Abstract
A printer is operated to determine an attribute of a field of view of the scan sensor. A calibration test pattern is determined based on the field of view (e.g., size of the field of view relative to dimension of individual bar in pattern).
Claims15
A method for operating a printer, the method comprising:
- determining an attribute of a field of view of a scan sensor of the printer;
- determining a calibration pattern based on the attribute of the field of view;
- scanning a swath of the determined calibration pattern to generate a signal pattern output;
- determining, based at least in part on the signal pattern output, a print zone profile for the printer;
- and
- determining a calibration setting for the printer based at least in part on the print zone profile.
3 more elements
A printer comprising:
- a controller,
- an ink interface component including carriage and a print head;
- and
- a scan sensor;
- the controller to:
- determine an attribute of a field of view of a scan sensor of the printer;
- determine a calibration pattern based on the attribute of the field of view;
- determine a calibration setting for the printer using the calibration pattern;
- and
- calibrate, based on a signal pattern output, at least a print head of the printer for ink placement on a print media along at least an axis of a plane of the print media as the media is advanced.
7 more elements
A non-transitory computer-readable medium that stores instructions which, when executed by at least a processor of a printer, cause the printer to:
- determine an attribute of a field of view of a scan sensor of the printer;
- determine a calibration pattern based on the attribute of the field of view;
- and
- scan a swath of the determined calibration pattern to generate a signal pattern output;
- determine, based at least in part on the signal pattern output, a print zone profile for the printer;
- and
- determine a calibration setting for the printer based at least in part on the print zone profile.
