Testing the printer
When you power ON the SureMark printer, it runs a power-on self-test (POST). If
the POST finds no errors, the printer is ready for operation. Follow this procedure to
determine if there are errors.
Note: Never connect or disconnect the printer when power is applied (when LEDs
are ON).
1. If the printer is powered ON, power OFF the printer and power it ON again.
v If the printer is attached to the system with the EIA-232 cable or the standard
USB cable with a power brick, disconnect the power cord, then reconnect the
power cord to a properly wired and grounded power source.
v If the printer is attached to the system with the RS-485 cable, power OFF the
POS system, and then power ON the system, which also powers ON the
printer.
v If the printer is attached to the system with a powered USB cable, the USB
attached printer can be hot-plugged.
