Wont recognize new print cartridges as new, thinks old ones are new ones and visa versa

[BPoehler]

I replaced my depleted cartridges. They wouldn't show that I replaced them. I turned the printer off, unplugged, then back on, replaced with new cartridges., and now my printer thinks the new ones are the depleted ones and the old ones are the new ones. So if the new ones are in, it says they are depleted...if the old ones are in, it says thy are full.

Hi @BPoehler ,

Welcome to The HP Support Community.  

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

I understand your HP Officejet Pro 8600 is having trouble recognizing the new cartridges properly. Here are a few steps you can try to resolve this issue:

• Clean the Cartridge Contacts: Turn off the printer and open the cartridge access door. Remove the cartridges and clean the electrical contacts on both the cartridges and the printer using a lint-free cloth lightly dampened with distilled water. Make sure they are dry before reinserting them.
• Reset the Printer: Sometimes, a simple reset can resolve such issues. Turn off the printer, unplug it from the power source, and wait for a couple of minutes. Then plug it back in and turn it on.
• Update Firmware and Drivers: Ensure that your printer has the latest firmware and drivers installed. You can usually find these on the HP website. Sometimes, outdated firmware can cause cartridge recognition problems.  Update the firmware on an HP printer
• Manually Reset the Printer: Some HP printers have a procedure to reset the printer manually. This often involves holding down specific buttons while powering on the printer. Check your printer's manual or the HP website for instructions specific to your model.
• Try Different Cartridges: If you have access to another set of cartridges, try installing those to see if the issue persists. This can help determine whether the problem lies with the cartridges or the printer itself.
