A method and apparatus for controlling a power supply. The system includes a power supply and a controller for outputting a command signal to regulate the operation of the power supply. The controller determines the command signal based on at least one error signal which is selected from a plurality of error signals based on a selection criterion.

Power supply control loop with multiple leveling modes

A fault handling algorithm processes a plurality of fault status signals from a sputtering system in a period of time to generate at least one command signal for affecting the operation of a power generator.

Control system for a sputtering system

A skewed substrate pixel array printing machine includes a frame; a printhead mounted to the frame for printing pixels onto a platen; a device for providing relative motion between the printhead and a platen; and a platen for printing thereon. The platen has a platen axis parallel to a direction of the relative motion between the printhead and the platen; and a rectangular area thereon for printing onto. The rectangular area importantly has an edge thereto that forms an image defect preventing first skew angle with the platen axis.

Skewed substrate pixel array printing machine

Disclosed is a recording sheet which comprises a substrate and an image-receiving coating situated on at least one surface of the substrate, said image-receiving coating being suitable for receiving images of an aqueous ink, said image-receiving coating comprising a poly(ethylene-vinyl alcohol-vinyl acetate) terpolymer, said terpolymer containing ethylene repeat units in an amount of from about 5 to about 20 mole percent, vinyl alcohol repeat units in an amount of from about 70 to about 85 mole percent, and vinyl acetate repeat units in an amount of from about 5 to about 20 mole percent.

Recording sheet for use with aqueous inks

A printing device having a print carriage assembly that reduces a carriage excursion along a carriage scan axis and/or reduces a width of a printing flat zone along a media feed axis, is disclosed. The print carriage assembly has a frame that traverses across a media along a carriage scan axis. The media travels along a media feed axis that is substantially perpendicular to the carriage scan axis. A first print cartridge subassembly includes a first base secured to the frame and a plurality of first print elements secured to the first base. Each of the first print elements includes a first nozzle array for ejecting an ink composition. The plurality of first print elements are spaced apart along the carriage scan axis and are offset along the media feed axis. A second print cartridge subassembly includes a second base secured to the frame and a plurality of second print elements secured to the second base. Each of the second print elements have a second nozzle array for ejecting an ink composition. The plurality of second print elements are spaced apart along the carriage scan axis and are offset along the media feed axis. The print carriage assembly reduces a carriage excursion along a carriage scan axis and/or reduces a width of a printing flat zone along a media feed axis.

Modular carriage assembly for use with high-speed, high-performance, printing device

A method and apparatus for removing dissolved air in ink and air bubbles or air pockets from ink passageways in ink jet printer cartridges by use of a permeable membrane tubing member positioned in the ink at a location adjacent the ink inlet of the printer's droplet ejecting printhead. The permeable membrane tubing member is connected to a vacuum source to diffuse air into the vacuum in the tubing member interior. The vacuum source may be by a direct connection to the printer's vacuum priming pump at its maintenance station, a separate vacuum pump, or a vacuum accumulator.

Air removal means for ink jet printers

A transparency for ink jet printing is enhanced for use as an ink jet recording medium by increasing the hydrophilicity of the coating formed on a transparent substrate. In one embodiment, the coating is subjected to a corona plasma discharge exposure to create changes in oxygen functionality at the coating surface resulting in increases in surface hydrophilicity. In another embodiment, the surface is exposed with UV radiation and ozone exposure for controlled periods of time. In both cases, the surface hydrophilicity is increased by generating highly reactive free radical oxygen (O.sup.-) which results primarily in increases in the oxygen functional groups C.dbd.O and COO.sup.-.
