Cleaning the Print Head
Using the Head Cleaning utility
Using the control panel buttons
If you find that the printed image is unexpectedly faint or dots in the printed image are missing, you may be able to solve these problems by cleaning the print head, which ensures that the nozzles are delivering ink properly.
You can clean the print head from your computer using the Head Cleaning utility in the printer software, or from the printer itself by using the printer's control panel buttons.
 |
Note:
|
 | -
Print head cleaning uses both color and black ink. To avoid wasting ink, clean the print head only if print quality declines; for example, if the printout is blurry or the color is incorrect or missing.
|
| -
Use the Nozzle Check utility first to confirm that the print head needs to be cleaned. This saves ink.
|
| -
When the
 error light is flashing or on, you cannot clean the print head. Replace the appropriate ink cartridge first.
|
| -
Do not start the Head Cleaning or Nozzle Check utility while printing is in progress; otherwise, your printout may be marred.

Print head needs to be cleaned

In the check pattern, if you find that any segments are missing from the test lines, you may need to repeat the head cleaning and print the nozzle check pattern again.
If print quality hasn't improved after repeating this procedure four or five times, turn the printer off and leave it alone overnight. Then do the head cleaning again.
If the print quality still has not improved, one or both of your ink cartridges may be old or damaged and may need to be replaced. To replace an ink cartridge before it is empty, see Replacing an Ink Cartridge.
If print quality remains a problem after replacing the ink cartridges, contact your dealer.
