Review on 2-Pack Compatible Toner Cartridge Replacement for Canon FAXPHONE L90 L120 imageCLASS D420 D480 Printer - GREENCYCLE C104 CRG 104 CRG104 FX9 FX10 Black by Tom Tofte

When installed in a Canon ImageClass MF4270 without printing graphics, this toner only lasted 1,351 pages. I think 98% of my print was within 5% coverage. that's about 700 pages less than the claimed 2,000 pages. Some printouts show smudges and sometimes traces of toner even after cleaning the fuser roller. However, for the price I could get them again as they are about $60 cheaper than the OEM cartridge.
