HP C5540, C5550 Ink-backupmode, Advanced print cartridge maintenance

Ink-backup mode

Use the ink-backup mode to operate the HP All-in-One with only one print cartridge. The ink-backup mode is initiated when a print cartridge is removed from the print cartridge carriage. During ink-backup mode, the product can only print jobs from the computer. You cannot initiate a print job from the control panel (such as copying or printing from a memory card).

NOTE: When the HP All-in-One operates in ink-backup mode, a message is displayed on screen. If the message is displayed and two print cartridges are installed in the product, verify that the protective piece of plastic tape has been removed from each print cartridge. When plastic tape covers the print cartridge contacts, the product cannot detect that the print cartridge is installed.
