Perform the Shutdown procedure at the end of productive session before long time idle state (overnight or during the weekend).
See:Print a Nozzle Check for the procedure.
See: Automatic Printhead Maintenance (AMS)
Do an AMS when:
more than 2 nozzles outs exist in a single printhead
2 or more adjacent nozzle outs exist in a single printhead
Power and compressed air are required in periods of inactivity so the printer can perform automatic functions to maintain its operating state. These functions are necessary to guarantee optimal printing performance.
When the printer needs to be shut down for an extended period of time (more than 14 days) please contact your local service representative so that the ink can be properly flushed from the system.
