Managing Printer Keys​

Introduction​

Hello, I provide printer repair services, and I have purchased a lot of keys for the Epson C5290 printer. However, my printer recently updated its firmware and is no longer recognizing the ink cartridge. I am not sure which key my printer is currently using because I have about 100 keys. How can I check which key my printer is using? Do I need to purchase additional keys to recharge this printer? Thank you.

Key Management Tips​

1. Save printer serial numbers for all keys. This way, you will know which key corresponds to each serial number.

Lost Key Solution​

If you have forgotten which key is being used by your printer, you can try checking each key one by one to determine the correct one.
