What does 'Cartridge, imaging unit mismatch' mean on my Lexmark MS711 and how to fix it?
- JJoshua MartinezAug 30, 2025
If your Lexmark printer displays a 'Cartridge, imaging unit mismatch' error, check if both the toner cartridge and imaging unit are MICR (Magnetic Ink Character Recognition) or non-MICR supplies. Change either the toner cartridge or the imaging unit, so that both are either MICR or non-MICR.
