摘要： A method of operating a printer enables a controller in the printer to operate electrical motors to move printheads in the printer for longer periods of time before maintenance is required. Each printhead in the printer is operatively connected to an electrical motor for movement of the printhead and the printheads are organized in groups with each group being operatively connected to an electrical motor for movement of the group. By selectively designating printheads as being moveable or fixed, electrical motors that fail to move a printhead can be taken out of operation and an electrical motor that moves the printhead group used instead to continue printing operations without requiring a service call for replacement of the failed motor.

摘要： A method enables an inkjet printing system to attenuate image noise in an image of a test strip obtained as print media bearing the test strip travels over a roller in the printing system. The method includes illuminating blank media as the media travels over a rotating member, generating electrical signals corresponding to light reflected by the blank media as the blank media travels over the rotating member, converting the electrical signals to image data of the blank media, printing a test strip on media, illuminating the media as the media on which the test strip is printed travels over the rotating member, generating electrical signals corresponding to light reflected by the media as the media on which the test strip is printed travels over the rotating member, converting the electrical signals to image data of the media on which the test strip is printed, modifying the image data of the media on which the test strip is printed with the image data of the blank media, and storing the modified image data in memory.

摘要： A method for processing input document data uses a drop mass history for ink jets in a print head to adjust other document data processing. The method includes ejecting ink in a plurality of patterns onto an image substrate from a plurality of ink jets, each drop in a pattern corresponding to one drop mass history in a plurality of drop mass histories, identifying a relationship between drop masses for the drops in an ejected pattern and a reflectance parameter for the ejected pattern, measuring a reflectance value for each pattern ejected onto the image substrate, and identifying a drop mass value for each drop mass history in the plurality of drop mass histories, each drop mass value being identified from the measured reflectance value for each pattern and the identified relationships between the drop masses and the reflectance parameter for each pattern.

摘要： In a printing system, a method is used for adjusting currents to LEDs in an LED printbar to achieve uniformity of the print. The line test pattern and halftone strips test pattern are printed. The test patterns are scanned. An LED line metric of each LED test pattern line and reflectance uniformity of each halftone test strip are measured. A line uniformity difference profile and a set of halftone strips uniformity difference profiles are concurrently calculated. A current value supplied to each LED associated with the test patterns is adjusted to simultaneously optimize the uniformity in the lines test pattern and the halftone strips test pattern.
