Why does my HP printer keep saying cartridge problem? Please check and wipe the cartridge contacts. The common cause of the cartridge problem message is the gold contacts found on an electronic chip on the body of the HP cartridge being cloaked with dirt or ink or even because of physical damage.
To override HP ink cartridge error, remove and reinstall the indicated cartridge 2-3 times until it firmly seats in the slot. Then turn off the printer and remove all cartridges. Gently, with a dry lint-free cloth, wipe the contacts on the cartridge and carriage to remove any dirt or residue.
“One or more cartridges appear to be damaged. Remove them and replace with new cartridges.” Most commonly “Cartridge Problem” means that your HP printer simply cannot recognise the colour or black ink cartridges.
Clean the Cartridge Contacts: one of the most common reasons you might get a cartridge problem error when your cartridges are new and full is the contacts on the cartridge might be dirty or otherwise obscured from making good contact with the electronics in the printer head carriage.
Open Settings -> Devices -> Printers and Scanners (or run a quick access URI command: ms-settings:printers ); Select a printer you want to remove and click Remove Device; Confirm the printer removal.
From the control panel go to : setup menu>printer maintenance and then select either cold reset or factory reset. cold reset: Resets printer to out-of-box condition, startup questions like self or IT managed will appear are initial prompts again.

Error message reads remove and check right cartridge
ANSWER : You can try cleaning the contacts on the back of the cartridge and the ones that they contact in the printer. Other than that, you have to replace the cartridge. I once had one that did the same thing. I swapped the cartridge with another printer of the same model and both printers worked fine. I swapped them back and the original printer got the same error. The other printer had no problem with either cartridge. I swapped them back and left them that way.
