Yellow cartridge problem

Hello,
The Magenta or RED toner cartridge should be removed and double check that you have indeed removed the pull tab located on the side of the cartridge which will remove the sealing tape off the new toner cartridge.
The YELLOW toner cartridge on the other hand if it is not new then it is perhaps empty and needs to be replaced. Another option is to remove the YELLOW toner cartridge from the machine, Tap it and shake it side to side to loosen the toner that is in it, and replace it back into the machine, this will usually make it start to work again!
Good Luck!

Hello,If they are vertical lines then the most common reason for this is that containers for the waste toner of the magenta and yellow cartridges are full. This is not a common problem if you use original HP cartridges, but if you use compatible or refilled cartridges it happens. If you get the magenta and yellow cartridge out and look at the the green OPC drum you would see these 2 lines. You can carefully shake the cartridges 5-6 time HORIZONTALLY and the problem will probably disappear for a couple of pages. If this happens then you must replace the magenta and the yellow cartridges. Post back results here. Hope this helps

It is not possible to print while an empty cartridge is in the printer.
Try shaking the yellow cartridge and try printing again.
There may be enough toner left for a few more pages.

need to put a new yellow printhead.

Look through the menus on the printer for a setting for "Low Toner" -- the choices of what to do are usually either "continue" or "stop" or something similar (my 2430DL has this option setting) -- set this option to "Continue".
My 15 year old HPs also have a similar setting. However, this will keep it printing when the black runs out, so you will need to check your print production run visually as you go along to make sure the quality is what you need

Only if the page your printing needs the yellow.
I change the print options to Greyscalle and it will only use the black and ignore all the other colors.

Try taking your yellow cartridge out and giving it a shake. Also make sure you've removed all the plastic tabs from the cartridge, and test to see if there is any colour coming from it by pressing a damp paper towel against where the ink shoots out. If it still doesn't work I would simply return the yellow ink cartridge to where you purchased it for a new one.

Not sure why you're going through the yellow toner so quickly. You might try pulling it out and shaking it some to re-distribute or loosen the toner inside.

Yes you can override the cartridge out of toner print halted problem. This is located in your User's manual and is stated as:

Replace Supplies feature
The printer has three options for low or exhausted supplies status:
● STOP AT OUT (the default setting): The printer continues printing while a print cartridge is low.
When the cartridge is out, the printer cannot print.
● STOP AT LOW: The printer pauses until you replace the low cartridge.
● OVERRIDE AT OUT: The printer continues printing even after some supplies have run out.
To set the Replace Supplies feature
1. Press Menu.
2. Press (down arrow) to highlight CONFIGURE DEVICE, and then press (check mark button).

6. Press Menu to return to the Ready state.

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 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.
