Troubleshooting
Printing is Blurred/Colors are Wrong
■ Ensure that the clear film is completely removed from around the ink tank.
■ Ensure that the ink tanks snap into place when you install them.
■ If a specific color does not print, check whether the corresponding ink tank is
empty. Replace if necessary.
■ Print the nozzle check pattern to ensure that ink is output correctly.
If the nozzle check pattern does not print correctly, clean the print head.
