| 20100231635 | System And Method For Evaluating And Correcting Image Quality In An Image Generating Device - A system evaluates image quality in an image generating system in a manner that accounts for the interaction of the calibration tools used to evaluate and correct image quality in the image generating system. The system includes a test pattern generator configured to generate an image with an image generating system, an image capture device configured to generate a digital signal corresponding to the generated test pattern, an image evaluator configured to process the digital signal to detect and correct anomalies detected in the generated test pattern, a plurality of calibration tools, each calibration tool being comprised of at least one test pattern, at least one set of detection criteria, and at least one set of anomaly correction parameters, and a controller configured to select the calibration tools for operation of the test pattern generator and the image evaluator in accordance with a predetermined sequence that attenuates changes arising from application of correction parameters of one calibration tool upon a later selected calibration tool. | 09-16-2010 |
| 20100232652 | System And Method For Adjusting Operation Of Printheads In An Ink Printing Device - A method evaluates image quality in an ink printing system and generates data values for altering the operation of the ink printing system. The method includes generating an ink image on an ink image receiving member that corresponds to a digital image stored in the ink printing system, generating a scanned image signal corresponding to the ink image, generating firing signal waveform adjustments and image data adjustments with reference to the scanned image signal corresponding to the ink image, and operating a printhead in an ink imaging system with reference to the firing signal waveform adjustments and the image data adjustments. | 09-16-2010 |
| 20100277540 | Method for Calibration - A method of operating a printhead of an imaging device includes actuating a plurality of ink jets of the printhead to emit drops of ink onto an image receiving surface in accordance with a test pattern. The test pattern includes full pixel density areas and half pixel density areas that alternate in a process direction. Distances in a process direction between drops of the full pixel density areas and drops of the half pixel density areas in transition regions of the test pattern are then measured. The measured process direction distances are then correlated to a graininess level for the printhead. | 11-04-2010 |
| 20100277557 | Segmented Ink Stick - A method facilitates insertion of a segmented ink stick into an ink feed system of a phase change ink jet printer. The method includes bending of a flexible strand between ink stick segments during insertion of the ink stick segments and then straightening the flexible strand to orient the ink stick segments in the ink feed system. | 11-04-2010 |

| 20100026741 | USER ADAPTABLE INK STATUS CONVEYANCE SYSTEM - An ink status conveyance system comprises a maximum monitored ink level sensor operable with respect to an ink source for holding a supply of ink and delivering the ink to a printhead. The ink level sensor is configured to detect when an available amount of ink in the ink source corresponds to an ample ink level. A notification controller is configured to track the available amount of ink in the ink source between an ample ink level and an ink out level. A user interface is configured to enable a user to designate a low ink notification set point for the ink source at any ink level between the ample ink level and the ink out level. The notification controller is configured to compare the user designated low ink notification set point to the available ink volume value to generate a low ink notification when the available ink volume value corresponds to the user designated low ink notification set point. | 02-04-2010 |

| 20080218569 | Multi-position interlocking ink stick - An ink stick comprises an ink stick body having first and second opposed ends. A first interlocking face on the first end and a first interlocking face on the second end have complementary nesting shapes and are oriented to allow the first interlocking face of an end of the ink stick body to nest with a first interlocking face of an end of an adjacent ink stick when in a linear section of a feed path of an ink delivery system. A second interlocking face on the first end and a second interlocking face on the second end have complementary nesting shapes and are oriented to allow the second interlocking face of the ink stick body to nest with a second interlocking face of an end of an adjacent ink stick when in a non-linear section of the feed path. | 09-11-2008 |
| 20080218572 | Solid ink stick with reversible keying and interlocking features - An ink stick for use in an ink delivery system of a phase change ink imaging device comprises an ink stick body having first and second opposed end surfaces and first and second opposed lateral side surfaces. The ink stick body is rotationally symmetric about a vertical central axis of the ink stick body. The ink stick body includes an interlocking face on the first end surface and a complementarily shaped interlocking face on the second end surface. A key is on each of the first and second side surfaces. The keys of the first and second side surfaces are similarly shaped. The key on the first side surface and the key on the second side surface are rotationally symmetrically positioned with respect to each other about the vertical central axis. | 09-11-2008 |
| 20090128591 | System and method for measuring a supply of solid ink in a solid ink printer - A solid ink printer includes a solid ink measurement system that helps ensure an adequate supply of solid ink is in the feed channels delivering solid ink to a melting device within a printer. The solid ink measurement system includes a driving electrode mounted along a substantial length of a first structure of a first solid ink feed channel, a sensing electrode mounted along a substantial length of a second structure of the first solid ink feed channel, the sensing electrode being opposite and generally parallel to the driving electrode, an AC voltage source coupled to the driving electrode to generate an electrical field emitted from the driving electrode, and a capacitance measurement circuit coupled to the sensing electrode to receive an electrical signal induced in the sensing electrode by the electrical field generated by the driving electrode, the capacitance measurement circuit being configured to identify an amount of solid ink in the first feed channel that corresponds to the electrical signal received from the sensing electrode. | 05-21-2009 |
