Disconnecting The Ac Adapter - Oki PT390 Guia Del Usuario

3-4. Disconnecting the AC Adapter

To unplug the AC adapter cable, grasp the connector as shown in the
picture below and pull it out. The lock mechanism of the connector will
then disengage, and the cable can be unplugged easily. Conversely,
forcibly pulling on the cable itself may damage the connector.
Note: Before disconnecting the AC adapter, switch off the printer and all devices
connected to the printer, and also disconnect the power cable of the AC
adapter from the outlet.
