I have brother mfc 420CN printer and it is stating that the mgent is near empty. What does that mean

Printer has detected low level of this color ink. The warning is telling you the ink is about to run out completely very soon. It should still be printing ok until it does run out. Then the message will read "Mgnta tank empty". All printing will then stop. Best to get a new set of cartridges ready as they usually all run out about the same time.

Try unplugging the printer, waiting a few minutes and replugging it back in.

Hello,

The MFC-420CN is part of the BH3 series which brother did not develop drivers or software for compatible with Windows 7.

This does not mean it is not compatible though.
What this means is that you can only use the built in drivers with windows 7.

When you plug is with a USB cable, it should install automatically for printing and scanning.

If you are using a network, you can go through the add a printer in "Devices and printers" but wont be able to scan.

If WIndows does not give you the option to select the MFC-420CN, then you will need to complete a windows update to have the driver.

Thanks,

Pat

This is only a reminder! The cart will show "empty" when it is really empty. You can print on until the printer stopps because of empty cart (and prints on when it is replaced).
Take the new on out and put it in again. answer display question with "1" (Yes, cart changed). "Near empty" Message will disappear.

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.

Open the small cover that hides the scanner flat cable. It has to be reconnected to the main pcb.

If you have used third party carts before you can't repair this problem due to the fact that the filter inside the printhead is clogged with particles. There is no chance to clean the filter. Sorry. Do use only dye ink. Pigmented ink is the printhead killer for brother printers!
