Frequently Asked Questions


Why is it not a good idea to install used ink cartridges on the Canon PIXMA MP640?

Installing used ink cartridges on the PIXMA MP640 may cause the nozzles to clog and the machine will not be able to accurately detect when to replace the cartridges.


Why do the color ink cartridges on my PIXMA MP640 run low on ink even though I rarely print in color?

Even if you rarely print in color, your printer still consumes color ink when printing a black-and-white document or when it is set to print only in black and white.

If your order is below $30 and shipping to any of the 48 contiguous states, a standard shipping fee of $3.95 will apply. But if it is outside these states, then shipping cost would be $24.99.
