How to Replace an Empty Ink Cartridge in the HP Deskjet 3720 All-in-One series Printer – an Illustrated Tutorial in 11 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 almost 3 times as many pages as a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.

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

To check the ink levels from the printer control panel
The ink level icons on the printer display show an estimate of ink remaining in the cartridges. The left ink icon shows the estimated ink level of the tri-color cartridge, and the right icon shows the estimated ink level of the black cartridge.

To check the ink levels from the HP printer software (Windows)
Open the HP printer software.
– In the printer software, click the Estimated Levels tab.

Use the single-cartridge mode to operate the HP All-in-One with only one print cartridge. The single-cartridge mode is initiated when a print cartridge is removed from the print cartridge carriage.

How to Replace an Empty Ink Cartridge in the HP Deskjet F4180 All-in-One series Printer – an Illustrated Tutorial in 12 Steps

Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled.

You can check the ink levels by using the HP Photosmart Software:
– In the HP Solution Center, click Settings, point to Print Settings, and then click Printer Toolbox. You can also open the Printer Toolbox from the Print Properties dialog box.
– Click the Estimated Ink Level tab.
The estimated ink levels for the print cartridges appear.


The Check Print Cartridge lights on the Control panel also inform you of the ink-status. The lights indicate the need to reinsert the specified print cartridge, replace the print cartridge, or close the print cartridge door. The Color light appears next to the three color drop icons and indicates that the problem is with the tri-color print cartridge. The Black/Photo light appears next to the single black drop icon and indicates that the problem is with the black or photo print cartridge.

Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable. You’ll usually install both the black and tri-color cartridges in the Deskjet, but you can use the ink-backup mode to operate the HP Deskjet with only one print cartridge. The ink-backup mode is initiated when a print cartridge is removed from the print cartridge carriage. This printing mode lets you print with a single print cartridge, but it slows the product and affects the quality of printouts.
