Question about Brother MFC 420CN All-In-One InkJet Printer
The color cartridges are low; one empty. I replaced the black, but
my printer won't work. I tried the black electrical tape on the nose
of the color cartridges hoping to fool the sensor but it didn't work.
Is there another quick fix I'm missing for this model. I just want
the black to work. Thanks for any help.
What type of machine do you run?!! MFC420 or mfc 5460?!!
Is it a machine with LC51 or LC41 carts?
In both way: Did you check the other carts? It could be that there is another one empty.
Did you stick the tape at the right place, too? The tape should be a bit larger than shown on the pic.
For the LC51 it it the same position.
Did you answer the printers question of changing the cart with YES?

or needs replacing. Be sure to follow the LCD
prompts to replace the ink cartridges in the
Even though the machine tells you that an ink
cartridge is empty, there will be a small
amount of ink left in the ink cartridge. It is
necessary to keep some ink in the ink
cartridge to prevent air from drying out and
damaging the print head assembly.

for example Black, the LCD shows

take out the ink cartridge for the color
shown on the LCD.
c Open the new ink cartridge bag for the
color shown on the LCD, and then take

when you open the bag, the cartridge will
not be damaged.

may ask you to verify that it was a brand
new one. (For example,
Did You Change Blck?) For each
new cartridge you installed, press 1
(Yes) to automatically reset the ink dot
counter for that color. If the ink cartridge
you installed is not a brand new one, be
