Checking the Power Source

Self-Test Failure

106
Press any key on the printer control panel. If there is power, the power in-
dicator (green LED) turns on and the print head moves to its starting posi-
tion. If the printer emits beeps and any of the other indicators light up or
flash, observe the number of beeps and indicator flashes and refer to the
Printer Failure Indicators table on page 116.
If there is no reaction from the printer after you press a key on the control
panel, or only the green power light 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.
S Internal battery: Check the battery and its cable by installing into
another known-good printer.
S Vehicle cable: Attach the printer in question to another vehicle power
cable.
S AC power: Plug the printer into another outlet.
If a partial report generates and a printer error occurs during printing,
refer to the table on the next page for troubleshooting help.
If the printer does not generate a report:
S There may be a printer failure, refer to the troubleshooting table on the
next page for possible solutions.
S There may be a power failure, check the power source (internal battery,
charge cable, or ac adaptor).
