Review on GPC Image - Canon 045 045H CRG-045H CRG-045 Toner Cartridge 🖨️ Replacement - Compatible with Color ImageCLASS MF634Cdw MF632Cdw LBP612Cdw MF632 MF634 - 4-Pack by Matt Charlton

My printer used a different brand of discontinued toner for several months before it started spoiling every page printed. Pink splashes, dark streaks, completely unusable. I thought the printer was a waste. I decided to take a chance and buy a new toner. It worked! These toners have better colors and print quality than my previous toner. The prints are even, crisp and beautiful. (Note I've only had them 2 days but they still work great.) Unboxing tip: you have to pull the tab on the side when opening, they don't mention that the tab is longer than the entire cartridge . and finally you have to pull very hard to solve it. Otherwise installation was a breeze.
