Ricoh G104 Service Manual page 81

You can adjust 15 points for each color: (example [A]) between 0 (lowest density)
[B] and 255 (highest density) [C]. For each point, you can adjust the density within
0 and 255.
The gradation scales marked 'Default' are printed according to the default gamma
settings in the flash ROM in the controller. The gamma adjustment changes the
densities at the adjustable points in the gradation scale. The gradation scale
marked "Current" shows the current settings.
Compare the "Current" gradation scale with the 'Default' at the time you perform
the adjustment procedure. Select the density for each of the 15 adjustable points,
excluding points 0 and 255, from the 'Default' gradation scale.
The NVRAM holds three sets of controller gamma settings:
• Those saved this time: Controller SP 1101 ToneCtlSet - Tone (Current)
• Those saved in the previous adjustment: Controller SP 1101 ToneCtlSet -
Tone (Prev)
• The factory settings: Controller SP 1101 ToneCtlSet - Tone (Factory).
