WC 7120 copy calibration

[Jack79]

Hi guys

Can you help me understand calibration on this model please?

Prints are great but copies not.Magenta density is too low.
I usually performed full calibration but would like to know how to calibrate copy only as prints are fine.

Machine offers
Copy job
Print Job1
Print Job2

Target
Copy & Prints
Copy only
Print only
None

Which option should be run to calibrate copy only without affecting prints.

From my experience if I run Copy job -> copy only copy should be fine but prints will be poor after this.
Can you explain how to calibrate just copy? What is None option for? Manual does not really explain this.

What is the difference between Copy job->print only Copy job-> Copy only.

Hope someone can help.

I run calibration and of course it solved the problem and copies are great but can anyone explain what is the difference between
copy job -> copy only and copy job->print only

I would like to understand these calibration options.
Thanks
