DC 2060 fusing problem

[kandod]

Hi all, I have this problem with Xerox Docucolor 2060 for a long time already, image not fused evenly in centre-to-INBOARD and OUTBOARD direction, and the result is some colour shift along the edges plus the toner surface having more matte look inboard and outboard compared to the centre. Changed the fuser pad kit, belt and heat roll, and tried with different nip settings, the only way to have better prints is to tighten the nip adjusting screws to their max (thus maximizing the nip). Any help appreciated!

Check the oil system. This may happening if you have too much oil on fusing roll.
Check the oil drain from oil system to oil container.

The oil looks normal. What I noticed however, were the two red screws that sit just in front of the fuser nip adjustment screws (hidden under the belt finger assy plate) and as far as I see they are to regulate the force the fuser pad kit presses into the heat roll and it looks logical to have something to do with my problem. From my experiеnce with docucolors I now that the red screws are not to be touched, so if anyone knows what exactly these are for please tell me if it is safe to make adjustments.

there is a spacer kit that you use to adjust that
I think the gat is 5 or 5.5 cm

Here is the Nip Adj Procedure 10.1
Enter DC701 Fuser Nip Measurement.
Select a tray with either 8.5x11 (A4) or 11x17 (A3) 24lb (90gsm) paper.
NOTE:
For best results use Xerox Color Xpressions paper.
Select Start.
NOTE:
The print comes out upside down. Ensure that you mark the black side of the print Inboard and Outboard.
Remove the print and mark the Inboard and Outboard side of the print.
NOTE:
The Fuser Nip is located about the center of the print on the black side.
Select DC612Color Test Pattern Print. Select Pattern 7 Color Reg. Run three prints.
Perform DC701 Fuser Nip Measurement two more times after waiting at least 30 seconds between each run and perform DC612 Pattern 7 Color Reg. between each nip check.
NOTE:
Steps 5 and 6 are performed to stabilize the Fuser.
On the last of the Fuser Nip Prints, measure 10mm in from the edge of the sheet at the Fuser Nip on the Inboard and Outboard side of each of the prints.
The Fuser Nip specification is:
4.1mm ± 0.2mm Inboard
4.2mm ± 0.2mm Outboard
Adjust
Pull out the Transport Drawer to the service position.
Open the Inverter Transport.
Open the Fuser Exit Chute Assembly.
Adjust the screw(s) located through the hole in the P/R Finger Bracket:
To increase the nip, turn both screws CW.
To decrease the nip, turn both screws CCW.
one full turn equals .5mm.
