ABSTRACT:
A method for maintaining the inkjet chip of an inject device. The inkjet device comprises an ink cartridge, a carrier, a wiper and a wiper stage. The carrier is used to load the ink cartridge. The wiper stage is used to load the wiper. The ink cartridge contains ink and has an inkjet chip. The inkjet chip has at least a set of inkjet nozzles. The method comprises the steps of: (a) relatively moving the carrier onto the wiper stage to locate the wiper to a position where the wiper can wipe the inkjet chip; (b) spraying the ink contained in the ink cartridge onto the wiper to moisturize the wiper; and (c) relatively reciprocating the wiper stage and the carrier to make the wiper wipe the inkjet chip.
