SC350: ID Sensor Error 1
Definition [D]
One of the following ID sensor output voltages was detected when checking the ID
sensor pattern.
• Vsp ≥ 2.5 V
• Vsp = 0 V
NOTE: 1) Vsp is the ID sensor output after checking the ID sensor pattern image.
2) The SC code is not displayed; only the logging data is incremented.
3) Regarding toner supply, if an abnormal condition is detected, then only
the toner density sensor output is used, without an updated Vref
setting.
4) After an abnormal condition is detected, SP3103 (ID Sensor Output
Display) shows Vsp = Vsg (or 5.0V).
Possible Causes
