Wiping of the print head occurs when the cartridge moves across the wiper (in either
direction). The printhead is wiped (twice) when power is turned on, when beginning a
print job (after the print head has been capped for more than four minutes), after six
pages of continuous printing, after 50 seconds of printing on the same page, and after
purging or changing the ink cartridge.
