Abstract: Prioritizing a printing system's basic processing resources includes providing a job contention manager (JCM) that adds a first basic job resource to queues of each basic resource which a first video capability requires to perform a first sub-job. The first basic job resources are ready for processing if they are at the top of all of the queues, of all the basic resources, required by the first video capability. The JCM adds a second basic job resource sub-job to queues of each basic resource which a second video capability requires to perform the first sub-job. The second basic job resources, are ready for processing after the first basic job resource, if the first and second basic job resources in the queue are submitted by the same job service and if the second basic job resource is for the same sub-job as the first basic job resource's sub-job.

Abstract: An apparatus and process for applying an electrical charge to a photoreceptor wherein a bias charge roll member is situated in contact or in close proximity with a surface of member to be charged such as a photoreceptor. The bias charge roll member is supplied with an electrical bias having a rectified AC waveform onto which a DC bias is superimposed after the waveform has been rectified. The result is the ability to raise the voltage potential of the photoreceptor with less pulse voltage and, more particularly, to increase the voltage potential of the photoreceptor along as if only DC voltage were applied far above what is possible in the prior art. Among the advantages of the invention is the ability to minimize photoreceptor wear at higher levels of photoreceptor charge since the DC-offset bias enables the second Paschen threshold to be avoided for higher levels of the photoreceptor charge.

Abstract: Initial setup of image to sheet (IOS) or image to paper (IOP) registration in a printing device such as, for example, an electrographic printer, is accomplished in a single step that uses an initial set of measurements to determine and correct each of the independent registration errors, including image squareness/ROS skew, image skew/paper skew, lateral magnification, process magnification, lateral direction IOS or IOP position, and process direction IOS or IOP position simultaneously. A set of algorithms is used to perform a series of geometrical transformations to determine each of the six errors affecting IOS or IOP registration.

Abstract: Light emitting diode (LED) bar systems have large surface areas and extensive cabling that carry high frequency clocks and data. As the process speeds increase, the higher clock and data rates become an electromagnetic interference (EMI) problem. As the U.S. federal government restricts EMI emissions, many have turned to shielding techniques. However, a spread spectrum technique now may also reduce peak EMI amplitudes by distributing the EMI energy over a range of frequencies. The pixel data may be clocked into a LED bar system with a varying frequency to spread the energy over the range of the modulation. The same total energy is still emitted from the system, but the peak energy at any particular frequency is reduced.

Abstract: A set of ink sticks for a phase change ink jet printer includes a plurality of ink sticks. Each ink stick is formed of a three dimensional ink stick body with a perimeter. Each of the ink stick bodies has one or more key elements formed in its perimeter. Each of the key elements has a uniform shape and size. The key elements are in different positions on the perimeter of each ink stick, and particularly the key elements of some of the ink sticks are on a different side of the ink stick than are the key elements on others of the ink sticks in the set. Corresponding keys on the openings through which the ink sticks are inserted into their appropriate feed channel exclude ink sticks of the set that do not have the appropriate perimeter key element.

Abstract: A method of diagnosing a printer includes performing a series of parametric tests on the printer at the time of manufacture to generate a set of baseline values for the printer and storing the baseline results. The baseline results may be stored remotely or with the printer, or both. A set of maximum parametric test variations for the printer type is generated, such that each maximum parametric test variation is associated with a particular printer fault event. At the time of a suspected printer fault, the same parametric tests are performed and a set of suspected fault values generated. The difference between the suspected fault value and the baseline value is calculated for each parametric test. If the difference for a particular parametric test is greater than the maximum parametric test variation for that particular parametric test, the print fault event associated with the parametric test value may be indicated.

Abstract: The present invention provides an image-forming device that can record an image onto a rewritable image recording medium. Prior to recording a predetermined image, the medium is set and a test image for measuring the density is recorded thereon. When the density is determined to be within an allowable range, the predetermined image is recorded under certain image recording conditions and then discharged to a discharging tray. However, should the density be outside the allowable range, the conditions are changed and another test image is recorded to the medium. If after repeated density measurements the density is not within an allowable range, the device determines that the medium is defective and discharges it to an error tray.
