Re: ink cartridges....

Somethings that have 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".

2. The cartridge holder in the printer has an "electronic eye" (light sensor) of some type for each cartridge.
Some users have found that putting either permanent marker/sharpie/black PVC tape either on the area of the ink cartridge that goes near the sensor or alternatively putting tape over the sensor itself allows printing to occur.
The problem with this method is that the printer will no longer recognise near-empty cartridges and so will not warn you to replace them and so the print head may be damaged. This is said to work on LC57 icartridges used with the following models: DCP-330C, DCP-350C, DCP-540CN, DCP-560CN, FAX-2480C, MFC-240C, MFC-440CN, MFC-465CN, MFC-665CW, MFC-685CW, MFC-885CW, MFC-3360C, MFC-5460CN, MFC-5860CN.

Re: ink cartridges....

Which cart arent recognized? The yellow one or the cyan(blue) one or both?

Unplug machine from power. Wait three minutes. In this time take all carts out and close cover. reconnect machine to power. Machine demands carts. Open cover. Reinsert carts. Make sure that the support clip of the cart.holder is secured above the cart cover.

If you still have probs with one cart. the led contact on the circuit board is defectiv. You need a new cart holder then, which can be ordered as a spare part from a service partner near your home (see brother homepage).

Brothers MFC885cw can't recognize new cartridge

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled (the absolute worst possible choice) or third party cartridges (2nd. Worst possible choice) that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

How to change an ink cartridge on the Brother MFC-240C

The Brother MFC-240C uses an individual cartridge for each color (black, yellow, cyan, and magenta). When one of the colors is out of ink, the printer will tell you to replace the ink cartridge. To replace a cartridge, follow the steps below.

All four cartridges are located on the right front side of the printer, behind a cover. Pull the cover forward from the side, where there is a slight cutout for you to grab. When the cover falls forward, you'll see the ink cartridge holders.

For whichever ink cartridge you are replacing, push down on the purple handle for that color. The ink cartridge holder will open and fall forward, revealing the ink cartridge itself. Push down on the cartridge holder and the cartridge should pop toward you a little bit. Grasp the cartridge and remove it.

Open the new cartridge and remove it from its wrapper. Discard the yellow cover, unless you plan to use it for the old cartridge.

Insert the new cartridge into the correct slot (from left to right: black, yellow, cyan, magenta) so that the word "brother" is right-side up and located toward the top of the cartridge. Once it is most of the way in, push the ink cartridge holder up by the purple handle until it snaps into place. Then close the ink cartridge cover.

If you were out of ink, the machine should recognize the new cartridge and perform its calibration. If it doesn't automatically recognize it, it will ask if you have changed one or more of the cartridges. Press "1" for Yes.

Once you have printed a test page with all four colors to verify that everything is working, either discard the old cartridge in the trash or save it to recycle. But don't get rid of it until you are sure the new cartridge is recognized and working.

I have an MFC-3240C which was showing "Ink Empty Yellow Replace Ink". No matter what I tried (including new brother yellow cartridge) the problem remained. I bought a second-hand MFC-620N. Hooked it up -...

You must be reset your ink cartridge by printer maintenance software.Or originally cartridge is damage.If you can not fix this problem.Please go to a service center in your area.

Changed yellow ink to new cartridge. Printer won't recognize.

I contacted the Brother site, the support function there. Pursuant to what I found there, I unplugged the printer for ten seconds and replugged. The message display then told me that cyan was empty, and that magenta was near empty.

I installed a new cartridge in place of the empty cyan, and that fixed it.

Oh brother

I don't think there is a reset procedure for resetting MFC 3240c cartridges.
Professional refill facilities use a code reset device on cartridges.
Users that want to refill their own cartridges often use a piece of cellotape or plastic bag to cover cartridge sensor. This can damage printers head if ink goes too low and printer keeps printing.
My suggestion: stay away from troubles and buy original cartridges.

Will not accept new yellow ink cartridge.

Do you use generic carts?
If yes try another cart (always best: original brother carts)
