Initial Actions
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.
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.
Do not tilt the printhead excessively while warm. If possible, allow adequate time for the ink to
solidify before removing the printhead. Once removed, rest the printhead on the screws that
secure the lower (slave) circuit board.
The video cable (striped and labeled A,
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.
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.
• Check the wiring harnesses leading to carriage drive and sensing components. Focus on
areas above and behind the umbilicals.
• Check for damage or debris that restricts carriage movement.
