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.
When the ink level for an ink cartridge is low, a message appears on the display. You can also check the ink levels by using the printer Toolbox (Windows) or the HP Utility (Mac OS X). Click the Estimated Ink Levels tab to view the inklevel information, and then scroll to display the Cartridge Details button. Click the Cartridge Details button to view information about replacement 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. 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.
For your US, European and UK HP Officejet j4550 All-in-One Printer you need an HP 901 Black Original Ink Cartridge (CC653AN) and an HP 901 Tri-color Original Ink Cartridge or an HP 901XL CC654 Black High Yield Ink Cartridge. There are also Combo Packs (2 cartridges in one pack) available, like the HP 901XL Black and 901 Color Inkjet Cartridges.
Try Amazon's ink selector tool to find compatible ink cartridges for your printer.
Replace the ink cartridges
1. Before you replace the cartridges load plain white Letter or A4-sized paper in the input tray.
Remove the old cartridge
4. Lightly press down on one of the old cartridges to release it, and then pull the cartridge toward you out of its slot, and then set it aside for recycling. Remove the cartridge from the slot on the left to replace the tri-color cartridge. Remove the cartridge from the slot on the right to replace the black cartridge.
7. Slide the cartridge forward into the empty slot. Slide the new ink cartridge at a slight upward angle into the empty slot, and then gently push the ink cartridge until it snaps into place.
If you are installing the tri-color ink cartridge, slide it into the left slot. If you are installing a black ink cartridge, slide it into the right slot.
8. Repeat these steps to install the other ink cartridge, if necessary.
9. Close the front access door.
Align the cartridges
The HP All-in-One prompts you to align cartridges every time you install or replace an ink cartridge. You can also align the ink cartridges at any time from the device control panel or by using the software you installed with the device. Aligning the ink cartridges ensures high-quality output. If you remove and reinstall the same ink cartridge, the device will not prompt you to align the ink cartridges. It remembers the alignment values for that ink cartridge, so you do not need to realign the ink cartridges.
12. Close the scanner lid and then press OK.
13. Recycle or discard the ink cartridge alignment sheet.
