CAUTION: Transparent papers and films must be calibrated using Image Quality Maintenance menu
icon , then Paper advance calibration > Adjust paper advance, from step four in the Recalibrating
the paper advance procedure.
