They are in the printer.

I'm wondering what point there is to them if they are not used, usually?

I mean why add complicated adjustment procedures if only a few people will  
ever tinker with them?
To give the service center something to charge for?
Why explain the procedures in the service manual and why make a software  
to support the whole mechanism?

It is like adding trimmer pots to a circuit only to have them all set to  
mid-scale ;-)
