xerox docucolor 250 custom profile and separation questions

Hi, I'm trying to make xerox laser printer/copier docucolor ICC profile.
I have CMYK TIF test chart file with patches. How to correctly print the file.
I mean are there printer specific settings that need to be set.

I know when printing testcharts the colormanagement should be turned off. How can I do this on docucolor 250?

What separation settings are best for it?

The standart color laser:

Separation MAXK
Black start 5
Black Max 100
CMYK Max 400

Black Point C100 M100 Y100 K100
Black width 100

found these values for docucolor somewhere:

Separation GCR2
Black start 0
Black Max 100
CMYK Max 260

Black Point C40 M60 Y60 K100
Black width 100

I would be thank full for simple separation parameter explanation.

 

Probably need to ask that one at http://fieryforums.efi.com/forumdisplay.php?f=127
