Jeostarky Compatible Canon 067H 067 Toner Cartridge Set Replacement for Canon 067H Compatible for Color ImageClass MF656Cdw LBP632Cdw MF654Cdw MF653Cdw LBP633Cdw MF650C LBP630C Printer (4 Pack)

Started out printing fine, by the time the cartridges reached about 75% full, there was red scatter on every page and it got worse and worse. I did all the cleaning routines the printer allows (Canon MF650cdw) and it got somewhat better. The magenta cartridge does not seem to keep the toner contained. There is red toner collecting in various places on the outside of the cartridge. The cartridge's roller has speckles on it, the IBT belt has red speckles all over it. What a mess. If I try to print a solid red shape, I get a streaky gradation from red to yellow orange. The other carts are so-so, Black and Cyan are streaky but not leaking. It only takes one bad cart to ruin all your prints. I think these are poor quality all around, toner, construction, design. I have had bad experiences with other cheap brands also. I'm ready to bite the bullet and spring for OEM. I hope I haven't ruined the printer.

Sure these work instead of paying hundreds of $$$ from the Canon brand; however, I regularly receive an error on one or two individuals colors stating the toner is low, the first time was several minutes after installing all of them out of the box. Printing continues and looks excellent so the intermittent and periodic issues is either the cartridge chip technology itself or incompatibility of the electronics between Canon and an aftermarket product. As long as they print I will be happy but the bogus “low toner warning” is annoying.

Constant color issues, extra lines.

The black cartridge leaked toner. It was a pain to get the printer cleaned back up. I ended up having to buy an OEM black cartridge as a replacement. Black was what I needed when I ordered this pack so I haven’t used all of the cartridges. So far the one color cartridge I am using is okay.

Print quality is poor- because these aren’t genuine Canon products you can not adjust the printer or maintain the quality. They print light to dark in gradation and sometimes they print fine. Either way- not okay to waste expensive labels and get a weird color contrast.
