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).
