2-2. Operation of Control Parts
2-23
CLP-621 & CLP-631
Reflective sensor (used for detecting the black mark on tag):
When tag with black marks is used, light is reflected by the tag. In the place where no
black mark is there, the phototransistor of the reflective sensor conducts and the voltage
corresponding to the amount of light is applied to pin 6 (ANI1) of IC1 (CPU). When the light
falls on the black mark, no light is reflected. In this case, the lower phototransistor turns
OFF and pin 6 of IC1 (CPU) will go “Low” level.
When media runs out, the light is not reflected and no light falls on the reflective sensor. In
this case, pin 6 of the CPU will go “Low” level and media end is detected.
As to the current control of the LEDs, the operation is the same as for the transparent
sensor.

Caution:

DO NOT adjust VR1 and VR2 on the Main PCB. (Leave them at the factory setting
condition.) If it is changed, media sensor sensitivity is changed and the media
detection will not be correctly made.
