Question about Brother MFC-640CW All-In-One InkJet Printer
The alignment has to be fixed by service personal. Theres no way you can fix it by yourself because special software and drivers needed which are only accessable for service dealers.
Run a power purge. Do use nearly full carts, because it consumes some ink!
Press menu then start black copy then fourtimes arrow-up (tel.index). press 7 then 6 then 3 then start black copy. Repeat power purge. Leave meaintenance by pressing 9 then 9. If there is still trouble with color the printhead needs replacement.
Error43: white flat cable of print head not connected correctly.
Check ph and circuit board if connected and placed well. If it is good and still problems left, the circuit boards (ph and/or main) are defective. Needs replacment then.
