Abstract
A printing apparatus includes a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets; a recovery unit that recovers an ejecting condition of nozzles of the printing head; and a control unit that determines whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controls a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.
Claims13
A printing apparatus comprising:
- a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets;
- a recovery unit that recovers an ejecting condition of nozzles of the printing head;
- and
- a control unit that determines whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controls a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.
A method for controlling a printing apparatus including a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets, and a recovery unit that recovers an ejecting condition of nozzles of the printing head, the method comprising:
- determining whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controlling a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method for controlling a printing apparatus including a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets, and a recovery unit that recovers an ejecting condition of nozzles of the printing head, the method comprising:
- determining whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controlling a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.
