Using print cartridges

Everyday printing

Use the black and tri-color print cartridges for everyday print jobs.

For more vibrant colors when printing color photographs or other special documents, remove the black print cartridge and use a photo print cartridge in combination with the tri-color print cartridge.

For outstanding black and white photographs, remove the black print cartridge and use a gray photo print cartridge in combination with the tri-color print cartridge.

Replacing print cartridges

When buying print cartridges, look for the print cartridge selection number. You can find the selection number in three places:

•Selection number label: Look at the label on the print cartridge that you are replacing.

1.Selection number label

•Printer documentation: For a list of print cartridge selection numbers, see the reference guide that came with the printer.

•Print Cartridge Ordering Information dialog box: For a list of print cartridge selection numbers, open the printer Toolbox, click the Estimated Ink Level tab, and then click the Print Cartridge Ordering Information button.

If a print cartridge runs out of ink, the printer can operate in the ink-backup mode.
