After firmware update it show's unsupported cartige [32.49]

After updating Lexmark M321dn with firmware from official site it shows error "Replace unsupported cartige [32.49] but inside is original Lexmark toner. Will it new toner fix that error?

If the toner is old, firmware updates can cause this.

I have seen this alert show up after a firmware update and the toner cartridge in the machine had the old Lexmark logo on it. Install a toner with the new Lexmark logo and it works.
