<Troubleshooting Procedure>
Step
10 Open the "ATDC Sensor" screen from the
"Machine Adjust" menu of the Service
mode and check for the sensor output of
the color that is considered faulty. Is the
sensor output 8% or more?
11 When comparing the color of the devel-
oper in the Developing Unit with that of the
starter, is the developer color apparently
darker?
12 Lower the "ATDC Level Setting" of "Image Adjust" by 1 to 2%.
13 Is the I.D. of the copy made again high?
14 A. Change the ATDC Sensor and developer.
B. Make the sensor gain adjustment.
Note:
If the output image density is still high even after these procedures, change the
Developing Unit.
