MF644Cdw yellow streaks

[FrankCurrah]

Color imageCLASS MF644Cdw keeps giving me yellow streaks only on print side.  I've circled them in red on the image below....

I've tried:

1) removing and reinstall the toner cartridges;

2) "clean fixing assembly"; and

3) "clean ITB"

4) "reduce drum steak";

Hi FrankCurrah.

With consideration to the steps you've taken and the symptoms, this may be a problem with the yellow toner cartridge's drum.  If the yellow toner is still within the thirty (30) day post-purchase warranty period, contact us using the numbers and information at http://Canon.us/ContactLI 

If the toner is no longer under warranty, try replacing it with a fresh yellow toner cartridge (Toner 054 standard or High Capacity).

There is no accept solution button?  We're going to use out the yellow toner then replace...

I have the MF632 and I am having the same issue now. How did you fix it .

After replacing the yellow cartridge and cleaning up, the issue went away.
