Basically the problem is in the blue print,
small white dots appear. If anyone knows about it, I am grateful.

I've had good luck with that by lowering the transfer voltage. I cannot remember if it was primary or secondary transfer, secondary I think.
A little trial and error with that and you should be good.
Good luck

I am guessing old/bad developer. Try a new cyan imaging unit IU610C part number: A0600JF.
First thing is I would go into service mode and run some color sample pages.

try an alternative reputable brand of paper before anything else.
If your using the cheapest paper you can find and expecting perfect print quality - go away.
