How to adjust fuser unit temperature on Konica Minolta 225i?

Konica Minolta 225i always prints with black dots, which are easily removed by hand. The toner seller tells you to change the toner, and the parts seller tells you to replace the fuser, but they never tell you to increase the fuser unit temperature. Actually, increasing the fuser unit temperature would solve the problem.
