Ink loader
Warning Even when the printer is turned off, AC line voltages may be
present at the printer heaters while the printer is plugged into AC
power.
1. Turn off the printer and remove the power cord. Allow the ink loader
to cool.
2. Remove the left- and right-side panels and the top panel, as explained
in the earlier topic, “Cabinet panels and covers” on page 8-4.
3. Disconnect the two wiring harnesses leading to the ink loader. One
leads to the power supply, the other leads to I/O board 3.
Caution Be careful not to break the ink-melt elements of the ink loader; they
are made of a fragile ceramic material. The ink melt elements may
break if you try to remove the ink loader with the printhead in the
print position.
4. Make sure that the printhead is in its full tilt-back position. If it is not,
unlatch the tilt cam gear and rotate the process motor clockwise until
the printhead is tilted back.
5. Remove the two screws securing the ink loader to the printer’s frame.
Lift and remove the ink loader.
