Liquid ejection device control method and liquid ejection device

A liquid ejection device control method for a liquid ejection device including

• a liquid ejection head having a nozzle surface in which a plurality of nozzle arrays is formed by a plurality of nozzles for ejecting liquid, the liquid ejection head being configured to record an image on a medium by ejecting liquid from the plurality of nozzles;
• a wiping section which has an absorbent member configured to absorb liquid, the wiping section being provided at a position adjacent to a support section supporting the medium, wherein
• the liquid ejection head is movable relative to the wiping section in a scanning direction and in a sub-scanning direction;
• and
• a pressurizing section provided outside the liquid ejection head, the pressurizing section configured to supply pressurized liquid to the liquid ejection head and pressurize liquid in the nozzles of each of the plurality of nozzle arrays;
• the nozzle arrays extend in the sub-scanning direction and are formed at predetermined intervals in the scanning direction;
• and
• the wiping section is set with, at different positions from each other, a wiping region in which the absorbent member wipes the nozzle surface of the liquid ejection head during movement in the sub-scanning direction of the liquid ejection head and a receiving region in which the absorbent member receives liquid discharged from the plurality of nozzle arrays,
• the control method comprising:
• performing flushing which includes:
• ejecting liquid from the plurality of nozzles of the nozzle array to overlap in the sub-scanning direction within the receiving region;
• and
• ejecting liquid from each of the plurality of nozzle arrays in the receiving region at intervals in the scanning direction that are smaller than the predetermined intervals;
• and
• performing pressurized discharge,
• the pressurized discharge including discharging liquid to an absorbent member by using the pressurizing section to pressurize liquid in a plurality of nozzles of the nozzle array, wherein
• when the flushing is performed, an ejection trace is formed on the absorbent member,
• when the pressurized discharge is performed, a pressurizing trace is formed on the absorbent member, and wherein
• in the scanning direction, a size of margin from an end of the absorbent member to the ejection trace is smaller than a size of margin from the end of the absorbent member to the pressurizing trace.
