When I print, paper comes through but it's blank! Thought I was out of ink, so I went and bought another toner cartridge. Same thing!

Hi,

Please double check that the nozzle of your printer is clean. Also, please run test prints with different document to check for any change to the issue afterwards.
And you'll want to restart both your printing source (ie computer) as well as your printer before attempting another test.

Also, please check that toner that you're using isn't a 3rd party toner as printer companies have updated their software to block these from working with your printer.

Thank you.

buy a new one

I guess it FixYa didn't accept my (very long, but totally correct) solution that I took the time to type. Because I refused to "sign in".
Here's the short version. Load Paper. The same thing happened to me. I replaced the toner cartridge with a new one (because of a FLASHING red light for several weeks) after the red light went to STEADY red. But it still would not print. The paper was "out". When I'd refilled the paper-tray, it printed fine. I had just ASSUMED that the steady-red light meant toner was finally OUT. WRONG! That steady-red light had nothing-to-do with toner; it meant "you're out-of-paper". Don't get confused like I did. Refill the paper-tray. Then take that expensive NEW toner cartridge OUT, and put the OLD toner cartridge back in. And keep using the "dregs" of the toner out of the old cartridge for several more weeks. And DON'T get confused by the paper-is-out condition making that red light STEADY.

The toner is dry ink that sticks to the paper, and then gets melted into the paper. When the cartridge that holds the toner starts to run out, then the "low toner" condition occurs.

Keep using the printer until the toner-cartridge is empty, and your printed pages come out as "blank". Then, replace (or refill).

I think the ink of the toner is finish or toner is not place at right situation. Please check toner ink and position of the toner.

Check the print cartridge. Open the printers top cover and find release lever for the ink cartridge. Lift out the cartridge and check the jets (copper coloered foil with holes) for blockage. New cartridges have a piece of tape over the jets which must be removed before installing. If blocked with dried ink, dab gently with paper towel and rubbing alcohol. Dry by dabbing on paper towel. Other things to check are: Incorrect cartridge, empty cartridge, and cartridge not snapped in all the way. The cartridge that comes with the printer usually is only partly filled and runs out earlier than normal. You could always try a new cartridge which you will need eventually anyway.

Good luck,

it may be many things, here some thing to try:

the ink or toner is contrammed with foreign liqued like oils, water, bad ink, bad toner cartridge,
oil, water, ink toner inside the ink itself
oil from a human skin my have came in contact with refill of ink or toner cartridge, cleaning solvent to clean the cartridge, needles for hte ink or toner cartridge, water in the ink or toner cartridge, steam or vapors of some kind, compress air can or air compressor will spread water solution, the freon is used in compressed air can thats way they get so cold when you spray the can.

paper may also be wet some how try new and different brand of paper.

Try checking the ink cartridges and make sure they have ink in them or it will keep printing blank pages. Then try printing a test page by going to control panel, clicking on printers and faxes and right clicking on your printer and going to properties. Then go all the way down to the bottom of the page and click print test page. It will clean the printer cartridges and align them to print correctly. It should work after that.

make sure the paper is off the ink cartridges

Step1
If you're setting up the printer or changing the toner or ink cartridge for the first time, double-check the instructions to make sure that you installed the cartridge correctly and, for new printers, that you have removed all the pieces of cardboard or plastic packing material. 
Step
2
Check to see whether paper is feeding from the paper tray. If it's not leaving the tray at all, try feeding a page manually (if that's an option) or using a different paper tray. Sometimes a problem with the tray can be traced to a broken spring or a piece of plastic. 
Step
3
If paper is feeding from the tray but jamming in the printer, examine where the jam is occurring and then inspect the printer carefully to see if you can find what is causing the problem. A piece of paper, for instance, might be blocking the paper path. 
Step
4
If paper is feeding through the printer but coming out blank, check to see whether the printer is out of toner or ink. A defective toner or ink cartridge could be the problem.
