Abstract
A method for ink jet printing includes moving one or more receivers along a printing pass, ejecting ink drops from a first ink jet print head on a first receiver region of the one or more receivers in the printing pass, ejecting ink drops from a second ink jet print head on a second receiver region of the one or more receivers in the printing pass, and providing maintenance to the first ink jet print head while the second ink jet print head ejects ink drops on the first receiver region or the second receiver region.
Claims22
A method for ink jet printing, comprising:
- moving one or more receivers along a printing pass;
- ejecting ink drops from a first ink jet print head on a first receiver region of the one or more receivers in the printing pass;
- ejecting ink drops from a second ink jet print head on a second receiver region of the one or more receivers in the printing pass;
- and
- providing maintenance to the first ink jet print head while the second ink jet print head ejects ink drops on the first receiver region or the second receiver region.
A method for printing an ink image on a receiver, comprising:
- moving one or more receivers along a printing pass;
- receiving a first set of digital data by a first ink jet print head;
- ejecting ink drops from the first ink jet print head on a first receiver region of one or more receivers in the printing pass in response to the first set of data;
- receiving a second set of digital data by a second ink jet print head;
- ejecting ink drops from the second ink jet print head on a second receiver region of one or more receivers in the printing pass in response to the second set of data;
- altering the first set of digital data sent to the first ink jet print head in response to a maintenance call to the first ink jet print head;
- altering the second set of digital data sent to the second ink jet print head in response to the maintenance call to the first ink jet print head;
- and
- providing maintenance to the first ink jet print head while the second ink jet print head ejects ink drops on the first receiver region or the second receiver region.
A method for ink jet printing, comprising:
- moving one or more receivers along a printing pass;
- ejecting ink drops from a first group of ink jet print heads on a first receiver region of the one or more receivers in the printing pass;
- ejecting ink drops from a second group of ink jet print heads on a second receiver region of the one or more receivers in the printing pass;
- and
- providing maintenance to at least one ink jet print head in the first group of ink jet print heads while the rest of the ink jet print heads in the first group of ink jet print heads eject ink drops on the first receiver region and the second group of ink jet print heads eject ink drops on the second receiver region.
An ink jet printing apparatus, comprising:
- a first ink jet print head configured to eject ink drops on a first receiver region of one or more receivers;
- a second ink jet print head configured to eject ink drops on a second receive region of one or more receivers;
- and
- a first maintenance station configured to provide maintenance to the first ink jet print head while the second ink jet print head ejects ink drops on the first receiver region or the second receiver region.
