of IC1 becomes a low level. / Then when it becomes a high level, it
triggers point (A). / In point (C), according to the voltage output
time, the thermal head's temperature is detected.
After the thermal head temperature is converted to voltage in (B),
it is then changed to digital data in the A/D converter inside IC1.
The CPU decides the strobe width of the thermal head according
to this value. Therefore, this circuit can keep the thermal head at
an even temperature in order to stabilize the printing density and
prevent the head from being overheated.
5.3.8. LED ARRAY(CIS)
The LED ARRAY will light during transmission and copying as a light source to recognize
document characters, patterns, or graphics on a document. / It is also possible to light the LED
ARRAY in the test mode.
