They sell Image Specialists ink
There are sources on the web that tell how to
get around the chip. I would be surprised if
someone really copied the ink formula this quick.
If you'll note... the bcl-7 and the cli-8 are the same item number
"GIEBCI7 Color" They didn't copy it that quick but rather the bci-7
was released in japan but didn't make it to america... not in the same
cartridge that is... but rather in the chipped cli-8 cartridges.
But near as i'm aware, there are no souces to get around the chip, only
the printer it self will disable metering if the chip maxes out, after
three "i'm getting empty" messages.
