Discuss > Does anyone calculate their actual ink usage?

Just curious if anyone is calculating their actual ink usage per print. How does it compare to the published figures in the user manual?

I just ran an 8.5x11 test print on our Epson 7900. In the job history in the printer, it said that the print used 1.2 ml of ink. Using some algebra (some people are probably cringing at the sight of that word), I figured out that the same print would have used 1.85 ml of ink if it were a 12x12 print (or 1 square foot). The cost per mL on ink for a 350ml cartridge is $0.39 per 1 mL of ink. With that being said, the same print with the same settings would have been $0.72 a square foot in only ink.

I know its a lot of numbers, but to sum up, my prints will use 1.85ml of ink per square foot and cost $0.72 a square foot as well. The settings I used were both the Premium Glossy paper setting and profile, 720x1440 dpi, and the print covers about 95% of the page.

I also couldn't find anything that has an exact number on how much ink the printer should be using. Does anyone else have this info?

Most professional Epson printers (designated as PRO series) have an ink usage counter in the menu. I know on my Epson Stylus PRO 3880 you can access the counter by going to Menu > Printer Status > Usage Count.

What is really cool is you can also look at Job History and see exactly how much ink was used and what size paper for a particular print. That is found at Menu > Printer Status > Job History and scrolling through to the job you are looking for. Some simple math will provide an exact ink and paper cost for a particular print.
