Canon ink cartridge cross contamination

[PC Medic]

Hi guys;

I'm not sure the problem is the printer head but I guess it is. If
this is the problem would my i850 just go dead on me. No power at
all. I had just finished refilling my cartridges and when I came back
it went on and few seconds later just died.

Anything I can check. The ink cartridges are parked on the right side
and I have no access to them.

Not likely the printhead cause this, but if you have not yet done so,
disconnect the power cord for 30 minutes and then plug back in to known
working outlet. If still no power then power supply or NCU has most likely
failed.

Obviously with the thousands of the i850s/i860s Canon has sold, I know
I'm not the only one to experience this.

I also experienced cross-contamination in my i560 however mine was
magenta into the yellow cartridge. I was using 3rd-party cartridges
too. A printhead replacement fixed the problem and I've continued to
use the same replacement inks. We'll just have to wait and see if the
contamination issue reappears.
