SOURCE: Black 3ek cartridge not printing
I had the same problem before with 3e black ink. It simply does not print too, so what I did if i get to print black and white i will set the characters into dark gray! it looks like draft printing but the things is it can be printed.. I tried to do every instructions available but to fail. I almost dump it till I decided to set it aside for a while. After a week I tried using it again, and it functions well. I guess the printer just want to say, "HEY BUDDY, GIVE ME A LITTLE BREAK!"

SOURCE: Print Cartridge Problems
I just replaced both the black and color cartridges (empty) with new replacement cartridges - Office Max brand. I couldn't get any e-mails or documents to print, although I could get ink on paper when running the Nozzle Check and Print Head Allignment. That doesn't make sense!
I e-mailed Canon Tech Support and was told to use only Canon cartridges. I bit the bullet, went out and bought another black cartridge - this time Canon brand, installed it ,and my printer now works - including color printing.
The color cartridge is still office Max brand. My printer now says I have black ink, but still says the color ink is low (even though it's full).
Conclusion: The Canon printer only works properly with Canon cartridges!

I had this problem several times, had to buy new print head until I found that to clean it you should use ammonia. It really worked for me. You should really try ammonia it does work.
