351
C
ID sensor error 2
The ID sensor output voltage is 5.0V
and the PWM signal input to the ID
sensor is 0 when checking the ID
sensor pattern.
352
C
ID sensor error 3
For 2 s during the ID sensor pattern
check, the ID sensor pattern edge
voltage is not 2.5V or the pattern edge
is not detected within 800 ms.
353
C
ID sensor error 4
One of the following ID sensor output
voltages is detected at ID sensor
initialization.
• Vsg < 4.0V when the maximum
PWM input (255) is applied to the ID
sensor.
• Vsg ≥ 4.0V when the minimum
PWM input (0) is applied to the ID
sensor.
354
C
ID sensor error 5
Vsg falls out of the adjustment target
(4.0 ± 0.2V) during Vsg checking.
355
C
ID sensor error 6
The Vp value, which measures the
reflectivity of the ID sensor pattern,
was not in the range of –70V to –400V.
