Abnormal ID Sensor Conditions
ID sensor readings are abnormal if any of the following
conditions occur:
Vsg ≤ 2.5V
Vsg < 3.5V when maximum power (979) is applied
Vsp ≥ 2.5V
(Vsg – Vsp) < 1.0V
Vt ≥ 4.5V or Vt ≤ 0.2V
The above ID sensor values can be checked using SP 2221.
When this is detected, the machine changes the value of Vref
to 2.5 V 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.
