Printer capable of preventing drying of nozzle and control method thereof

摘要

A printer that prevents the drying of nozzles of an unused micro injecting device in an inkjet printer provided with a plurality of micro injecting devices, during printing, and a control method thereof. The object of this invention is to prevent drying of nozzles without moving the micro injecting device to a maintenance location and spraying a small amount of ink during a printing operation. The printer includes a plurality of micro injecting devices provided with a plurality of nozzles that receive nozzle drive data to drive the nozzles and spray ink; a plurality of micro injecting device drivers that provide the nozzle drive data for controlling the spraying of the nozzles and making the ink inside the nozzles move up and down; a carriage that is mounted with the plurality of micro injecting devices and reciprocates side to side above the paper; a control section that drives the unused micro injecting device among the plurality of micro injecting devices to make the ink move up and down. Accordingly, nozzle drying is prevented without moving the micro injecting device to a maintenance location and spraying a small amount of ink during a print operation.
