1. For the not-so-tech friendly, installing ink cartridges in printers can be messy and time-consuming. Although companies such as Canon are constantly trying to make designs more convenient for all users, there are still several tips that can help new printer owners install Canon PG-40 printer cartridges without mess or hassle.
Compatibility
2. Although many printer cartridges are specific to only a few models, the Canon PG-40 printer cartridge was designed for use with many models of the Canon Pixma and even some of the Canon fax machines. As of September 2010, the Canon PG-40 ink cartridge can be used with the Pixma iP1600 through iP1800 printers, the iP2600 printer, the MP140 through MP190 printers, the MP210 printer, the MP460 and 470 printers, the MX300 and MX310 printers and the JX200 and JX210P fax machines. This versatility allows users to stick with the same type of ink cartridge over the life of several printers and allows small business offices an opportunity to buy one type of cartridge for all office printing requirements.
Refill
3. Replacing printer cartridges can be expensive and, if it is possible, as it is with the Canon PG-40, refilling is a cheaper and more environmentally friendly option. Refill the PG-40 by gathering a 10 cubic centimeter syringe with a 1.5-inch needle, a pair of latex free gloves, an MIS Yellow Drill Tool, Scotch tape and black ink. Remove the label from the top of the cartridge and use the yellow drill tool to open the vent hole that was covered by the label. Next, load the syringe with 20 CCs of black ink and inject it into the ink hole (where ink leaves the cartridge for the page.) Make sure the needle reaches the bottom of the ink tank and then slowly inject the ink into the cartridge, stopping when the ink begins to well up at the needle insertion point. Now remove the needle and clean the top of the cartridge off to avoid color contamination. Put a small strip of Scotch tape over the vent hole and poke a small hole in the tape with a pin. Now reinsert the cartridge and run up to three cleaning cycles to calibrate the printer.
Resetting the Ink Level
4. While refilling ink in a PG-40 can save money, it can also cause difficulties when using the automatic ink level sensor. Reset this sensor by removing the cartridge after the printer has been calibrated and placing a thin strip of Scotch tape on the line of gold-colored leads nearest the ink hole on the bottom of the ink cartridge. Replace the cartridge and wait for the computer to display a warning about the ink cartridge being loaded incorrectly. Remove the cartridge and move the tape from the first to the second level of leads and replace the cartridge. When the PC displays a message that the cartridge is not recognized, remove the cartridge and replace without the tape. The ink level will be reset.

Lois, unfortunately, most printers will prevent you from doing activities when the ink/toner cartridges are empty. While it my be frustrating, there's usually no way around this other than to replaced them.
You can purchase replacement ink for your Canon Pixma MX310 from most major retailers, including several online ink-related sites, such as: http://www.databazaar.com/
You'll need to purchase a Genuine Canon replacement cartridge to get the best life out of your printer. Look for a PG-30, PG-40 or a PG-50. Each of these will fit your printer. The PG-50 holds the most ink and will last longer, but is obviously a little more expensive.
Conversely, if you need the photo cartridge replaced, look for a Canon PG-31, PG-41 or a PG-51.
Hope this helps!

Select true black and white. Any other setting uses the colour cartridge to sharpen the printing.

I had exactly the same problem. I called the Canon helpdesk and apparently the PG-50 is not compatible with the MP210. I then bought a new PG-40 which works fine.

Bit annoying as I have wasted £35 or so on the PG-50. This is also a bit misleading from Canon as the PG-50 fits into the MP210 perfectly, and when you are looking at it on the shelf it looks like a long-life version of the PG-40.

But there doesn't seem to be any way around it that I have found. Just bite the bullet, write it off to experience and buy a new PG-40.
