Is there a way to over ride a replace toner message? It stopped printing black and white with an empty yellow toner.

No I have not found a way to do that. I just had the same problem and luckily had a new cartridge handy. I get the best service and prices from inkjetsuperstore.com. Also fast delivery. I always order 2 of what I need. So when I put in the second one, I order more so I won't be in a bind. Older printers would let you take out the cartridge and shake it and put it back in but not this one. This printer is not the easiest to operate. It has a mind of its own.

There are aftermarket toner cartridge reset chips available. You can temporarily swap the chip in the yellow toner cartridge while you are waiting for a replacement yellow cartridge to arrive. However, this assumes you have a small ssupply of reset chips on hand. Chicken, egg.

If you are specifying "grayscale" or "black & White" in the print command, you have right to expect the printer to print it so. If you leave it to s/w to decide whether you need yellow, it won't.

I would contact the seller and return it. I am still doing really well with mine. Often, when toners like this are produced in high volume, their are duds occasionally. I am certain the seller would be happy to remedy the issue with you. I have not had any issues like this yet, In fact, it worked right out of the box. Also always double check the cartridge number and model number. I hope this helps. If you communicate with therm they should fix this... Take care.

Call Technical support. They have been absolutely wonderful with me on every occasion! and, the only other thing I would suggest is with the new cartridge of black in place, disconnect your printer from the electrical outlet and shut down your computer. Then, restart your computer and restart your printer to see if that makes a difference. Otherwise, call KM. They are wonderful! And, these printers are wonderful although a bit "sensitive."

My experience has been that it just stops dead in the middle of a print job if ANY cartridge is "empty". This is very annoying, especially if (as is often with me) I'm only printing B/W.

Take the toner out and re-install the old toner back and see if you still hear the loud noise. if it prints with out the loud noise, try put back the new one in and see if it works. maybe it wasn't seated properly.

usually the machine will give you a message that you need a new drum, did you use the OEM toner cartridge ? this may casuse a problem

When ever I see white blotches, I believe the toner is running out. However, to be sure, you should take the cartridge and shake it up and down, sideways, etc. This will distribute the toner even again, and then if it happens, again real soon, you know that you are running out of toner.

Open the printer cover and pull out the toner. Shake it a few times and put it back. Try to print and see the message is clear.

You did not provide the printer model. Now, did you try to replace the cartridges with ORIGINAL ones? Even empty ones will do, just to test if they are recognized by the printer. (ONE cartridge will suffice for this test.) If the printer will recognize such a cartridge (even an error msg. will serve as 'Recognize'), you know what I already know: never look at this vendor and his products again...

I received paperwork in my shipment that stated your printer will give you an "empty" notification, because the little computer chip on each cartridge will not work correctly after being remanufactured. There were also instructions on how to bypass or ignore the "ink level warning" on the printer if that warning doesn't allow the printer to print. Give it a try printing a sample page or two. My replacement cartridges have been working just fine. Good luck!

I would buy a new one. This printer is pretty old now. It's not worth reparing.

Another trick is to take out the toner cartridge and shake it (horizontally) back & forth to re-distribute the toner inside the cartridge. I have routinely gotten several hundred more pages out of toner cartridges after the 'replace toner' message appears !

I had a similar problem. Apparently, the printer circuitry is able to sense that this is a "not new" toner cartridge. I ordered 4 of these and had this same issue with 3 of them. Sometimes, I was able to get rid of the error by unplugging the printer, but soon the error came up again making printing impossible. I even tried some instructions I found on the www for resetting a Brother toner cartridge, this too, helped for a while. I don't have the time to waste. The real Brother cartridges are available on Amazon at a great price and at least one of the box office stores is now price matching Amazon. My condolences! I had a similar problem.
