Check the Power Source
The printer will au tomatically power down after a configurable period of
inactivity. Activity is either sending data or pressing a button. The timer
resets during printing. You can awake the printer either by sending data or
pressing either the Forward or the Reverse buttonontheuserpanel.
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
thetableonpage38foranerrormessage.
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 (internal bat-
tery, vehicle cable, or ac). If neither of these steps “wake” up the problem
printer, then return the printer for service.
Vehicle cable: Attach the printer to another vehicle power cable.
AC power: Plug the printer into another outlet.
Large Print Jobs
Printing large files with 15 pages or mor e can cause lost data issues because
of limited printer buffer size and time out length on the mobile computer.
To prevent problems, you can adjust the time out lengths on the mobile
computer. If you encounter a problem concerning large print jobs, contact

Printer Cold-Boot
Should you need to reset the Fixed Mount Printer, simply remove power
from the printer, wait a few moments, then return power to the printer.
Self -Test
Note: Each time the printer is powered up, it reads flash values into RAM.
As long as the printer is on and awake, it updates those values in RAM.
When the printer is powered off, or f alls asleep, the values are written into
flash. If power is disconnected instead of the printer being powered off or
falling asleep, then updates in RAM are lost.
Press and hold the Forward button through a form feed (more than five
lines). If it is still held down at the end of the form feed, it prints the self-
test. Internal tests are performed and a 1-page report is printed. This re-
port provides helpful tips in diagnosing/troubleshooting printer problems.
Note: You can abort the self-test by pressing a button while it is printing.
