Conditions
SC360-01
D
TD sensor adjustment error: Adjustment output abnormal
During the TD sensor auto adjustment, the TD sensor output voltage
(Vt) is 2.5 volts or higher even though the control voltage is set to the
minimum value (PWM = 0). When this error occurs, SP2-906-1 reads
0.00V.
Note: This SC is released only after correct adjustment of the TD
sensor has been achieved. Switching the machine off and on will
cancel the SC display, but does not release ID sensor toner supply.
-
 TD sensor defective
 TD sensor harness disconnected
 TD sensor connector disconnected or defective
 IOB defective
 Toner bottle motor defective
Note: When the TD sensor is defective, the toner supply is
controlled using pixel count and the ID sensor.
SC360-11
D
TD sensor adjustment error: Timeout Error
During the TD sensor auto adjustment, the TD sensor output
voltage (Vt) does not enter the target range (3.0 ± 0.1V) within 20
s. When this error occurs, the display of SP2-906-1 reads 0.00V.
Note:
This SC is released only after correct adjustment of the TD sensor
has been achieved. Switching the machine off and on will cancel
the SC display, but does not release ID sensor toner supply.
