Abstract
A multi-function printer and a method for calibrating the multi-function printer is disclosed The calibrating method for a printer comprises printing a calibration pattern on a medium by the printer; obtaining a scanned image of the calibration pattern on the medium printed by the printer; comparing the scanned image against the calibration pattern; detecting defects of the scanned image; and if the defects exceed an pre-determined value, adjusting print settings of the printer according to the defects of the scanned image.
Claims20
A calibrating method for a printer, the calibrating method comprising:
- printing a calibration pattern on a medium by the printer;
- obtaining a scanned image of the calibration pattern on the medium printed by the printer;
- comparing the scanned image against the calibration pattern;
- detecting defects of the scanned image;
- and
- if the defects exceed an pre-determined value, adjusting print settings of the printer according to the defects of the scanned image.
A multi-function printer (MFP), comprising:
- a printer unit adapted to print a calibration pattern on a medium;
- a scanner unit adapted to obtain a scanned image of the calibration pattern on the medium printed by the print unit;
- an image processing unit adapted to compare the scanned image against the calibration pattern, and to detect defects of the scanned image;
- and
- a setting unit adapted to adjust print settings of the printer unit if the defects of the scanned image exceeds a pre-determined value.
A multi-function printer (MFP) controlling method, wherein the MFP comprises a printer unit and a scanner unit, the multi-function printer (MFP) controlling method comprising:
- the printer unit printing a calibration pattern on a medium;
- the scanner unit scanning an image of the calibration pattern on the medium printed by the printer unit;
- comparing the scanned image against the calibration pattern;
- detecting defects of the scanned image;
- and
- if the defects exceed a pre-determined value, adjusting print settings of the printer unit according to the defects of the scanned image.
