[Misc] Xerox DC260 - Color Out Of Alignment

[manusori]

Hello everyone.

Several days ago I try to solve a problem of alignment of colors.
We have moved a Xerox DocuColor 260 to another store to work with the machine, and now the colors Yellow, Magenta and Cyan (A bit), they are not where they should be.

It had never happened to me. I tried to change the values in Maintenance / MAX Setup / "In/Out Manual Setup" introducing "Position Adjustment" the values manually, but I can not move a tenth of a millimeter colors.

I tried to remove the MOB ADC sensor and clean, but has not suffered absolutely effect.

I find no diagnostic software for the machine and Fiery CommandWorkstation not give me options to change the color values.

Has anyone had a similar problem? What else I can do to fix it?
Appreciate your help, I've already 8 days without being able to solve it.

I attached a scanned image of how the colors are displaced.

There is a software diagnostic tool but only for read/write/ save nvm's and firmware load/reload.
Complete diagnostic procedures are builtin machine service program.
Try to clean once again MOB sensor, 2nd btr roll, ibt assy belt and sensors and check if the ibt cleaner assy function properly- no streaks of toner remain on belt after ibt cleaner.
After that go into service and run color registration or much better do max setup procedure.

Make sure all colours are present in halftones, missing a colour in a particular area when it reads the registraion will result im all 0s in reg setup

Hello !


Everything I've done has failed.
What I have done to the machine has been the following:
- I dismounted (Again) the MOB sensor, I cleaned the sensors and have moved position.
- I removed the two belt (Figure 1, blue and red) and I cleaned with vacuum cleaner and brush.

- I have reviewed other media sensors and have gone over with brush and vacuum cleaner.
Many parts of the machine were like in the picture number 2.

- I have set screws that support color drums because it seems they were a little loose (Figure 3).

- Finally I printed a page for ColorCal calibration and the result is what you see. Just like before doing this.

Re: Xerox DC260 - Color Out Of Alignment

Did you print test pattern 11 on all colours to see if there were any really bad fade out on inboard or outboard side?? Its usually because it cant read a colour, also you can remove plastic panel where tray 5 sits and look at the arrows when it runs its reg setup, make sure all is present, also there is a metal shutter on the mob sensor that you can remove, failing that itll could be the ibt assy or mcu, but try the halftones first

Hi again, everybody.


Mickey, I printed two patterns (11 and 1) before and after removing the blind MOB sensor.
I have to say that the clear strip that comes right out of print, is produced by the magenta drum, before the transfer of the store the drum mades the strip and we have to change the drum. But before the transfer of store colors were aligned.

The result I get is practically the same.
Now the MOB sensor has not blind:

Did you print test pattern 11 in single colour also?

Re: Xerox DC260 - Color Out Of Alignment

Yes, I've tried in yellow with Cin. 60% and Xerox prints full page in yellow a bit displaced.

I can't scan now, but tomorrow I'll do.

Try all colours at 26% it will show more

Re: Xerox DC260 - Color Out Of Alignment

Hello everyone!


I have scanned the result of pattern printing 11 yellow 60% and all the colors to 26%.

There is a drum arcing in the 2nd pic, fix that and run reg setup and it will work

Hello partners.

I fear that not just any drum. Before misalign the colors, the drums were already like that. The magenta drum showed that deficiency and had to change it, but when moving the machine misaligned all colors.

I think the drum having a slit is magenta, but the magenta drum comes after the Cyan, and cyan drum is already misaligned.

I tried to clean the sensors ROS, but I keep getting the same results. Referring to the manual, this tells me two units completely change: MCU PCB and PCB ESS. But it seems exaggerated.

I post the last scans:
