Hi John, it’s not that easy to get the printer to just use the eBK cartridge, because it depends on the application your using and not the printer driver alone, its complicated, but don’t be tempted to run the printer with a dry BK cartridge.Since my BCI-6 Black cartridge has run out and I'm waiting for ink, I wonder if I can set the Canon Pixma ip5000 to only use the BCI-3eBK cartridge.
