Re: My printer won't print yellow even when I replace the...
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 pcuser.com) 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.

problem could be due to a communication failure between one of the printheads
(cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps
below to identify and fix cartridge issues:
Make sure the printer is on.
Open the printer cover. The
print cartridge carrier moves and stops at the loading position, unless
the All-In-One is busy. Note: If the carrier does not automatically move
to the center, turn off the printer or unplug the printer from the power
source and then carefully slide the carrier to the center.
Remove both cartridges from the
Close the printer cover.
Re-brick your printer by
pulling out the power supply - black box behind the printer where the
power cord is plugged in to, and re-plug after 30 seconds.
When the printer turns on,
reinsert one cartridge first. Close the printer cover and check for any
If no error appears, reinsert
the other cartridge. Close the printer cover.
Replace whichever cartridge is
causing the error to appear with a new genuine Lexmark cartridge. Try to
print a document again to verify that the problem is fixed.
Try to contact the store where you bought the new cartridge(s) and have them replace it. You may also contact Lexmark Technical Support Center for assistance (especially if you're using genuine cartridges).
First try to replace the yellow toner cartridge. After that, try re-seating the cartridge (take out the cartridge and place it back in carefully making sure it is seated correctly). If this does not resolve the issue, clean the print heads and connections on the cartridge. This can be done by removing the cartridge and swabbing the connections with a Q-tip dipped in rubbing alcohol. Also, while the cartridge is removed, swab the connections to the cartridge that are inside the printer where the cartridge is seated.
it sounds like the printer is malufunctioning...it might be a problem with the printer head..see where the printer opens for the ink.. look at the yellow space for the ink.. remove the ink and take a cotton swab full of alcohol and clean it then let it dry and place the new ink cartridge there and restart the machine..see if it gives the same eror..if it does consider replacing the device
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.
