3.3 Connectors and Indicators
The following figure below shows the locations of connectors and indicators (1) on the eXtendo® XF
series including a detailed view of a connected DC power cable.
The printer comes with a USB2.0 and an RS232 data interface which can be connected one at a time
or both concurrently.
DC power connects via a 2-pin connector, details of which can be found in chapter 4.5.1
For information about the paper low input circuitry and wiring see chapter 3.5.5.
For details about the LED status indicator please refer to chapter 3.5.2.
3.4 Components and Operation
The thermal printhead (3) is positioned above the silicon platen (4). The platen acts as a roller to
advance the paper at the same time it acts as a surface against which the spring-loaded printhead
presses the paper to insure good thermal conductivity. The interface, motor used to turn the platen,
sensors, printhead, and paper cutter are all connected to the controller, which controls all these
components to function at the proper time and which also communicates to the host. The cutter (5)
separates the paper from the paper roll after printing the ticket. Several sensors monitor progress
as the printed document is created.
