- if you have replaced the developing unit (Bk), reset the counter
reading.
- if you have replaced the DC controller PCB, enter the reading
indicated before the replacement.
Do not reset or change the reading of the counter unless the foregoing
is true; otherwise, the image density will likely be wrong, causing
fogging or damage to the drum by carrier. If you inadvertently reset or
changed the reading, replace the developing unit (Bk), and reset the
reading once again.
The machine's ATR control uses the patch image density measured at
specific timing and target value to correct toner supply amounts. The
target density on the other hand is also corrected for individual colors
and is corrected for Bk based on the cumulative number of images that
have been formed (monitored by the counter in question).
