Encountering a "Replace Unsupported Cartridge" error on your Lexmark MS321, MS421, MX321 or MX421 series printer can be a frustrating experience. This error typically indicates that the printer does not recognize the installed cartridge, which could be due to a variety of reasons such as a communication issue between the cartridge and the printer, or a fault in the cartridge itself.
According to Lexmark, the specific error Replace unsupported cartridge [32.40B] indicates that the installed toner cartridge "failed capacity class/model compatibility check". Simply put, the printer recognizes that the installed cartridge is not designed to work in it. There are three primary reasons you could be seeing this error:
- A toner cartridge was installed with a higher yield than the printer will accept.
- A toner cartridge was installed that is designed to work in a different series of printers.
- A toner cartridge was installed with a defective microchip.
All three scenarios above can happen regardless of using a genuine Lexmark cartridge or an aftermarket replacement. Your best option to resolve this error is to replace the toner cartridge and ensure its specifications lists your specific Lexmark printer model as compatible.
Here's an example series of Lexmark printers and the compatible yield levels:
| Standard Yield | High Yield | Extra High Yield | Ultra High Yield | |
| MS321 Series | Yes | Yes | No | No |
| MS421 Series | Yes | Yes | Yes | No |
| MS521 Series | Yes | Yes | Yes | Yes |
| MS621 Series | Yes | Yes | Yes | Yes |
