Manuals for C6500

Does anyone have or do they even exist manuals for the Konica C6500 that tells you about color and quality adjustments in detail. Like in the service mode- what all the screen and adjustments mean- for instance- under the "process fine adjustment" menu what all the options mean and what they do. Like the gamma adjustment and develop Ac frequency.
Trying to improve quality but don't want to randomly start adjusting things.

Thanks
