The LED Print Head
cables are easily damaged. Make sure you
unlock the board / head connector tabs
before you remove / reinstall the head
cables. Damaged cables will cause errors
on power up.
As you can see, the cable at the right has 3
damaged connectors – and the only
solution is to replace the damaged cable.
There are 20 wire harness cables to
disconnect.
Gently unplug all harnesses and cables
from the main logic board.
NOTE: Pay attention to how the
wires are routed to and through the
card cage for re-assembly procedures.
