الفرآت تك 0 Report post Posted September 13 Hello, I'm a printer engineer working in a printer repair and setup shop. I use chip-free firmware and yours, but I'm having a problem. After installing the firmware for two months or more, I get an error message in the system, error code 308600. This problem has occurred with more than one printer, so I would appreciate your help in resolving it. Thank you. Share this post Link to post Share on other sites
