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 handle or attempt to clean the wiper blade. Wiper blade contamination can damage the
printheads.
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.
• Check the harness leading to the horizontal wiper motor.
• Check for damage or debris that restricts horizontal motion.
• Switch off, then switch on the machine.
Procedure
Cheat the front door interlock. Move the marking unit into the maintenance position, GP 6 to
observe wiper motion. Enter dC330 code 91-025 to run the HM horizontal motion motor,
MOT91-025, Figure 1 . MOT91-025 runs.
