2 Printhead preparation

This process empties all the ink from the printheads and consumes a quantity of printhead flush

solution. Be prepared for proper disposal of the liquid wastes before moving the printer. Dispose of

all liquid wastes in accordance with local regulations.

IMPORTANT: The printheads have a very short lifespan if ink is removed from them. The printer

move should be executed as speedily as possible to prevent permanent loss of jets.

If the printer move will take a very short period of time (less than a few hours) it may not be

necessary to empty the printheads of ink. Use a fully charged uninterruptible power supply (UPS) to

provide battery power to the external 24VDC power supply for the ink delivery system (IDS)

vacuum. If the duration of the printer move is too long to provide battery power to the IDS vacuum,

then the ink must be emptied from the printheads before moving the printer.
