In an LEP printer having a wiper blade for wiping a photo imaging plate, the photo imaging plate may include a PIP foil with a trailing edge having a zone of a roughening pattern which includes notches that are inclined with respect to a contact line of the wiper blade. The zone of roughening pattern is confined between two opposite margins lacking any roughening.

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.

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.

Hard image forming apparatuses and methods are described. According to one arrangement, a hard image forming apparatus includes an imaging member comprising a surface, a development system configured to provide a marking agent to the surface of the imaging member to form developed images upon the surface of the imaging member which correspond to latent images formed using the surface of the imaging member, and a transfer system configured to transfer the developed images from the surface of the imaging member to media. The arrangement further includes a contamination removal device configured to remove contamination material from the surface of the imaging member, and a control system configured to control the contamination removal device to contact the surface of the imaging member to remove the contamination material from the surface of the imaging member at a first moment in time and to space the contamination removal device from the surface of the imaging member at a second moment in time where the contamination removal device does not remove the contamination material from the surface of the imaging member.

摘要:
A system and method for determining LEP ink conductivity are provided. A pair of electrodes is arranged to define a narrow gap there between. A non-conductive propeller rotates within the gap and causes liquid ink to flow over respective planar surfaces of the electrodes. The rotating propeller further prevents the accumulation of ink sludge on the planar surfaces of the electrodes within the gap. Electrical current is conducted between the electrodes. The electrical current is measured and the conductivity value of the ink determined there from.
