Procedure
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
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
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 that the ribbon cables connecting the relevant printhead to the IME controller PWB are
correctly and securely connected, and not damaged. Re-seat the ribbon cable as necessary.
The wiring is good.
Y N
