Black Ink does not print...I've tried cleaning the jet, replacing the ink cartridge, cleaning the cartridge intake....but, still no ink is flowing for some reason...

The printer requires both cartridges to have ink before the printer will initialize and operational. Even if you are only printing black and white both cartridge have to contain ink or the printer will error out. This is standard on all ink jet printers from every manufacturer. You will have to get ink before you can print.

yeah it is suggested that you may go for head replacment

Are you able to make copies using the Black Ink?

Are you sure there is enough level on the black ink cartridge.. if does try to do "print head clean up" if doesn't fix the problem consider to replace the black ink cartridge

I had the same problem and was told by the store that sold it to me that some printer manufacturers do this on purpose as they make their most money on the ink they sell not the printer. I got rid of mine and purchased an ink jet black only printer as this is all I need anyway. A lot cheaper to use.

make sure inck is in wright

try to find if the printer has a resetter tool online canon ink cartridges

There are a few things here that will do this. One is the cartridge is a smart cartridge and unless you reset the chip it either won't print or shows low. If you filled it before then this shouldn't be it. If you have refilled the cart more than a few times they sometimes just stop. This is either the ink has jelled inside or the little feeder sponge is dried out. If you changed ink brands sometimes the ink reacts with the old stuff and jells.The other is the jet or any feeder tubes are plugged with dried ink. Usually happens if you haven't printed for a while. You can try running the cleaning cycle and it will take quite a few of these sometimes before it starts working.

There are a few more tricks for cleaning such as using white vinegar to dissolve dried ink but that's a bit of the messy side sometimes. Usually we have just had to buy a replacement cartridge after spending the time on this. We eventually just got rig of our ink jets and got some of the cheaper color laser printers. Wish we had done that sooner.

The problem is not with the ink-cartridges. You've proved that, by swapping BLACK cartridges.

The problem is that the ink-jets that spray the BLACK ink onto the paper are clogged.
Thus, no BLACK ink reaches the paper.

Open the HP Printing Assistant, and open Utilities, and run a few "print-head-cleaning" cycles, to try to unclog the print-head.

Run a few "print-head-cleaning" cycles, to get the black ink flowing through the ink-jets inside the print-head.

Some printers REQUIRE an "alignment" step every time you change the ink-cartridges.
It only takes a few minutes, and it prints one or two pages of paper.
