Chapter 2 The POWER Switch
The Secondary Control Panel is behind the front door assembly below the
Primary Control Panel. It consists of UP, DOWN, PREV, and NEXT arrow
keys to navigate through the printer configuration menus, and CLEAR, PRT
CONFIG, JOB SELECT, and ENTER keys for performing specific functions in
the offline mode or within the printer configuration menu.
The POWER Switch
The POWER SWITCH is located on the back panel of the printer, in the
bottom left corner. Placing this switch in the ON (1) position applies power to
the printer. An illuminated LCD Message Display indicates the printer power is
ON.

Powering On The Printer
When you power on the printer, the T4204 executes a self-test. The default
power-up state is online. Once the printer has successfully initialized, the
ONLINE status indicator light will go on, and the LCD indicates the
communication interface selected and the type of emulation installed. The
interface is indicated by PARL for parallel and SERL for serial.
If there is a fault during the self-test, the ONLINE status indicator flashes, and
a fault message appears on the display. The alarm may also sound, if it is
configured to do so.
