Deskjet F340 cannot recognize brand new HP 21 ink cartridge

HP Recommended
Microsoft Windows 10 (64-bit)

Hi, I have the exact same problem as described in this question: Defective brand new HP 21 ink cartridge? - HP Support Community - 7921339. My Deskjet F340 is using HP 21 ink cartridge, and I put a brand new cartridge into my printer, and my printer cannot recognize it. I took it out and inserted my old empty cartridge and my printer instantly recognized it. I took a close look into the copper colored contact, and it looked different from the previous one. Is there any changes made to the new cartridge, and is now no longer compatible with older printers? Thank you.
