How to Replace an Empty Ink Cartridge in the HP Deskjet 5940 series Printer – an Illustrated Tutorial in 9 Steps

Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. HP often designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. 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.

HP recommends that you use original HP ink cartridges. XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print at least double the pages of a regular cartridge. However, (original) HP XL cartridges for the HP Deskjet 5940 printer are NOT available. Basically HP 96 and HP 97 are XL versions of HP 98 and 95 cartridges.

Follow these instructions to view the estimated ink levels of the print cartridges that are installed in the printer:
– Open the HP Printer Utility.
– Select Supplies Status.

Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement ink cartridge available to avoid possible printing delays. You do not have to replace the ink cartridges until the print quality is unacceptable.

Use the ink-backup mode to operate the Deskjet 5940 with only one ink cartridge. The ink-backup mode is initiated when an ink cartridge is removed from the print cartridge cradle. Printing in ink-backup mode slows the printer and affects the quality of printouts. HP does not recommend using the photo print cartridge or the gray photo print cartridge for ink-backup mode.

Print cartridge combinations
Three print cartridges can be used with the printer. For everyday printing: Use a black cartridge along with a tri-color cartridge. For printing color photos: Use a photo cartridge along with a tri-color cartridge. Always install the tri-color print cartridge in the left side of the print cartridge cradle. Install the black OR photo print cartridge in the right side of the print cartridge cradle.

1. Black print cartridge
2. Tri-color print cartridge
3. Photo print cartridge
