My company lives on the (discontinued) Canon Pixma Mx410 since it is so refill-friendly. We've had two in the past 10 years, and refilling is extremely cost effective ($80 liter bulk ink) but our remaining one is now experiencing the waste ink error.
The first one that experienced waste ink full error, I I managed to take the printer apart but probably broke it doing so, and didn't know how to factory reset it anyway. Now that our remaining one is on waste ink error, I can find no instructions for cleaning out the waste ink or resetting the printer on the web after days of searching.
And I love this printer. We don't even have to take the cartridges out of the printer to refill them; just shoot a syringe in them while they are still in the machine, cover the hole with a snippet of duct tape, and keep printing. So anyone who can help me take it apart, clean the waste ink, and RESET the printer to factory reset, you'll keep a small geeky grandma business going. Ill send cookies!
