Review on 🖨️ Cool Toner Replacement Toner Cartridge for Canon 046H 046 MF733cdw Printer - Compatible with Canon ImageCLASS MF731cdw, MF733cdw, MF735cdw, LBP654cdw - Black Cyan Magenta Yellow, 4-Pack by Chad Siofele

Each cartridge was rejected by the printer as a counterfeit with the usual warning. Then the printer just stopped working. He neither copied nor printed with these cartridges. Replaced with original cartridges and everything worked again. I have previously used other brands of cartridges in this printer with no problems, but they were 100% defective and unusable. Absolute waste of money! DO NOT buy them. Other brands have worked but your printer will reject them and in our case will stop working until they are removed.
