Uninterrupted Power Supply (UPS) Mode

Uninterrupted Power Supply (UPS) Mode

In UPS mode, the printer receives external power which passes through the battery circuitry to the printer.
  1. Press
    Battery Control
     to ‘wake up’ the battery and check the battery has charge.
    After 60 seconds, the battery enters sleep mode. In this mode, the battery uses loss of external power as a cue to wake up and supply the printer with power.
  2. Turn printer power OFF and ON as you normally would. The printer does not require the battery be manually turned on to operate when it in UPS mode.
