Cleaning the Print Head If print quality has declined and the nozzle check pattern indicates clogged nozzles, you can clean the print head. Note: Print head cleaning uses ink, so clean it only if necessary. If the red B ink light comes on or flashes, you cannot clean the print head. In this case, replace the appropriate ink cartridge first (see page 20). 1. Make sure the all-in-one is on and the B ink light is off. 2. Hold down the y Stop button for at least 3 seconds until the P On light starts flashing. The all-in-one runs a head cleaning cycle, which takes about one minute. Caution: Never turn off the CX4400 Series during head cleaning or you may damage it. 3. When the P On light stops flashing, run a nozzle check (as described on page 17) to verify that the print head is clean. 4. 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 all-in-one and wait at least six hours to let any dried ink soften. Then try printing again. If you do not use your all-in-one often, it is a good idea to print a few pages at least once a month to maintain good print quality. 18 Maintaining Your All-in-One
