LIQUID DROPLET INJECTION APPARATUS AND METHOD FOR RECOVERING NOZZLE OF LIQUID DROPLET INJECTION APPARATUS

摘要

A liquid droplet ejection apparatus including a head 1 in which a plurality of ink chambers 11 are aligned in one or both of an X direction and a Y direction, liquid droplets are ejected from nozzles 12, and printing is carried out in a print region of a recording medium based on print data, wherein the ink contains a dispersion medium and solid particles having higher specific gravity than that of the dispersion medium, and the liquid droplet ejection apparatus includes a flushing device that performs a flushing operation when the head 1 is present in a non-print region in such a manner that an amount of liquid droplets ejected from the nozzle 11b placed at an end portion in an alignment direction becomes larger than an amount of liquid droplets ejected from the nozzle 11a placed in a central portion in the alignment direction.

主权项

1. A liquid droplet ejection apparatus comprising a head in which a plurality of ink chambers to which an ink is supplied are aligned in one or both of an X direction and a Y direction, liquid droplets are ejected from nozzles provided in accordance with the ink chambers, and printing is carried out in a print region of a recording medium based on print data,
wherein the ink contains a dispersion medium and solid particles having higher specific gravity than that of the dispersion medium, and the liquid droplet ejection apparatus comprises a flushing device that performs a flushing operation for continuously ejecting liquid droplets from the nozzles when the head is present in a non-print region where the printing is not performed in such a manner that an amount of liquid droplets ejected from the nozzle placed at an end portion in an alignment direction becomes larger than an amount of liquid droplets ejected from the nozzle placed in a central portion in the alignment direction.
