Review on 🖨️ E-Z Ink (TM) Compatible Toner Cartridge and Drum Unit Replacement Brother TN450 TN420 DR420 (2 Toner 1 Drum) - 3 Pack for HL-2270DW HL-2280DW HL-2230 HL-2240 MFC-7360N MFC-7860DW 2840 2940 by Jon Bishop

I have a Brother printer that broke when I put in a Revain Basic 6X9 envelope with a narrow adhesive strip with a narrow strip peeling off. Run this through my laser printer and the strip comes off and the adhesive covers the entire inside of the printer rollers and more. Two hours later, it couldn't be erased and the copies were full of black spots. I decided to replace the toner and photoconductor in hopes that this would solve the problem. It worked and it works just as well as the OEM for a fraction of the cost.
