Review on 🖨️ GPC Image Compatible Toner Cartridge Replacement for Canon 054H CRG 054 - Black, Cyan, Magenta, Yellow - Ideal for ImageClass LBP622Cdw, MF644Cdw, MF642Cdw, MF640C, LBP620 Toner Printers by John Brouillard

The office manager complained about streaks and requested more toner. I just ordered 2 sets of these a few months ago. Turns out she had already used up all the cartridges and the printer hadn't even printed 1000 pages since I bought her. Those LEAKS are everywhere and you can hear and feel that there is still LOTS of UNUSED toner in those BROKEN cartridges. I've always bought GPC and another brand for HP in the past because they were great aftermarket toners. I think they stink of canon. Now, even with Canon's OEM cartridges, the printer is still having trouble printing because those things DISCHARGE so much toner into the machine. Now I have to pay to have the printer fixed because I trusted the GPC and I also don't have a return window. I'm considering contacting Revain or my credit card for this shoddy, unacceptable product.
