Abstract

The invention provides an ink jet printer for inhibitting dirt such as ink attached on a cleaning component attach on a print head again and keeping the print quality. The ink jet printer comprises a doctorblade (75) is used for scraping surplus ink attached on the nozzle surface of the print head (111); a cleaning pad portion (70) of the cleaning doctorblade (75); a replacing detection device for detecting replacement of the cleaning pad portion (70). When detecting the replacement of the cleaning pad portion (70), the cleaning pad portion (70) cleans the doctorblade (75) in long time.

Description

technical field [0001] The present invention relates to an inkjet printer equipped with a cleaning device for removing ink adhering to a nozzle surface of a print head. Background technique [0002] In an inkjet printer, in order to maintain good printing quality, a cleaning device for removing excess ink adhering to the nozzle surface of the print head is indispensable. For example, Japanese Patent Laid-Open No. 2007-111860 (hereinafter referred to as the prior application) discloses an inkjet printer that slides and wipes the nozzle surface of the print head with a plurality of blades arranged on a belt to remove At the same time as excess ink or the like adhering to the nozzle surface, the blade is pressed against a cleaning member (cleaning pad) to remove the ink adhering to the blade. [0003] In the inkjet printer disclosed in the previous application, no matter whether the cleaning member is an unused new product or a used old product, the scraper blade will be press...
