Keep the Mobile Work Station’s power switch ON when continuously operating the MWS and/or printer(s). If the MWS will be unused for extended periods of time, turn OFF the Mobile Work Station’s power switch.
The MWS’ power switch controls the power to all printers. If using more than one printer on the MWS, manually turn OFF each printer’s
power switch.
