---Problem calibrating paper on a FRONTIER 350---

I recently had to replace the RED, GREEN, and BLUE lasers. I also replaced the LDD20 board and the AD100 densitometer with another AD100. All are working perfectly.

And when trying to calibrate the paper, the colors come out very dark and dense.

I even thought it was the chemicals and I changed them (developer and bleach). There was a slight improvement, but even the first setup print comes out quite dark and yellowish. From the third attempt onwards, the yellowing apparently disappears, but the excessive density remains.
