Question about Brother MFC 420CN All-In-One InkJet Printer
All ink cartridges have been replaced. I have carefully replaced cartridges and am sure they are in correctly. Message on screen says lift cover and replace all colors...no ink black, etc.
Try this : press menu,2864,*.....to neter maintenance mode....after press 7,6,4 and black start key. This will purge the machine do it about 2-3 time to make shure. It can take from 3 -5 minutes each time you try it. If it don't work.....sorry but you will have to change your print head...... need other tips : firstname.lastname@example.org

Did you use original carts? In case your carts are third party ones, this is a common problem due to diffrent construction of the carts. Disconnect mfc from power (unplug!). Open cover, take carts out. Wait two minutes. Reconnect (plug in) mfc to power. mfc demands carts. Place the carts right back. mfc should start cleaning. In case you are asked if carts are replaced push yes (1). Set date and hour again (and faxnr. etc)... http://welcome.solutions.brother.com/bsc/public/us/us/en/faq/faq_list.html?reg=us&c=us&lang=en&prod=mfc420cn_us&Cat=16
