IPC: B41J2/185
Filed: 2002-07-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inkjet printer capable of suppressing consumption of ink for preliminary ejection, and to provide a method for recovering ejection state of a recording head.  <P>SOLUTION: The inkjet printer 1 comprises a recording head 8 having a plurality of ejection nozzles, and a cleaning blade for wiping off ink adhering to the ejection nozzles and performs preliminary ejection for removing ink being pushed into the ejection nozzles when ink is wiped off by means of the cleaning blade wherein preliminary ejection conditions are set based on the position of each ejection nozzle with respect to the recording head 8. Difference in the ink supply path from the ink tank to each ejection nozzle is based on the position of each ejection nozzle with respect to the recording head 8. Consequently, each ejection nozzle can perform preliminary ejection under optimal conditions when preliminary ejection conditions are set depending on the position with respect to the recording head 8 and ink consumption can be reduced.  <P>COPYRIGHT: (C)2004,JPO
