Routine Maintenance

When Printing Becomes Faint or Colors Are Incorrect

When printing becomes faint or colors are incorrect, the print head nozzles on FINE Cartridges are probably clogged. Print the nozzle check pattern to confirm the condition of the nozzles and then perform Print Head Cleaning.

If print results are not satisfactory, performing Print Head Alignment may improve print quality.

Note

Before performing maintenance

•Make sure that a FINE Cartridge has not run out of ink. See "Getting the Ink Status Information" on page 46.

•Make sure that a FINE Cartridge is installed properly. See "Replacing FINE Cartridges" on page 47.

•Make sure that the orange protective tape is removed from the bottom of a FINE Cartridge.

•If the error message is displayed on the LCD, see "An Error Message Is Displayed on the LCD" on page 57.

•Increase the Print Quality setting in the printer driver settings. See "Print Results Not Satisfactory" on page 61.
