Checking the Power Source

Testing the Printer

The printing system is composed of four basic components: power
source, printer, computer, and communications. Any one of these
components can prevent the printer from functioning properly.
Press any button on the printer control panel. If there is power, the power
indicator (green LED) turns on and the printhead moves to its starting
position. If the printer emits beeps and any of the other indicators light
up or flash, observe the number of beeps and indicator flashes and see
"Printer Failure Indicators" on page
If there is no reaction from the printer after you press a button on the
control panel, or if the power LED blinks, verify that the power cables
are properly connected between the printer mechanism and its power
source (internal battery, vehicle cable, or ac). If none of these steps
"wake" up the printer with the problem, then you need to return the
printer for service.
•
Internal battery
Check the battery and its cable by installing into a known-good
printer.
•
Vehicle cable
Attach the printer in question to another vehicle power cable or
another printer to the vehicle cable you are using.
•
AC power
Plug the printer into another outlet.
If the power indicator works properly and the printer still does not print,
then printer errors are noted. If any indicators light when you press the
Set Page button, or the printer beeps, refer to the Printer Failure
Indicators table on page 82
