Patent number: 8876417Abstract: A paper sensor comprises a moveable grill. The paper sensor is arranged for location within an air flow in a printer, and comprises the grill as a paper-engaging body provided with a plurality of through holes such that air can flow freely through the grill. The grill is operable to move between a first position and a second position. The paper sensor is arranged so that in use a sheet of paper introduced adjacent the grill engages the grill and reduces the air flow through one or more of the holes in the grill, creating a pressure differential across the grill, that pressure differential causing the grill to move from the first position to the second position, and thereby indicating the presence of paper. A printer comprising a paper sensor, and a method of sensing paper is also disclosed.Type: GrantFiled: July 27, 2007Date of Patent: November 4, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Giries Kadis, Sharon Nagler, Gregory Brusilovski

Patent number: 8583021Abstract: A method of maintaining a photoconductive member of an image forming apparatus is disclosed. The method includes applying fluid to a photoconductive member to form an image thereon, transferring the fluid from the photoconductive member in the form of the image and providing sponge applicator fluid to respective sponge applicator units. The method also includes squeezing the sponge applicator units to remove at least a portion of the sponge applicator fluid therefrom and sequentially placing each one of the sponge applicator units in contact with the photoconductive member to cool and clean the photoconductive member.Type: GrantFiled: April 28, 2011Date of Patent: November 12, 2013Assignee: Hewlett_Packard Indigo B.V.Inventors: Giries Kadis, Wael Salalha, Shunit Petachia, Sharon Nagler, Marko Richter, Assaf Bendek, Roy Har-Tsvi
