I have a HP Officejet Pro 8600 plus. It will not accept new cartridges. Error message keeps coming up saying they are incompatible. How do I get them to work. I've updated my HP download on computer, but still not working. Tried unplugging it and reloading, and nothing is working! Help!!

@Sue-pro86_, Welcome to the HP Support Community!
Try inserting the old ink cartridges and check if the error persists.
Check if you are using a compatible HP ink cartridge
Also, perform step 2 to step 5 mentioned in this document.
Let me know how this goes.
