Cleaning the Print Head If print quality has declined and the nozzle check pattern indicates clogged nozzles, you can clean the print head. Print head cleaning uses ink, so clean it only if necessary. Note: You cannot clean the print head if an ink cartridge is expended or low. You must replace the cartridge first (see page 33). 1. Load letter-size paper in the sheet feeder (see page 5). 2. Press Setup. 3. Press l or r to select Maintenance and press OK. 4. Press d to select Head Cleaning and press OK. 5. Press x Start. Cleaning lasts around 1 minute. When it's finished, you see a message on the display screen. Caution: Never turn off the CX8400 Series during head cleaning or you may damage it. 6. Press x Start to run a nozzle check (as described on page 30) to verify that the print head is clean. 7. If there are still gaps or lines, or the test patterns are faint, run another cleaning cycle and check the nozzles again. Note: If you don't see any improvement after cleaning the print head two times, turn off your CX8400 Series and wait at least six hours to let any dried ink soften. Then try printing again. If you do not use your CX8400 Series often, it is a good idea to print a few pages at least once a month to maintain good print quality. Cleaning the Print Head 31
