350 C ID sensor pattern test error
One of the following ID sensor output
voltages was detected twice
consecutively when checking the ID
sensor pattern.
1) Vsp ≥ 2.5V
2) Vsg ≤ 2.5V
3) Vsp = 0V
4) Vsg = 0V
351 C ID sensor Vsg test error
When the ID sensor was checked, the
ID sensor output voltage was 5.0V
while the PWM signal input to the ID
sensor was 0.
352 C ID sensor, pattern edge detect error
The ID sensor pattern edge voltage is
detected to be not 2.5V twice
consecutively during an 800 ms
interval.
353 C ID sensor, LED current abnormal at
initialization
One of the following ID sensor output
voltages is detected at ID sensor
initialization.
1) Vsg < 4.0V when the maximum
PWM input (255) is applied to
the ID sensor.
2) Vsg ≥ 4.0V when the minimum
PWM input (0) is applied to the
ID sensor.
354 C ID sensor timeout abnormal at
adjustment
Vsg falls out of the adjustment target
(4.0 ± 0.2V) at the start of Vsg checking
after 20 seconds
