Cleaning the ink cartridge print head If the print head of the ink cartridge is dirty or the ink cartridge has not been used for a long period of time, it may not print properly. To clean the print head using the scanner, press the corresponding Custom Function button (F1 or F2) on the control panel. NOTE: You must assign the Clean Print Head function to one of the Custom Function buttons (F1 or F2) using the Ngenuity Operator Utility to be able to clean the print head using the scanner. See the section entitled, "Settings button: Custom functions" in Chapter 4. 1. In the NOU, go to the Settings screen, select Clean Print Head for either F1 or F2 key assignment, and save to the scanner. 2. On the scanner, make sure print head(s) are positioned properly to print at a desired print location. 3. Load one or more sheets of blank scrap paper that are wide enough to pass under the current print head locations, and are at least 5 inches long. 4. Lower the skimmer and to allow the paper to load. 5. Press either the F1 or F2 (as assigned) key. A single sheet will be fed and the print head cleaning pattern (a solid black stripe firing all print head pins) will be printed on the page by each imprinter that is installed. 6. Take the sheet from the exit tray and examine the printing. There should be a relatively solid black stripe approximately 1.5 inches long, with no voids or stripes. Voids or blank stripes indicate one or more clogged ink jet nozzles. 7. Press either the F1 or F2 (as assigned) key to feed additional pages until the printed black stripe is uniform and solid. This may take several sheets. 8. If, after 6 to8 sheets, you cannot achieve a solid black stripe then the print head should be removed from the imprinter and cleaned manually. See the next section, "Additional print head cleaning" for a more in-depth cleaning procedure. 9. Restore any previously set F key function via the NOU (if necessary). B-8 A-61662 October 2011
