Abnormal TD Sensor Condition
The TD sensor output is checked every copy.
If the readings from the TD sensor become
abnormal, the machine changes the toner density
control mode to fixed supply mode 2, and the
toner supply amount per page is always 200 ms,
regardless of the value of SP 2925.
If the machine detects the TD sensor error
condition 10 times consecutively, an SC code is
generated (SC390) and the machine must be
repaired.
