•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.

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.
