ABSTRACT:
A rotary cleaning device for an ink jet type printer including a cylindrical supporting member having a flexible wiping blade thereon which is rotated in the motion path of printhead nozzles to facilitate cleaning ink and contaminants from the nozzle-containing face of the printhead is disclosed. The wiping blade runs along a helical path of the cylindrical supporting member to wipe the nozzles at an angle dependent upon the pitch of the helical path. The device may further include a sponge washing blade which runs in advance of the first wiping blade to wash the nozzle-containing face prior to wiping. Further, a cleaning device may be included to clean the blade(s) of any contaminants prior to the next rotation of the device to prevent removed ink or contaminants from further contact with the nozzle-containing face.
