When printing something on my cannon mx310, why is the black ink coming out blurry on printing paper

The help desk is right but there is a way around this problem.
This printer is a color printer. The only way to print white text on black is to a program such as PowerPoint and create a black colored page and then use white colored text. You need to put white paper in your printer.
This will cause the printer to use a very large amount of black ink and if the paper is too porous then the printed text will not be clear. Make sure you use inkjet paper.

Black printer ink in Canon Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

When you go to save it or just before that you select file then go to print properties under that there should be a selection to print it in black and white.

Let us know ether way but its done under printer properties.

my black cartridge is not printing it has ink

If when you attempt to print only with the black cartridge installed but it won't print, then this specific printer requires that color ink also be installed. Typical with most inkjets.

There are several things to check
1.remove and reinstall the ink cartidges
2. press ON/OFF switch to reset the printer
3. if the printer is new, make sure all the packing material has been removed
4. Check the paper path to make sure that you do not have a paper jam.
5. If these do not clear the problem, you need to have the printer serviced.
2. 3. Remove Packing Material MX310 4. Removing paper jams MX310 5. The MX310 may require repair
