Brother MFC-420CN Multifunction Printer Problem

I replaced all of the cartridges with new Brother original cartridges. The printer keeps telling me to install cyan. I have installed it many times, but still says "Install cyan". How do I get out of this problem? I answered the questions in the LCD, but still says "Install cyan".

Re: Brother MFC-420CN Multifunction Printer Problem

I had the same problem. Brother has a firmware update that is supposed to solve it. I tried it, &, so far, it appears to have done the trick. However, I'm experiencing an intermittant printing problem (i.e. it doesn't) & don't know if there's a relationship between the 2. The printer fails to print (although the Office s/w send the data, & it shows up in the print queue) . This happens always from Office 07, but if I reboot everything & print a test page it works, also prints from MS Works--but not if I have launched Office.

Just replaced ink cartridges on my Brother MFC

Hi there you can refill Brother cartidges, like other printers it will not have it sorry.

This is the only way you can trick it.

There are only a few steps you need to do to reset a Brother printer ink cartridge and once you do it, you will be up and printing in no time. There are actually two things that a Brother printer uses to detect ink and you can manipulate one or the other.
Things You'll Need: · Black electrical tape, masking tape or duct tape
1. Step 1
Identify the printer If your printer uses memory, you can tell which printer you have by looking at where the cartridge goes in, if you see two "eyes" and a part of the cartridge goes in between them, follow Step 3. Otherwise, continue with Step 2.
2. Step 2
Clear the memory by taking the cartridge out and unplugging the unit for 30 seconds. Then, plug it back in and put back in the cartridge. You may need to do this five times, as the memory holds the last five cartridges.
3. Step 3
If the Brother printer has "eyes" where the cartridge goes, you will need to block in between them with a piece of tape so that it thinks the cartridge is always full. Simply put a piece of tape on the piece of the cartridge that goes in between the eyes to block the path of the infrared beam

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Black ink on my Brother MFC-420CN is faint and streaky

You said you replaced the cartridges. Were they Genuine Brothers' Cartridges?

My Brother MFC-240C, does not like Generic Printer Cartridges. That sounds like your problem. Also I had with Brother's was problem with Color. Color that should be Yellow, will turn out Green, or Blue Green, etc. The Generic Cartridges, also printed lines thru the words. That's what the Companies do., so they can keep selling the ink cartridges.

Some Printers, are able to use Generic, but you have to fill them up yourself and I heard, quite MESSY, or Take them to have them filled.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for the PRINTERS.

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)

When inserting a new cartridge, you may receive a prompt

"The installed ink cartridge differs from the original ink cartridge for the printer. Your printouts may be different from those printed using original ink cartridges. Do you want to continue using the currently installed ink cartridge?"

If you click Yes, printing will continue. If you select No, you will be prompted to change the cartridge. Manufacturer prompts may vary.

How to refill Brother MFC 420CN ink cartridge?

I wouldn't recommend refilling cartridges anymore. Nowadays printers come with a sensor which tell it which cartridges were used and refilled. Also do not use generic cartridges. Always buy genuine cartridges. Will save you a lot of headache in the long run...Trust me.

Red Menace

Try unplugging the printer for about ten to fifteen seconds; then replug.

This may clear the printer's memory about the low magenta. I had a similar thing with yellow, and when I replugged it stopped complaining about the yellow and told me that my cyan was out, and magenta low. I replaced the cyan, and voila! I can print!

MFC-420cn printer says install cartridge. But there is a new one just installed.

by useing original brother carts instead of poor designed generic ones.

Or by answering the lcd-display question if you have changed the cart.

or by making sure that the plastic nose secures the cart which was placed well into the holder.

If that doesnt work, the circuit board might be defective.

Mfc brother printer

Something that has worked for some Brother owners to get cartridges recognised.

1. With your MFC powered up, open it up and remove the cartridge you are having a problem with, then close the MFC, leaving it powered up. It should report that there is no cartridge in the machine.

Still with the MFC powered up, open it up and reinsert the ink cartridge, then close the MFC. It should either ask if you have replaced a cartridge or go into its cleaning mode.

Answer "yes" to "have you replaced cartridge?" and it should either "print" or "clean" and then "print".
