Dear All,
I have Xerox Dc 250 machines it has a problem of color registration out.
when I start registration control setup from the maintenance and diagnostics it shows me most of value are NG.
I have done below diagnostics to solve this error but all failed.

1. tried changing registration sensor assembly (3 different sensors).
2. Initializing NVM value.
3. Re-write all original machines NVM value.
4. swapped drums and developer units from other working machine.

Please help.

try this: remove the left cover, conect tray 5, Run DC675 setup, check the marks on belt Chevrons and parallelograms shape (yellow_black marks)if one of them is NG.check for drums, developer, cleaner blade etc. Ckeck inboard, center and outboard marks.

Thank you all,
It was due to bad drums and developer assembly.
I had to change drums and adjust toner density in developer unit and run registration setup unless it comes to OK
