Auto. Adj (RU)]
Make the printer gamma offset adjustment automatically using the color density sensor attached to Relay
Unit RU-508. The gamma adjustment using a scanner includes the rising point adjustment and gray balance
adjustment for each gradation of Y, M, C, and K; however, only the rising point adjustment will be performed
when the color density sensor of Relay Unit RU-508 is used.
The adjustment using the color density sensor of Relay Unit RU-508 targets only the printer gamma correc-
tion curve formed by the internal IDC sensor.
The printer gamma correction curve formed by the color density sensor cannot be adjusted.
NOTICE
In this adjustment, the machine outputs a chart to be measured and a chart for confirmation of the adjustment
result.
NOTICE
The title number given to [Expert Adjustment] will be [04] for the machine without Image Controller IC-601,
or [05] for the machine with that option mounted.
