Question about Brother MFC-425CN Multi-Function Center All-In-One InkJet Printer
I have been using this printer for about a year and it's really good but it true style come the time when it is important it has decided it does not want to print black. Have done several cleaning sessions on it and still not wanting to print any ideas would be great as cannot afford to get a new one.
Do you use generic ink? If yes it can be that the bk channel within the print head is clogged due to wrong ink consistence.
What you can try is this:
1. Make sure that the cart is placed well and the hook secures the cart.
2. press menu then start bk copy then fourtimes arrow-up. machine will be in maintenance mode. press 7 then 6 then 4 then start bk copy. machine will refresh ink in tubes and ph and run some special cleaning procedure. when finished press 7 then 6 then 3 then start bk copy. machine will run a power purge. leave maintenance mode afterwards by pressing 9 then 9. run a test print. if you still cant see bk the ph is clogged and cant be fixed anymore!
