Inkjet Printer Forum / Ink Jet Refill Forum

Hello!
I have a fairly new Canon PIXMA MX320. It’s an inkjet multifunctional (Printer, Scanner, Copier and Fax). I have refilled the cartridges many-many times. So although, I get message for the ink being (supposedly) empty, I can print without problems. However, when I receive a fax, it doesn’t let me print it! Also, when I send a fax, it doesn’t let me print the report at the end! This is very annoying!!! The messages that are displayed on the machine’s screen are "Replacing the colour ink is recommended" and "Black ink is running low". Any ideas of how to get round with this?
Thanks a lot!!!
