发明名称 Wiper for inkjet printhead nozzle member
摘要 A wiper according to the invention comprises two or more wiper blades arranged one behind the other in close proximity, where the two or more wiper blades are different from one another so as to have slightly different wiping swaths. The resulting wipers greatly increase the allowable alignment tolerance between the wiper and the nozzle member of a printhead, especially if the printhead is of the kind having raised adhesive beads dispensed near the ends of the nozzle member. In one embodiment, two different size wiper blades, arranged one behind the other, have slits formed near the ends of the wiper blades. The slits mechanically decouple those end portions of the wiper blades which ride over the adhesive beads from the remaining portions of the wiper blades to keep the remaining portions of the blades in contact with the nozzle member.
