Review on 🖨️ E-Z Ink (TM) Compatible Toner Cartridge Replacement for Brother TN350 TN-350 - High-Quality 2-Pack Black Cartridge for Intellifax 2820, 2920, HL-2070N, HL-2040, DCP-7020, MFC-7820n by David Sokolov

Each cartridge in this two-cartridge pack produced unusable "ghosting" or "bleed-through" images on the output pages. I think this is because the sensor rollers in the cartridge are not fully desensitized as they roll across the paper and transfer the toner to the sheet. Either that, or they don't "wipe off" excess toner like they do in the queue. In either case, the cartridges produce copies that are clearly unprofessional in appearance and of no commercial use. I recommend buying another brand with more quality control.
