Normal circumstances isn't printing over 200 letter-size prints at high quality on pro-gloss photo paper with pretty heavy photo coverage.
9 tanks of ink replaced, including 2 of photo magenta (and here I thought 2 tanks of photo magenta would get us through the weekend). Out of photo magenta (including the one in the print head that's waiting to be replaced so the job can continue), photo cyan and red. Down to 1 tank of green. Plenty of cyan, magenta and yellow. Tons of black still in inventory.
Maybe I'll just invest in a continuous-flow system.
