[Fault]
I have a Brother MFC 9420CN that is missing the Yellow and Magneta colours
down the left half only on the copy. The right half of the copy looks perfect.
The copy appears blue(cyan) down the left half of the page.
The Cyan colour is consistent and works fine.
Printing works perfect on black.
[Solution]
I have replaced the PCU belt the Transfer Drum etc.
I have put 4 new toner cartridges in the machine.
[On going]
After I put 4 new toner cartridges into the machine everthing worked fine for about 20 copies and the yellow and magenta slowly reverted back to the original half page copy fault.
Any ideas would be appreciated.
