International Classification:

B41J 201

US Classification:

347 14, 347 17

Abstract:

The invention provides a printing apparatus for printing an image having a spatial resolution onto a print medium. The printing apparatus includes a printhead having a plurality of printing elements for ejecting ink droplets having a mass onto the print medium, and a temperature sensor for sensing a temperature of the printhead, producing a temperature signal. The apparatus also includes a media sensor for determining what type of print medium is loaded in the printer and producing a print medium signal based on the type of print medium installed in the printer. A plurality of heating devices are located adjacent the printhead for adjusting the temperature the printhead. The apparatus includes a printer controller for receiving the temperature signal from the temperature sensor and the print medium signal from the media sensor, and determines the ink temperature based on the print medium signal, and activates the heating devices to maintain the temperature of the printhead within a desired temperature range that is dependent upon the print medium signal.

Abstract:

An apparatus for a laser transmission welding process for attaching a synthetic filter material to a filter tower frame in an ink jet printer cartridge. The apparatus includes a laser beam source and a filter clamping fixture containing a base, slide rods attached on first ends thereof to the base, an optics support plate attached to second ends of the slide rods, a movable platform for holding an ink cartridge slidably disposed on the slide rods between the base and the optics support plate, a platform moving device for translating the platform to and from a laser welding position, a laser beam transparent plate suspended by support legs from the optics support plate to a position between the movable platform and the optics support plate.

US Classification:

399 44, 399 97, 399299, 399302, 399308, 399313, 347112

Abstract:

An improved color EP (laser) printer is provided for use in high humidity conditions. A humidity sensing circuit determines if the print quality might be degraded due to environmental conditions, using a resistivity sensing circuit, or a humidity sensor. If the print quality would likely be degraded, the invention is able to enhance toner transfer by printing supplemental process black toner dots underlaying standard black toner dots at predetermined pixel locations in the bitmap of a print job. This assumes that the black printing station is the “last” station along the travel of the intermediate transfer member. Other colors could be used for the supplemental toner dots.

International Classification:

G03G 15/08

US Classification:

399281

Abstract:

The present invention relates to a device or method which may reduce starvation in the transfer of an image forming substance to a developing location within an image forming apparatus. The device may include a first roller having a surface which is capable of supplying an image forming substance to a developing location. A second roller may then be included having a surface in rotating contact with the first roller. The second roller is capable of supplying image forming substance to the first roller. The second roller may comprise foam having a specified porosity, electrical conductivity, and/or be configured to rotate in a desired direction and/or desired speed relative to the first roller.

International Classification:

G03G 15/06

US Classification:

399302, 399308

Abstract:

The present application is directed to methods and devices for controlling charge buildup on a toner image as the toner image passes through one or more transfer nips. Charge buildup may be reduced by laterally offsetting a transfer roller from a photoconductor drum. The transfer roller may be constructed of an essentially non-compressible conductive material. AC current may be used to generate an electrical field between the photoconductor drum and the transfer roller.

US Classification:

Abstract:

A system for tailoring a transfer nip electric field includes a transfer roll, a backup roll forming a transfer nip with the transfer roll, and a pre-nip roll positioned upstream from the transfer and backup rolls and the transfer nip such that a toner image-supporting transfer belt moving past the pre-nip, transfer and backup rolls separately makes contact with, wraps partially around, and rotates each of the rolls as a media sheet is fed into the transfer nip after first passing through a gap defined between the pre-nip and transfer rolls such that by presetting the position, geometry and charge of the pre-nip roll relative to the transfer and backup rolls and the transfer belt an electrical field at the transfer nip can be tailored for enhanced toner transfer from the transfer belt to the media sheet.

Abstract:

A toner transfer station of an electrophotographic imaging device employs a backup roll having an inner electrically grounded cylindrical metal base core and an outer surface layer disposed about the inner base core. The outer surface layer may be formed of a polyurethane elastomer material to provide a capacitive coating with a thickness greater than 15 microns, a dielectric constant less than 12 and a resistivity of less than 3. 00E+13 Ohm-cm.

International Classification:

G03G 15/16

US Classification:

399313

Abstract:

A transfer station for toner transfer in an electrophotographic imaging device includes an endless transfer belt transported about an endless path through the imaging device, a transfer roll adjacent one surface of the transfer belt, and a backup roll adjacent an opposite surface of the transfer belt opposite from the transfer roll such that the transfer roll and backup roll form a transfer nip effecting transfer of toner. For the purpose of improved overtransfer performance, an outer layer of a thin polymer coating is applied to at least one of the transfer belt and the rolls so as to be located within the transfer nip with transfer of toner. The polymer layer has a thickness from about 5 μm to about 200 μm, surface resistivity from about 1E08 to about 1E12 Ohm/cm and breakdown strength greater than 500 V.
