I purchased a brother printer HL-L2350DW and when the cartridge ran out, I purchased a generic one from eBay. It worked well for a year. I may have done about 100-150 prints after replacing the cartridge, now it is showing No Toner error. It says Open the Front Cover and install Toner Cartridge.
I have tried to remove and re install cartridge, but the error doesn't go away.
Does anyone know to fix this error?
Guessing you updated your firmware?
No fix i've ever found apart from buying new cartridges that have updated chips. I stopped updating to get around this.
