Patent ID: 8562104

Claim:
A maintenance system for a printhead, the system comprising: a support frame; a wiper module supported by the support frame, the wiper module comprising a porous roller for rotatably contacting the printhead to absorb fluid and particulates from the printhead, a non-porous roller in rotatable contact with the porous roller to transfer the absorb fluid and particulates from the porous roller, and a scraper in contact with the non-porous roller to remove the transferred fluid and particulates from the non-porous roller during said rotation; a lift mechanism for lifting the wiper module from the support frame to position the porous roller against the printhead; and a rotation mechanism for rotating the porous and non-porous rollers so that the porous roller rotates against the printhead and the non-porous roller is rotated against the porous roller and the scraper.
