surface reflection rate abnormality)
Usually the sensor gain is adjusted so
that the output is a certain value, by
reading the drum base surface with the
image density sensor before starting
process control.
However, a certain output is not
obtained by adjusting the sensor gain.
Image density sensor defective
Check process control sensor output
with SIM44-2. (Do not adjust)
If the result is far different from the
specified value, it suggests the sensor is
defective. Check the sensor and harness.
If the deviation is relatively small, check
the sensor and drum surface for
contamination.
