imageCLASS MF642Cdw- Issue with Color Gradient/Streaks

Hi,

I just purchased this imageCLASS MF642Cdw printer (used) and replaced the cartridges with authentic Canon cartridges. I have yellow streaks in the documents I've tried to print. When trying to correct these issues using your suggested steps (adjust gradiation, cleaning ITB, etc.), I noticed yellow had a gradient that wasn't filled out like the other colors (see pictures below). 

I've tried shaking the cartridge but nothing improved. This cartridge is 100% full. Do you have any suggestions to fix this issue?

Greetings ,

For clarification, your printer model is actually a MF642 CDW.  I know the 6 kind of looks like a b but it is a 6.  

I think you've done all of the recommended steps you could possibly do. Bought new toner. Adjusted the gradation. Cleaned the ITB.  There is also a fixing assembly but I'm not sure it will help.  

@James_C corrected the title.  😊

Unfortunately none of those solutions helped 😕
