Content Process control trouble (drum marking
sensor defective)
Detail
Usually the sensor gain is adjusted so
that the output is a certain value, by
reading the drum base surface with the
drum marking sensor before starting
process control.
However, a certain output is not obtained
by adjusting the sensor gain.
