Ink+Used+Change+Printhead

=How much ink is used when changing the printhead?=

According to Trevere, "The ink usage for filling the new printhead (and aligning, which used a trivial amount) was about 10-11 ml per color." Total ink used was about 60-71 ml (each printhead handles 6 of the 12 colors), or one half of a regular size ink cartridge worth. Cost would be approximately $38.00.
