Abstract
A composite wiper assembly is provided for cleaning ink residue from an inkjet printhead in an inkjet printing mechanism. The composite wiper has a wiper blade with a first portion of a first elastomeric material, and a second portion of a second elastomeric material different from the first elastomeric material. The wiper blade may also have a third portion of a third elastomeric material different from the first elastomeric material and different from the second elastomeric material. The composite structure of the wiper blade allows the materials of the different portions to be tailored to best serve the function of a particular portion. An inkjet printing mechanism having such a composite wiper is also provided.
