Power Switch
The power switch is located on the bottom front panel of the printer. To apply
power, place the switch in the | (On) position. When you first power on the
printer, a series of initialization messages will appear on the LCD (Liquid
Crystal Display) on the control panel.
To remove power, place the power switch in the O (Off) position.
Powering On the Printer
When you power on the printer, it executes a self-test. During the self-test, the
LCD momentarily displays the DPI resolution (203 or 305 DPI) of the installed
printhead. The default power-on state is online. Once the printer has
successfully initialized, the ONLINE status indicator light illuminates, and the
LCD indicates ONLINE, the printer model (SL4M/T4M), the printhead installed
(203 or 305 dpi), the communication interface, and the emulation selected.
If there is a fault during the self-test, the FAULT (!) status indicator flashes,
and a fault message appears on the display. The alarm may also sound, if
configured to do so.
