printer cartridges

[gesnow]

My HP 4520 printer says after weeks of use, " the indicated cartridges are not intended for use in this printer". They are generic but I have used several before and this one for several weeks before this message appeared.

Hi @gesnow,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your HP ENVY 4520 printer shows a message about cartridges not being intended for use in the printer, it usually means that the printer has detected a compatibility issue with the cartridges. 

Here are some steps you can take to troubleshoot and potentially resolve the issue:

• Check Cartridge Compatibility: Ensure the cartridges you are using are compatible with the HP ENVY 4520. Even if they have worked before, there might have been a change in the cartridge's firmware or design that the printer is now recognizing as incompatible.
• Clean Contacts: Remove the cartridges and gently clean the contacts on both the cartridges and inside the printer using a lint-free cloth. This can sometimes resolve communication issues between the printer and the cartridges.
• Reset the Printer: Turn off the printer, unplug it from the power source, wait for about 60 seconds, and then plug it back in and turn it on. This can sometimes reset the printer's recognition of the cartridges.
• Update Printer Firmware: Check if there is a firmware update available for your printer. Updating the firmware can resolve compatibility issues with cartridges. Update the firmware on an HP printer
• Try Genuine Cartridges: If possible, try using genuine HP cartridges to see if the issue persists. This can help determine if the problem is with the generic cartridges or something else.
