Abstract (en)
A dual-blade wiper system (100; 100'; 100''; 130) for cleaning inkjet printheads (70, 72, 74, 76) in an inkjet printing mechanism (20) gives individual wiping attention to an orifice plate (160) through which ink-ejecting nozzles are formed with a "little-brother blade (110; 140)," while also wiping the entire printhead, including cheek regions (162) of the printhead adjacent the orifice plate (160), using a "big-brother blade (120; 150; 170)." Both blades (110, 120; 140, 150; 110, 170) are onsert molded to a spring steel support platform (102; 132) that carries the blades between rest and servicing positions. Several dual-blade assemblies may be formed on the platform, with all the wider big-brother blades aligned (100), or alternating with the narrower little-brother blades (100'), or a single unitary big-brother blade (100'', 170) may be used to wipe several printheads simultaneously. An inkjet printing mechanism (20) having such a dual-blade wiper system (100; 100'; 100''; 130) is also provided. <IMAGE>
