HP Photosmart C4435 All-in-One Printer - Manual (Page 80)

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 scanning an
original).
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.

Advanced print cartridge maintenance
