The jet array is bonded to a cast aluminum ink reservoir. The reservoir supplies the
molten ink to the jet array. Heaters in the reservoir and the jet array maintain the ink at
a temperature of about 140
o
C for printing.
X-Axis or lateral movement of the printhead is accomplished using a stepper motor
driving a fine-thread screw system. The printhead, mounted to the X-Axis shaft,
moves laterally across the surface of the drum.
To find the printhead home position, the X-Axis system drives the printhead in an
open-loop. The printhead is driven against the left printer frame for a few seconds,
and then reversed a set distance. A tension spring links to the printhead’s left shaft,
and provides a preloaded tension so the printhead moves smoothly.
