Check The Power Source - Intermec PK80 Quick Start Manual

Check the Power Source

The printer will automatically power down after a configurable
period of inactivity. Activity is either sending data or pressing a
button. The timer resets during printing. You can awaken the
printer either by sending data or pressing the Forward or the
Reverse button on the user panel.
If there is power, the power LED turns On and the print head
moves to its home or starting position. If the printer emits beeps
and power LED lights up or flashes, observe the number of
beeps and flashes and refer to the Troubleshooting table (see
page 16), the Printer LED table (see page 13), or the PK80 Se-
ries 80-Column User's Manual p/n: 961-018-004.
If there is no reaction from the printer after pressing a button on
the user panel, or only the power LED blinks, verify that the
power cables are properly connected between the printer and its
power source. If neither of these steps "wake" up the problem
printer, then return the printer for service.
S Vehicle cable:
Attach the printer to another vehicle power cable.
S AC power:
Plug the printer into another outlet.
