An example apparatus includes a conveyor. The apparatus also includes a first developer unit. The first developer unit is to concentrate first printing liquid. The first developer unit also is to deliver the first printing liquid to the conveyor. The apparatus also includes a second developer unit. The second developer unit is to concentrate second printing liquid. The second developer also is to deliver the second printing liquid to the conveyor to form a thick layer of printing liquid comprising the first and second printing liquid.

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 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.

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 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.

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.

A focusable imaging laser otoscope for performing laser surgery without the need for anesthesia, The apparatus includes a housing, an end member movably disposed within the housing, an imaging device attached to the housing for producing an image of a target area, an illuminating system attached to the housing for illuminating the target area, a speculum having a longitudinal axis and detachably attached to the end member, an optical system attached to the housing and having a main optical axis coaxial with the longitudinal axis of the speculum, for directing a surgical and/or an aiming laser beam from a laser source through the housing and the speculum to strike the target area and for directing image forming light rays to project an image of the target area onto the imaging device such that when the image of the target area is focused, the surgical laser beam and/or aiming laser beam are also focused on the target area, and a focusing assembly attached to the housing and to the end member for adjustably moving the end member and the speculum relative to the housing to focus the image of the target area. The otoscope may also be constructed without a focusing assembly, in which case the speculum may be detachably attached to the housing and the focusing is achieved by selecting an appropriate speculum from an available plurality of specula. The otoscope may also include a sensor system for indicating penetration of the target area. The sensor system may also automatically shut off the surgical laser after penetration of the target area.
