Aficio 1022 - sprawdzanie sprawności ID sensora

Jak sprawdzić czy jest sprawny ID sensor ???

na początek proponuje lekture kawałka dokumentacji


ID sensor
Readings are abnormal if any of the following conditions occur:
• Vsg ≤ 2.5V
• Vsg < 3.5V when maximum power (254) is applied
• Vsp ≥ 2.5V
• (Vsg – Vsp) < 1.0V
• ID sensor power required to make the standard output reaches the maximum
value (254)
The above ID sensor values can be checked using SP2-220.
When this is detected, the machine changes the value of Vref to the previous value
then does the toner density control process (in a similar way to sensor control
mode 2).
No SC code is generated if the ID sensor is defective.
