Abstract
A multi-finned wiping system is provided for wiping an inkjet printhead that accumulates ink residue when used in an inkjet printing mechanism. A service station supports a wiper that contacts and wipes ink residue from the printhead. The service station also supports a cleaner that contacts and cleans the wiper. Either the wiper or the cleaner maybe constructed is of a resilient material comprising plural fins arranged to define an interstice between adjacent fins to capture the ink residue in the interstice. Interaction of the wiper and cleaner during the cleaning process pumps ink residue from the interstice to ready the fins for the next cleaning cycle. An inkjet printing mechanism having such a finned wiping system is also provided, along with a method of wiping accumulated ink residue from an inkjet printhead installed in an inkjet printing mechanism.
