Re: Yellow will not print

Use a original brother ink cart. Do the cleaning twice. If you don't see any yellow blocks at all the printhead is crashed and can't be fixed anymore

Bad print-outs of yellow

The first step is to run the cleaning procedures on the printer, and then if the color is still bad, try replacing the yellow cartridge. Cleaning the heads usually clears up most problems.

Yellow ink will not print

On the Brother MFC series printers it uses remote ink trays as you will know, instead of having print heads directly on the ink cartridge. Whilst this approach makes it cheaper to produce the ink, and easier to change the cartridge, it can make it difficult to clear clogs.

There are several things you can do which may help, but B. and C. are at your own risk. All steps assume you have a new yellow ink cartridge.

A. In paint or another program, create a full page yellow image and keep printing it out. See if it gets any better after each print. If it does, continue until it seems to be working fine.

B. If you can manage to get to the print head, you can get a cue tip, dip it in rubbing alcohol and gently clean the print head. Leave 20 minutes to dry, and then do step A. again.

C. (AS A VERY LAST RESORT AT YOUR OWN RISK. THIS IS GOING TO RUIN YOUR YELLOW INK CARTRIDGE SO USE AN OLD YELLOW ONE IF YOU CAN) If steps A. and B. fail, you can put a "little" rubbing alcohol in the Yellow Ink Cartridge, and keep trying step A. If Yellow starts printing again, swap to a yellow cartridge that does not have rubbing alcohol in it. You are now going to have to cycle through many pages to clear the rubbing alcohol from the ink lines.

Note that if you keep cleaning the cartridges, it is going to use a lot of ink, and may actually hinder solving your yellow ink problem.

Good uck

Replaced Yellow print cartridge and still get the message

This is a common problem with compatible cartridges where the chip on the cartridge is faulty, missing or is not making contact correctly with the printer cartridge connectors. The first thing to do is make sure that the plastic seal has been removed from the chip and that it is free of any residual adhesive etc. You can clean this with a cotton bud soaked in isopropyl alcohol or VCR tape head cleaner. DO NOT USE SURGICAL SPIRIT or any other cleanser as this will either leave a residue itself or damage the plastics and rubbers in the printer.

Once cleaned reinsert the cartridge and try again. If this is still unsuccessful the best solution is to return the cartridges to the vendor where you bought them and get another brand of cartridges or use genuine original cartridges. When you find a reliable manufacturer of cartridges, stay with them. Don’t forget to clean the print head and realign & recalibrate the printer at every cartridge change for optimum results. Also make sure that you use high quality paper for the best images results.

If you have colour or photo paper loaded in the Main tray when you align the printer, the alignment might fail. Load unused plain white letter or A4 paper into the Main tray, and then try the alignment again. If the alignment fails again, you might have a defective sensor or ink cartridge.

My printer won't print yellow even when I replace the cartridge.

Desperate measures!

I have a PIXMA MP 750 and months ago my yellow ink stopped printing. I was only able to use the printer for black and white printing. Every once in awhile I would try multiple deep cleans, new ink cartridges, etc. etc. I talked to the very unhelpful folks at Canon who suggested a new print head ($70), but they couldn't guarantee this would actually work. They really thought it would be best just to buy a new printer.

Although I was feeling bad about adding yet another cheap printer to the landfill I'd pretty much decided to get a new printer. As a last resort I decided to use a suggestion I came across (at to run hot water through the print head. It was easy to remove the print head (check your manual). I propped the head up in my dish drainer and ran hot water straight from the tap first through the end with the little circular parts and then through the end with the metal strips. I eventually used boiling water from the kettle.

As I poured water through one end I started to see yellow ink coming though the other end so I figured the ink had dried in the head. I kept pouring water through (from both ends) until the water ran clear. I dried the print head, put it back in with the cartridges and VOILA! after MONTHS without yellow ink it's working beautifully again!

If you've tried everything else and feel desperate enough to buy a new printer you might want to try this and report back.

I keep getting an error message- unable to clean....I just bought and installed new ink cartridges, and the machine is still having trouble - I cannot print at all now. There seems to be no way to clear...

The waistinktank has to be replaced. DO NOT only reset the code but change the waistinktank! Otherwise ink will flow into the machine and will cause serious damages!!!!!!!! See link how to do that:

Cannot get yellow to print

I had the same problem with the yellow cartridge. Yellow quit printing, put in a new yellow and still would not print yellow. I had a help file, don't know where I got it, but it suggested replacing the black ink cartridge also, even though the black wasn't low yet. Replaced the black, ran a few nozzle cleans and everything worked fine. Don't know why. Try it
