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.

For information about installing a print cartridge, see the print cartridge installation page.

3.5 Ink-backup mode

In the ink-backup mode, the printer operates by using only one print cartridge. The ink-backup mode is initiated when a print cartridge is removed from the print cartridge cradle.

For instructions about removing a print cartridge, see the print cartridge installation page.

Ink-backup mode output

Printing in ink-backup mode slows the printer and affects the quality of printouts.
