Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION
Do not touch the exposed face of the printheads. Surface contamination or minor damage can
destroy the printhead. Printheads must only be cleaned by a purge cycle.
CAUTION
Use care when opening the marking unit drawer when hot. Ink can spill from the ink reservoir
located at the back of the drawer if opened with too much force. Ink cross-color contamination
could also occur.
CAUTION
The video cable (striped and labeled A, PL 92.10 Item 7 ) and the wave amp cable (white and
labeled B, PL 92.10 Item 8 ) should not be interchanged at the printhead connectors. Damage
to the printhead and IME controller PWB will occur if the cables are installed incorrectly
• Check all 3 wiring harness leading to the indicated printhead. Focus on areas above and
behind the umbilicals. Ensure each harness is securely and correctly seated, refer to
GP
28 .
Procedure
Check for damage to the cables connecting each printhead. The wiring is good.
