Abstract
According to one embodiment, an inkjet recording device includes a cleaning member which faces a nozzle surface of an inkjet head and moves along a row of nozzles, a control device which controls ones of the nozzles to partially discharge ink, the ones of the nozzles positioning in an area which the cleaning member faces when the cleaning member moves, and an ink retaining part which retains the ink between the cleaning member and the nozzle surface of the inkjet head which faces the cleaning member.
Claims19
An inkjet recording device comprising:
- an inkjet head which comprises a row of nozzles arranged in a predetermined direction in a nozzle surface and which discharges ink from the row of nozzles;
- a cleaning member which faces the nozzle surface of the inkjet head and moves along the row of nozzles;
- a control device which controls ones of the nozzles to partially discharge the ink, the ones of the nozzles positioning in an area which the cleaning member faces when the cleaning member moves;
- and
- an ink retaining part which retains the ink between the cleaning member and the nozzle surface of the inkjet head which faces the cleaning member.
An inkjet recording device comprising:
- an inkjet head which comprises a row of nozzles arranged in a predetermined direction in a nozzle surface and which discharges ink from the row of nozzles;
- a cleaning member which faces the nozzle surface of the inkjet head
- a slider which mounts the cleaning member and moves the cleaning member along the row of nozzles;
- a control device which supplies the inkjet head with a drive signal when the cleaning member is moved, to control ones of the nozzles to partially discharge the ink, the ones of the nozzles positioning in an area which the cleaning member faces;
- and
- a collection device which collects the ink subjected to cleaning by the cleaning member.
An inkjet recording method comprising:
- making a cleaning member face a nozzle surface of an inkjet head which discharges ink from a row of nozzles arrayed in a predetermined direction in the nozzle surface;
- cleaning the nozzle surface by moving the cleaning member along the row of nozzles;
- and
- supplying the inkjet head with a drive signal when the cleaning member is moved, to control ones of the nozzles to partially discharge the ink, the ones of the nozzles positioning in an area which the cleaning member faces.
A cleaning device for an inkjet recording device, comprising:
- a cleaning member comprising an ink-philic part facing a part of a nozzle surface of an inkjet head which comprises a row of nozzles arranged in a predetermined direction in the nozzle surface and is capable of discharging ink from the row of nozzles, the cleaning member being movable along the row of nozzles while maintaining a predetermined gap between the nozzle surface and the ink-philic part;
- and
- a control device which makes ones of the nozzles of the inkjet head discharge the ink into the gap between the nozzles surface and the cleaning member, thereby forming an ink retaining part and a meniscus at edges of the cleaning member, and which simultaneously moves the cleaning member along the nozzle surface.
