================================================== ====================
u have an external server connected ???

proper sequence to calibrate copier and imagePASS/ colorPASS

the sequence is to do an AUTO COLOR MISMATCH first, then a CORRECT SHADING, followed by a full AUTO GRADATION,
then COLOR CALIBRATION for the image/color PASS. if connected

CORRECT SHADING and COLOR CALIBRATION should be performed using a Spectrophotometer (i1 Basic Pro). if available


Also check > primary corona assembly


if all Fails__________last resort is

Backing up DC-CON: (Service Mode Level 2 Copier-Function-System-DSRAM-BUP).
Clearing DC-CON: (Service Mode Level 1 Copier -Function-Clear-DC-CON) reboot the machine.
Restoring DC-CON: (Service Mode Level 2 Copier-Function-System-DSRAM-RES) reboot the machine.
Run Auto Gradation Full Adjust.

You can't just swap devs from one machine into another on these machines. Put in a new dev and follow proper instructions(initialization,etc)
