my yellow cartridge is contaminated!

[Vince]

how the heck did this happen? although i have recently refilled black, cyan
and magenta. i haven't touched the yellow cart at all, and yet the color in
the tank is dark and murky.

does anyone have an explanation of why the *only* cartridge i didn't refill
is contaminated!?

Please include what type of cartridge and for what printer you are using.

 

[Vince]

the printer in question is a canon s520.

This is an original Canon Cartridge that has never been taken out of the
printhead since you installed it?

If yes..........maybe there is a fracture in the cartridge that allowed
algae to grow or some contaminant in. Other than that, The Enterprise beamed
Spocks blood sample to your cartridges.....
