Question about Canon PIXMA iP6700D InkJet Photo Printer
I think I have come up with a solution!
When the error happens:
Open the cover and re-seat the cartridge.
Tilt the whole printer forward about 30 degrees or more
Close the cover.
This has worked for me multiple times now. I think there is a small sensor behind the contact chip that detects ink levels and when my printer is flat the level of ink is lower than the sensor, when I tilt the printer the error vanishes because the ink covers the sensor. Though I am not sure why the software in the printer determines that there are duplicate cartridges instead of just a low ink warning.
If you still can't get it try taking a standard pencil eraser and gently rub it over the contacts to clean off any oxidation, also do this to the prongs that contact the chip that are inside the cartridge carrier, They bend easily so do it very lightly.

I can't fix ti too.
BUT... I did come up with a temporary solution.
1) Turn printer off.
2) Unplug USB cord.
3) Turn printer on.
4) Then plug USB cord.
It "should" work again.

Make sure that the inks are not re-manuafactured ones with chips taken off genuine canon inks. It is possible that the wrong chips could be fitted to the wrong colours.

Are you using genuine ink cartridges? If not, then perhaps there is no microchip on your ink cartridge. You can take the old chip off your used cartridge and put it on this cartridge and see if this solves your problem.
