Review on TEINO Compatible Toner Cartridge for Canon 054 CRG-054 🖨️ - Perfect for imageCLASS MF644Cdw MF642Cdw LBP622Cdw MF640C (Black, 1-Pack) by Brent Webb

Maybe I just have a bad cartridge, I don't know. But I bought this one on June 12th, installed it a few weeks ago (early August) and probably printed less than 200-250 pages (on the high side I think to be honest). Take out the cartridge and shake it as half of the pages are faded. Now today when I print there is a 1 inch unprinted gap about 3 inches from the edge of the page. Gently shaking the cartridge from side to side worked again, but I don't think I had to do that. I don't think I will buy these again.
