20110279533MAINTENANCE SYSTEM HAVING TRANSLATABLE AND ROTATABLE WIPER AND CLEANER FOR PRINTHEAD - A maintenance system for a printhead is provided having a sled, a wiper module supported by the sled, a lift mechanism for lifting the wiper module from the sled the wiper module, a rotation mechanism, and a sliding mechanism for sliding the sled relative to the printhead. The wiper module has rotatable porous and non-porous rollers in contact with one another. The rotation mechanism rotates the porous and non-porous rollers so that the porous roller of the lifted wiper module rotates against the printhead and the non-porous roller rotates against the porous roller. The porous roller is configured to absorb fluid from the printhead during rotation and the non-porous roller is configured to clean the absorbed fluid from the porous roller. The sliding mechanism slides the sled so that the rotating porous roller is wiped across the printhead.11-17-2011

20130187980NOZZLE SURFACE WIPING APPARATUS AND DROPLET EJECTION APPARATUS - A nozzle surface wiping apparatus wipes a nozzle surface of a droplet ejection head while moving relatively with respect to the head. The apparatus includes: a band-shaped wiping web; a pay-out spindle which pays out the web; a take-up spindle which is rotated to take up the web; a pressing device which causes the web travelling between the pay-out spindle and the take-up spindle to be pressed against the nozzle surface; a drive roller around which the web travelling between the pressing device and the take-up spindle is wrapped, the drive roller being rotated to apply conveyance force to the web toward the take-up spindle; and a driving device which drives the drive roller and the take-up spindle in such a manner that a velocity at which the web is taken up by the take-up spindle is faster than a velocity at which the drive roller applies the conveyance force to the web.07-25-2013
20120019591IMAGE FORMING APPARATUS AND METHOD THEREOF - An image forming apparatus includes a fluid receiving member having fluid receiving cells in which the fluid receiving cells are configured to receive at least one of an ink repellant and an ink, a fluid ejector unit configured to eject the ink repellant to a first set of the fluid receiving cells, and an inking unit configured to apply the ink to a second set of the fluid receiving cells.01-26-2012
20130194346IMAGE FORMING APPARATUS - An image forming apparatus includes: a recording head with multiple nozzles on a surface of the recording head to discharge droplets, the surface with the nozzles facing in a horizontal direction or in a direction leaning upward or downward with respect to the horizontal direction, a wiper to wipe the surface with the nozzles of the recording head from top to bottom, a guide member attached to the recording head at the lower end of the surface with the nozzles, to have contact with the wiper, and a cleaning member attached to a main body of the apparatus to clean the guide member.08-01-2013
20120299994INK JET PRINTER WIPER BLADE - An ink jet printer wiper blade includes a base, and a blade plate extending from the base. The blade plate includes a support portion and a lead edge portion proximate to the support portion, the lead edge portion is configured for scraping waste ink. The blade plate comprises a plurality of elongate protrusions protruding from the support portion. The protrusions are configured for creating a Coanda effect to attract the scraped ink to the support portion.11-29-2012
