4.2.2 Paper Sensor
EC-PM-80320 printer has two sensors (the light glint type) inside which are used to check whether
there is paper, and also establishes an external electric circuit to check the output of sensor. One
sensor is set under the print head, and the printer will stop printing when lack of paper is detected by
this sensor, and it is valid by default. The other sensor is located at the side of paper holder, and the
printer will stop printing when the print paper is about to use up detected by this sensor, and it is
invalid by default. The function of stop printing by the two sensors is valid or not can be set by
control program. The thermal head may be damaged and the life-span will be seriously infected due
to printing on the condition of paper out.
Table4-4 and Table4-5 is paper sensor’s parameters in common use.
