Question about Canon PIXMA MP780 All-In-One InkJet Printer
I have dep cleaned many times but the red ink will not print. I have replaced the ink in case it was a problem with that particual ink cartridge but same problem. Should I buy a cleaning kit? This is a replacement machine for the one I had under warranty and only came with a 90 day warranty (Staples voided the 1st warranty when they replaced the machine- bogus)
TAKE THE INK WELL OUT AND BOIL IT IN ALCOHOL (rubbing alcohol)
replace it and run a few deep cleaning
that should works fine
this printer ink well clogs and stadders quite often i had to boil man almost once ever cpl months
PLEASE NOTE THE ABOVE METHOD IS NOT CONVENTINAL BUT IT WORKS
other than that you can replace your ink well

Did you use third party carts?
If yes, buy original brother ink carts and do the cleaning cycle again. If you are lucky the printhead isnt clogged due to the third party ink which has not the additives and glycerin needed for the printhead to run without probs.
In case the head is clogged there is nothing more what you can do. Sorry! A replacement might costs more than a new mfc 440cn!
