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 H ink light comes on or flashes, you cannot clean the print head. In this case, replace the appropriate ink cartridge first (see page 18).
1.Make sure the printer is on and the H ink light is off.
2.Hold down the H ink button for at least 3 seconds until the P power light starts flashing, then release it. The printer runs a head cleaning cycle, which takes about one minute.
Caution:
Never turn off the R280 Series during a cleaning cycle or you may damage it.
3.When the P power light stops flashing, run a nozzle check (as described on page 15) 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 print quality has not improved after repeating this procedure about four times, turn the printer off and wait for at least six hours. Then run the nozzle check again and repeat the head cleaning if necessary.
If you do not use your printer often, it is a good idea to print a few pages at least once a month to maintain good print quality.
