Review on 🖨️ MYCARTRIDGE Black Toner Cartridge Replacement for Canon 054H CRG-054H 054 | Compatible with Image Class MF644Cdw MF642Cdw MF640C LBP622Cdw LBP620 | 1-Pack by Alan Miller

I used this in a Canon LBP622Cdw. As others have said, the print quality is indistinguishable from Canon toner. What worries me is that I've printed at least 100 pages since installing this cartridge and the printer's 'gas gauge' says it's still 100% full. I wonder if this represents a chip bug. I had one more concern. After installation, it took the printer at least two minutes to 'decide' that it would work with the new cartridge. But it eventually came to life and has been in excellent printing ever since.
