grzegorz 0 Report post Posted March 30, 2020 I have just bought code for disable cartridge firmware ,,,everything goes OK Please, remember, that fatal errors are not related to the waste overflow errors and they can not be reset by software. If you experience communication errors or do not see your printer, please, try the following: - Restart the printer and PC. Make sure that USB/Wi-Fi connection is of the good quality. Try to change USB cable and port if applicable. - Cancel all printer jobs and disable all applications and services that can communicate with the printer. Please ensure that you typed entire key correctly and that you have not input a PayPal transaction ID or similar by mistake. Start uploading firmware to the printer. BUT IT DOESNT WORK :-(((((((( could you help me ? my email - kosmit007@icloud.com i have been trying everything ....still low level on a few inks .....nothing has changed ....
