Abstract:
1. An inkjet printer, comprising: a print head configured to move in a main scanning direction for ejecting ink from a nozzle; a wiper blade configured to move in a direction intersecting with the main scanning direction for wiping a nozzle surface of the print head on which the nozzle is formed, wherein the wiper blade has an effective wiping portion for effectively wiping the print head, wherein the nozzle surface has a wiping area to be wiped by the effective wiping portion, which is determined in advance in the main scanning direction, the wiping area being divided into a plurality of sections each having a width of the effective wiping portion and being partially overlapped with one another in the main scanning direction, wherein, when the nozzle surface of the print head is wiped by the wiper blade, the print head moves in the main scanning direction and the effective wiping portion is arranged at a wiping position corresponding to any one of the plurality of sections, and the print head is wiped at least twice while the wiping position is changed, to thereby wipe all portions within the wiping area by the effective wiping portion, and wherein, when the nozzle surface is wiped by the wiper blade, one of the plurality of sections different from one of the plurality of sections previously wiped is wiped; storage means for storing, when the nozzle surface is wiped by the wiper blade, the one of the plurality of sections previously wiped by the wiper blade; and calculation means for calculating a next wiping position based on the previously wiped position stored in the storage means.
