2.7.3 Adjusting Sensors
This function is provided for adjusting printer’s sensors (Reflective, Transmissive, Strip, and No paper level).
The sensors have been optimally adjusted before shipment from the factory. Therefore, the sensors should
not be adjusted, except when there is a need to adjust them. If the sensors are adjusted, be sure to follow the
procedure described below, or the printer will not operate properly. The interface to be used for adjusting
sensors, should be “IrDA: TEC Protocol”.
* “IrDA: IrCOMM” is not supported for the sensor adjustments. If the sensors have to be adjusted when the
destination “Other countries” has already been registered, set “F1: Transmission Control” and “F2: Destina-
tion” to “IrDA: IrCOMM” and “Japan”, respectively and register them. Then, adjust the sensors.
When using the keyboard, press the [F1] or [F2] key together with the [Ctrl] key.
* To increase efficiency, until when the printer is turned OFF from when reading the sensor A/D values and
each sensor adjustment are performed, a feed is not performed when the cover is closed.
1) Reading sensor A/D values
Connect the IrDA jig (Actisys IR) to the serial port on a PC, then start up the software for production
process.
Turn the printer ON, then face the IrDA jig to the upper IrDA windows of the printer.
Press the [F3] key of the keyboard or click on the [F3: All sensors] button on the screen.
All of the current sensor A/D values will be read at once and displayed.
