4 Model Cooling Fan Inspection
Inspectionproceduretoverifythatthemodelcoolingfansareoperational.
4.1 Procedure
1. MakesuretheprinterispoweredON.
2. IntheAlaris30software,selectMaintenance>Actuatorsand
Sensors.TheActuators&SensorsControlwindowopens.

3. IntheFanssection,clickOnfortheModelFan(iftheModelFansare
currentlyoff).
The UV lamp and head driver cooling fans do not require inspection, since they
contain speed sensors and their status is routinely checked by the printer.
