Ricoh Gestetner LANIER SAVIN G071 Service Manual page 107

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.
During the adjustment procedure, compare the "Current" gradation scale with the
'Default'. 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: ToneCtlSet - Tone (Current)
• Those saved in the previous adjustment: ToneCtlSet - Tone (Prev)
• The factory settings: ToneCtlSet - Tone (Factory).
