Sleep Mode is a low-power mode used in devices such as computers and mobile phones.
Zebra® has adapted the Sleep Mode concept to reduce power use and extend battery life on printers. The feature first shipped on the ZQ500™ printer series. While in this mode, the printer’s LCD display screen will turn off, and all communication interfaces will be shut down.
On the ZQ500, just before the printer enters Sleep Mode, the LCD display will show a ‘SLEEPING’ alert to inform the user. While the printer is in Sleep Mode, the power LED will slowly and continuously pulse on and off. The color of the printer’s power LED while in Sleep Mode will depend on the printer’s charge state:
• Green on battery power
• Amber if charging
