I've been refilling the Canon CL-40/41/50/51 series cartridges for at least two years now, and have had problems with them lately. When they first came around, they were by far the best inkjet cartridges with integrated print heads, at least what it comes to refilling. Not being able to reset the ink level counter was the only annoyance. But now when I refill the same cartridges for the same printer series, it seems that one out of three refills fail due to an electrical problem in the color cartridge (it's never the black one, for some reason) and I end up with error code 5 (cartridge not compatible or not installed properly). The refill might work like a charm for some time, and then stop working with no apparent reason like removing and reinstalling the cartridge or otherwise causing mechanical wear to it.
I'm sure that the problem is not in my handling of the cartridges, and also sure the same cartridge series used to work way better than this. Anyone else been having the same problem? If so, do you think it's just weird luck, a quality problem with the cartridges, or maybe some kind of self destruct mechanism by Canon to keep people from refilling?
