Black > Blank
A laser printer containing a new toner cartridge was set to constantly print a black A4 document until the toner ran empty and a pure white sheet emerged, unprinted. As the pages exited the printer, I stacked them face up. The completed stack of paper contains the entire contents of the toner cartridge. The bottom page is black, the top page is white, and between is the transition—demise, depletion, expiration—from black to blank, full to empty.
