- 1). At your next purchase of a fresh ink cartridge, write down the volume of ink that is contained within. Keep track of this value.
- 2). Keep a running tally of the number of pages you print with your new ink cartridge.
- 3). Divide the volume of ink in the fresh cartridge by the number of sheets that have been printed. Do this only when the printer is no longer producing prints at the necessary quality for your application.
