7.4.6 Laser Output Corrective Control
0010-8044
iR7105 / iR7095 / iR7086
If the optimum laser output cannot be determined after measuring the drum surface potential, the machine starts its compensatory control sequence to determine
the optimum laser output.

7.4.7 Determining the Optimum Developing Bias
0010-8045
iR7105 / iR7095 / iR7086
The machine uses the optimum drum surface potential (VD) to compute the optimum developing bias (Vdc).

Continues to take measurements while varying
the laser output so that it will approach
Target VL
Compensatory control sequence started
If the measurement is identical to the target VL, ends
control; executes measurement a maximum of 8 times,
possibly using an approximate value of the target VL.
Determines a laser output needed
to attain the target VL.
