Canon Pixma MX300 won't print black anymore! How to fix?
I have used "refill" kits in the past and for the time and effort involved you might just try finding a local retailer that will give you credit for the empty cartridge to replace with a professionally refilled one.
The problem with refilling the same cartridge over and over again is that they will, eventually, need to be replaced. I would suggest that you
1 - Make sure there is nothing plugging the hole at the top of the cartridge to allow air in, which is needed to let the ink flow out.
2- Install another cartridge and you get the same problem, then it narrows your fix to something with the printer.
3 - If it is the printer, I were rubber gloves and use "denatured alcohol" and a rag (no not use anything with paper as it can tear and leave pieces inside causing the printer to jamb) and after removing all of the cartridges wipe down anything that I can reach inside the printer.
4 - Although you have tried the DEEP CLEAN, if the none of the above works for you, try the NOZZLE CLEAN. If you are still having a problem then either re-post the problem or doe a Google Search listing the model of the printer you have, you may find out it is a problem that others have experienced and there is no solution.
