Until 2 weeks ago the printer was able to change toners without issue. Since then, only the MICR toner is recognized and accepted in my M404.  I've tried validating the standard toner using the QR code, but nothing has helped.  Please provide a solution as the accounting team does not like using MICR for non-check printing due to cost.  

 

Also, we are unable to update the firmware:
