摘要： A method of operating a printer enables the mass of the ink drops ejected by the printheads in the printer to maintained in an optimal range without measuring the drop mass being ejected by the inkjets in the printheads. After calibration of the printheads, the printheads are operated with electrical signals having different peak-to-peak voltages. The number of inoperable inkjets for each printhead is determined from image data of the ejected ink on the image receiving member and the number of inoperable inkjets for each printhead is compared to a predetermined threshold. The peak-to-peak voltage for the electrical signals used to operate a printhead is adjusted with reference to the number of inoperable inkjets and the predetermined threshold.

摘要： An imaging device includes a substantially continuous web of media, and a web transport system configured to transport the continuous web along a web path. A print station is positioned along the web path and is configured to apply ink to the continuous web. A temperature leveling ink spreader is disposed along the web path downstream from the print station. The temperature leveling ink spreader includes a leveler roller including a heater configured to generate thermal energy to heat the leveler roller to a spreading temperature. The leveler roller is positioned to be partially wrapped by the continuous web to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being transported to equalize the temperatures of the web and ink on the web to within a predetermined range about the spreading temperature. The temperature leveling ink spreader includes a pressure roller positioned adjacent the leveler roller to form a spreading nip therebetween through which the continuous web is fed after the predetermined dwell time. The spreading nip is configured to apply a predetermined pressure to the continuous web and the ink thereon.

摘要： A method of operating a printer produces duplex images in print jobs including ink images to be printed to tabbed, hole-punched, and differently sized media sheets with improved throughput. The method synchronizes a media transport to insert a differently sized media sheet with reference to the type of media sheet, enabling the media sheet to contact a portion of the roller bearing substantially less release agent than the rest of the roller, minimizing release agent transfer to a second side of the media sheet.

摘要： A method enables an operator to detect misalignment of printheads that eject clear ink in an inkjet printer. The method prints a first test pattern with a first color of ink and then prints a second test pattern of clear ink on top of the first test pattern. The ink of the first and the second test patterns is then spread to enable the clear ink to be dispersed in interstitial spaces in the ink of the first color. An operator is then able to detect the spatial relationship of predetermined marks in the second test pattern to predetermined marks in the first test pattern. The predetermined marks of the first and the second test patterns are arranged to enable an operator to detect a misalignment distance and the inkjet printer uses the misalignment distance entered by the operator to adjust the alignment of the printheads that eject clear ink.

摘要： A method for calibrating in situ a plurality of printheads in an imaging device has been developed. Firing signals operate a plurality of printheads to form ink test patterns on an image receiving member. Reflectance measurements of light reflected from the test patterns and optical density measurements for a portion of the patterns formed by only one printhead in the plurality of printheads are used to adjust the firing signals and enable the printheads to print within a predetermined range about an average reflectance value and a predetermined optical density.

摘要： An inkjet printer has a printhead in which all of the inkjets are used for printing, but at a less than maximum available ejection output. When a failed inkjet is identified, the ejection throughput is increased for inkjets that print pixels in an at least two pixel neighborhood about a missing pixel, so the pixels to be printed by the failed inkjet are printed by inkjets that print pixels in the two pixel wide neighborhood.

摘要： A method improves transfer efficiency of ink images on an image receiving member that were formed with small ink drops. The method includes identifying image data that correspond to ink drops that have a mass less than a predetermined threshold and that fail to comingle with another ink drop ejected with reference to the image data, modifying the identified image data to generate ink drops that comingle with at least one other ink drop ejected with reference to the image data, generating firing signals for inkjet ejectors in a print head with reference to the image data and modified image data, and ejecting in response to the firing signals a plurality of ink drops from the inkjet ejectors for each identified image data to enable a coalesced ink drop to form on an image receiving surface that has a mass that is greater than the predetermined threshold.
