Abstract
A maintenance method is provided for a discharging head in which multiple discharging portions are arranged in line. The maintenance method includes the steps of performing an operation of continuously discharging droplets from one discharging portion or a plurality of unadjacent discharging portions, and repeating the operation for one discharging portion or a plurality of discharging portions adjacent to the previous discharging portion or the previous discharging portions in a predetermined direction.
Claims15
A maintenance method for an ink discharging head in which multiple discharging portions are arranged in a line, the method comprising:
- performing an operation of sequentially discharging droplets from a plurality of adjacent discharging portions in a predetermined direction toward a region of the discharging head which does not generate printed data at a side thereof.
A maintenance device for a discharging head in which multiple discharging portions are arranged in a line, wherein the maintenance device controls a head driving unit during a maintenance operation for the discharging head so as to perform an operation of sequentially discharging in a predetermined direction toward a region of the discharging head which does not generate printed data at a side thereof.
A droplet discharging apparatus comprising:
- a discharging head in which multiple discharging portions are arranged in a line;
- a head driving unit configured to drive the discharging head;
- a maintenance unit configured to perform an operation of sequentially discharging droplets in a predetermined direction toward a region of the discharging head which does not generate printed data at a side thereof.
A discharging head comprising:
- multiple discharging portions arranged in a line;
- a discharging region in which discharging portions used for printing are arranged;
- and
- a trap region in which discharging portions that are not used for printing are arranged at a side of the discharging head, the trap region being provided at one end or both ends of the discharging region, and configured to trap a foreign substance or a bubble moved by performing an operation of sequentially discharging droplets from in a predetermined direction toward a region of the discharging head which does not generate printed data at a side thereof.
A computer program stored in an electronic memory of a microprocessor controlled system for causing maintenance operation of an ink discharging head in which multiple discharging portions are arranged in a line, wherein execution of the computer program instructions causes the microprocessor controlled system to perform:
- the sequential discharge of droplets from discharging portions in a predetermined direction toward a region of the discharging head which does not generate printed data at a side thereof.
