Canon Pixma TR4722 won't print yellow

HannaMo — Thu, 18 Jun 2026 21:18:26 GMT

I have a the TR4722 printer that is less than 3 month old, which functioned beautifully --- until it did not. The images remained sharp, but it quit printing full color.

I have --

run the nozzle check
cleaned the nozzles
deep-cleaned the nozzles
run the head alignment
roller cleaning
bottom plate cleaning
changed the color cartridge
run all the diagnostics, alignment, and cleaning twice more

without changing anything.

I do use the correct Canon ink cartridges.

I am pasting a sample of the print test page after nozzle cleaning below. My resulting print page (both before and after all my attempts) shows exactly what is below EXCEPT where I have drawn the red arrow is BLANK.

My Black is printing fine and aligned, the Cyan and Magenta are printing fine -- both in dark and light, my pale Yellow line is fine, but my rich Yellow line (where I have drawn the red arrow) is blank because my printer will no longer print Yellow in color copies.

How do I solve this?

The nozzle check indicates a faulty color cartridge. The printhead is on the cartridge.

I can see why you might say that; however, the printer was working perfectly with a Canon color cartridge in it. Then the printer quit printing yellow, and the nozzle check indicated as I described. And a new Canon color cartridge failed to print yellow, and the nozzle check indicated the same lack-of-yellow fault. Therefore, it seems difficult to believe that a working (and full) color cartridge would have a fault yellow nozzle AND THAT the new replacement color cartridge would have exactly the same nozzle fault at yellow.

Ideas?

Did you print a nozzle check that shows no dark yellow at all? It is on the image you posted so I assumed you printed one without any dark yellow at some point? A missing color usually indicates a clogged or bad print head and the print head is on the cartridge, which usually indicates a problem with that cartridge when print head cleaning fails. I had a similar issue with my MG3620, printing cyan, the dark printed but not the light, I cleaned it, deep cleaned it, and it still did not print. I replaced the cartridge and it did not improve, the third cartridge worked. I can only assume that if it is not the cartridge, the printer cartridge chip reader or some other component has failed and it does not see the yellow any longer.

Thank you so much for your answer AND thoroughness.

The image that I posted was an online image indicating what is supposed to be there. My sheets come out exactly correct EXCEPT THAT the dark yellow area (indicated by my drawn red arrow) is blank.

The nozzle report has printed exactly that way (dark yellow missing) before I changed the color cartridge and after.

I do hear you about you encountering two different bad cartridges and having to go to a third. Wow!

However, since my PALE yellow prints correctly, is that the nozzle? Does a print cartridge have TWO nozzles per color? (One for pale and a different for dark?)

Given that my pale yellow works fine, are you still leaning to a bad cartridge nozzle?

The actual print head on a cartridge has many nozzles far more than just the colors you see on a nozzle check. Notice the black on the check? each dot color or black is made by a separate nozzle, up to 1200 of them. That is why a clogged nozzle or nozzles may make blank spaces in one of the colors, not the whole color missing. If the whole color is gone it is usually caused by a failure of the cartridge to release any ink at all from that section of the cartridge.

Thank you for bearing with my incredulity and educating me! I bought yet another box of ink cartridges and proved that you were right.

I wonder how many (as I was prepared to do) return the printer when the 2nd Canon cartridge does not work. Amazing!

Since you have worked through this, I wonder if you advice on where / how to buy cartridges? Is one retailer's product any better than another? Or does the regular size tend to perform better than the XL?

I buy my genuine Canon Cartridges from Amazon, I make sure Amazon is the seller and the shipper. The XLs have more ink as you know. I have two printers, the cartridges for my IP8720 just contain ink, Amazon, unlike the Canon site will sell the whole color pack except for gray. The cartridges for my MG3620 have a built in print head. The mistake I made with the MG was buying remanufactured Canon cartridges from a third party, and many of those were defective. Now I pay the extra money for true Canon XL cartridges. I tend to buy a 2 pack even when I need only one, I will use them both eventually.
