Is the Rechargeable Li-ion Battery installed?
Is the AC Adapter connected to the printer?
If not, install the Rechargeable Li-ion Battery or connect the AC Adapter to the printer.
Is the USB Type-C® AC Adapter connected to the printer without the Rechargeable Li-ion Battery being installed?
Because the USB Type-C AC Adapter is used only for charging the Rechargeable Li-ion Battery, the printer does not turn on or print without the battery being installed.
Make sure the Rechargeable Li-ion Battery is installed before turning the printer on.
Is the remaining charge in the Rechargeable Li-ion Battery low?
If the remaining charge is low, charge the Rechargeable Li-ion Battery.
If the problem continues, contact Brother customer service.
