Hello, I did a quick search and came up with this useful blog which, if you read some of the responses to, gives some links to some very useful info. Be aware, that as well as filling the cartridges with ink, you will have to program a chip on each cartridge with something called a chip resetter which, if you read the responses, someone mentions how-to-do and where-to-get and how much it costs.

Lights do not come on to show which cartridge needs changing

The MP640 uses the PGI520 and CLI521 cartridges.
When you lift the top and the carrage moves to the middle all full cartridges should be lit up. If the light is off on any/all cartridges it means they are empty. If the light is flashing it means it is running low.

Each cartridge has a clip on the back of the cartridge. Push this clip towards the cartridge and it releases the cartridge for replacement.

On Canon MP640 blue doesn't print

take out the new cartridge and you will see contacts where the cartridge will sit. you will have to pull SLIGHTLY towards you the contacts so that when you sit in the cartridge the idea is it will have perfect contact so that signals will relay through the equipment.

MP640 - After changing the ink-cartridge ,a message appear. "The following cartridge is unknown", U043

I would try opening the printer, make sure the ink cartridge is fully seated. Once that is checked, unplug the printer, wait a minute or so, then plug the printer back in and try to turn it on. If the problem persists, then try a new ink cartridge. If that doesn't work, there is something major wrong with the printer itself, and will be beyond anyone but a Canon repair facility to repair.

Changing ink in mp640

Turn the printer on.
Lift the cover to expose the print-head mechanism.
Wait a few seconds, and the print-head will slide to a position from where you can remove the ink-cartridges.
Look on the inside of the cover -- there may be instructions on how to change the ink-cartridges.

Will PIXMA MP640 print with an empty cartridge

No, it will not. I have this printer and last week I ran out of cyan. Even though i only wanted to print black and white documents the printer would not print anything until I replaced the cyan cartridge.

Just reinnked my black cartridge for a Canon mp210 (cl37 modle cartridge) and I get a reinking error on the panel. Tells me there is no ink. Do I need to let the cartridge settle for a while OR is there a...

No, what you need to understand. Most printer companies have a chip installed in the ink cartridge. This chip is linked to the printer’s software. It knows you have refilled the ink because your putting the same cartridge back in. To get around this you will need at least two in cartridges. When one has emptied you install the second (refilled) cartridge. (Fooling the software). Some you need a total of three cartridges.
Remember printers are cheep compared to a few ink

This should help in the long run.
Good Luck!
