[Fix] What to Do When HP Printer Not Recognizing the Ink Cartridge?

There are all kinds of error messages that an HP printer displays which are related to the ink cartridges, but one of the most common is the ‘No Cartridge Installed’ error message. There are some variations of this error message, like ‘Printer Cartridge Not Detected’, ‘HP cartridges locked’ etc. All these errors mean the same thing, that your HP printer is unable to recognize the ink cartridge which is installed in your printer. In this guide, we will do an in-depth research on this problem and tell you what to do when HP printer not recognizing the ink cartridge.

Why is HP Printer Not Recognizing the Ink Cartridge?

When you are installing a non-compatible ink cartridge in your HP printer, then it is most likely that your printer won’t be able to recognize it. However, when you encounter this problem with HP compatible or HP original ink cartridges, then it can be surprising. Actually, there are certain conditions which can cause this error in an HP printer, even if the ink cartridge you are trying to install is the right cartridge for that printer.

• Issues with Printer’s Internal Memory: The internal memory of your printer has information about its ink cartridges. However, if this internal memory is filled, then your HP printer will be unable to determine that the new ink cartridge has been installed as the internal memory will keep showing the details of the old cartridge. While in some cases, the HP printer will show the ‘No Cartridge Installed’ error because the internal memory is unable to update itself.
• Dirty contact points: HP printer transmits the printing signals electronically to the ink cartridge. Therefore, there are several metal contacts between the printer and the ink cartridge. If these contacts get dirty, then your HP printer will not be able to detect the newly installed ink cartridge.
• Protective Strip is still stick on the ink cartridge: Each ink cartridge has a protective strip to protect the metal contacts of the ink cartridge. You are supposed to remove this protective strip before installing the ink cartridge on a printer. However, if you haven’t removed this protective strip or some fragments of this strip still remain on the ink cartridge, then your HP printer will be unable to detect the new ink cartridge.
• HP Cartridge Protection is Activated: HP printers come with a feature to protect itself from low-grade ink cartridges so that you get the best quality prints from your printer, this feature is called the HP cartridge protection. If this feature is enabled in your printer, then it can detect compatible, refilled or remanufactured HP ink cartridges as faulty ink cartridges and show you errors, like ‘Printer Cartridge Not Detected’.
• Cartridge is Installed Improperly: The most common cause is when you install your new ink cartridge improperly. It might happen that you have installed the ink cartridge in the wrong slot, like the color cartridge in the slot of the Black cartridge or vice versa. Also, if the cartridge is loosely placed and not properly fixed in its slot, then you can experience HP printer not recognizing the ink cartridge problem.

As you can see, there can be several reasons behind this problem and so there are many solutions. We have shared all the solutions for the above causes in the next section.
