We do not recommend using a photo print cartridge for ink-backup mode. Printing in ink-backup mode slows the printer and affects the quality of printouts. The ink-backup mode is initiated when an ink cartridge is removed from the print cartridge cradle. Use the Reserve Mode (ink-backup mode) to operate the HP Photosmart 7150 Printer with only one ink cartridge. You do not have to replace the ink cartridges until the print quality is unacceptable.
When you receive a low-ink warning message, consider having a replacement ink cartridge available to avoid possible printing delays. Ink level warnings and indicators provide estimates for planning purposes only.
HP recommends that you use original HP ink cartridges. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. HP often designs its inkjet hardware to use country-specific consumables. Cartridges are not compatible between different brands, and often not within the same brand. Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled.
