Hi, I have a MFC-420CN printer which will not print in color. It prints black ink fine. A couple of the cartridges were near empty so I replaced all 3 color cartidges & still no luck. I even uninstalled & reinstalled the software. I went through the ink/test print & got the same thing. There are no error codes or problems, it just won't print any of the colors.
Have you check on your printer's color preference? It may only be a simple problem with your gray scale.Change the color preference on your printer icon's menu. You can also clean up your electronic connectors that comes in contact with the cartridges with a cotton dipped in alcohol.

Re: Won't print Color
this is a common prob of the brother printer.
It has nothing to do with the software and depends on the cartridges being used (are they thirdparty ones?) and in some cases air bubbles within the capillarysystem, or a defective valve within the printhead.
I guess before you have changed the carts everything was working quite normal. So, this in mind, try the following procedure:
Check cartridges if positioned well. Press them into position again, so that there is a good, open contact for ink to run into the capillaries!
Power on printer. Press menu then start mono (b/w) then 4x arrow-up-button. Machine will be in maintainance mode and beeps. Press 7 then 6. Machine displays Cleaning_all. Press 3. Power_p all will be displayed. Press start mono (b/w). Machine starts a power cleaning cycle. Wait until machine displays maintanance again. Press 0 (zero) then 9. Machine starts printing ink/test printsheet. If it is OK press 9 then 9 to quit the maintanance mode. If it is not OK press 7, 6 then 4 (init_all), then start mono (b/w). Machine will initialize the cartridges and clean the head. When finished press 0 , 9 again for test printing.
If you dont see any success after both procedures, your printhead may be clogged or dryed out.

By design, Brother printers stop all printing when one of the cartridges is empty. This is done to avoid cleaning cycles sucking air into the system, which could possibly damage the printhead.
Even if you print in black only by changing the print
settings to "Mono" or "Grayscale" to avoid printing in color, cleaning cycles would still **** air from the
empty color cartridge because they are programmed to clean ALL the ink
nozzles. The only way to continue printing is to replace the empty ink
After replacing the empty color cartridge, you could print in "Mono" or "Grayscale" to make better use of just the black ink.
The print head is clogged.Try powerful cleaning: Press menu, then start black copy, then four times arrow-up quickly after another.Machine will be in maintenance mode (all lights will flash). Press 7-6-4 and OK (or start-black-copy). When finished press 7-6-3 then start black copy, printer will do a power purge. Leave maintenance mode by pressing 9-9. If this not help better think about new printer, because cost of repairing this one is profitable.
The color cartridges print text that appears black by mixing the three primary colors (cyan, magenta, and yellow) to make composite black. To achieve a realistic black, large quantities of colored ink are used. Because black cartridges use much less ink to create a similar shade of black, they print more pages in black than the color cartridge.
If the color cartridges on the printer are next to empty, you will not be able to get perfect prints at all.
Please have the cartridges replaced to do the printing jobs again.
actually, its not. the reason is, there is a small resovoire (sp?) in the ink cartridges. if you continue to print, the nozzles will clog up, and can cause all the nozzles not to work. even when you do just black, the printer has to clean at times all the nozzles and if your nozzles are empty, air will go into the deep and dry up the excess ink.
if you are going to do primarily black prints, you should get a black and white laser for those uses only.
brother won't print od do anything is one of the 4 inks are empty so first of all you have to replace whatever is empty, when you remove it it will ask you if you changed it and if it is a new one you will press 1 twice per cartridge, if you put compatible ink in you will clog the ink head up and then be stuffed
unplug maqchine from power. take all carts out. wait 5 minutes. connect machine to power. insert carts as demanded. give the right answer if machine asks if the carts are changed. machine will do some cleaning.
do you use generic ink? in that case you might have clogged the printhead with wrong ink. The ph cant be cleaned anymore.
nevertheless try this (carts should be nearly full!): press menue then start mono (blue copy) then fourtimes arrow up. machine will be in maintenance mode. press 7 then 6 then 4. Machine will display init_all. press start mono. machine will refill tubes and ph with fresh ink and do some cleaning. after that press 7 then 6 then 3 and start mono. machine will do a powerpurge. press zero then 9 to do a quality test print. If it cant do the job leave maintenance by pressing 9 then 9. do the test print manually by pressing ink etc.
If you still do not see any colors the ph is clogged and cant be fixed anymore. It has to be replaced.
