During a print run the color tends to shift. I haven't seen any patches that address this issue, and it appears to only occur during a print run, the engine seems fine. Wondering if anyone else has had issues with this fiery server, or if the system software might need to be re installed. Any thoughts or sugesstions would be greatly appreciated. I've addressed the engine and cleaned all the lasers, and performed all the autograd and calibrations.

Re: image pass B2
Sorry, the entire output has a gradual shift in colour, from the first print of a set compared to the later outputs, same file, long run. The customer has been doing the autograds and calibrations, as I had also after cleaning the lasers for lines. The prints themselves look fine, side to side, front and back, however there is a difference from the first to last print, although each print itself is even throughout itself. Hope this clarifies, thanks!Comment

Re: image pass B2
So you mean color gradation / saturation starts off OK!!> then is not constant throughout the finish run
how do u calibrate the B2 ????
Color quality is not consistent
File or application problem--
1. Print a different color test page from another application.
2. If the quality of the test page is good, there may be a file or application problem.Out of calibration or calibration information/ curves on the active
partition are corrupted--
1. If you suspect that a custom calibration setting is causing the problem, reset the calibration setting to its default measurements:
In Command WorkStation > Device Center > General > Tools, click Manage.
Calibrator opens.
In Calibrator, select the calibration setting that you suspect is causing the problem, and then click View Measurements.
Click Reset to Default Measurements, and then click Yes to confirm.
If resetting to default calibration does not solve the problem, you may need to service the copier.
2. If restoring default measurements fixes the color quality, the custom calibration may have been the cause of the problem. Request that the site
administrator recalibrate the imagePASS. For details, see Color Printing,
which is part of the user documentation set.
3. If the problem persists after recalibration, the calibration information on the hard disk drive may be corrupt. Reinstall system software.
4. If the problem persists, the hard disk drive may be corrupt. Verify that all hard disk drive cabling is correct.
5. If hard disk drive cabling is correct, you may need to replace the hard disk drive.
Spot Color Matching
When Spot Color Matching is set to On, banding (visible steps between the shades in a color gradient) or bands of color that are missing altogether might result in the printed image. Also,
if you print separations, pages might be printed in color, instead of black and white. These undesirable effects depend on the application. As a workaround, set Spot Color Matching
to Off.
Resolution print option
When Adobe Illustrator pattern tiles are applied to a large area of a job's object, a part of the object might not print correctly with Resolution set to 1200dpi. In this case, set Resolution to
600dpi.

Re: image pass B2
Went over all the chips and pcbs, reseated and cleaned the image pass out, and reloaded system software a week ago. The customer hasn't called back, seems as though this was the fix for this issue, thanks for your help!Comment

Re: image pass B2
Clean the patch sensors. They are used for setting color registration along with reading density. Make sure the shutter isn't broken. Very common. Usually if color registration is wandering or colors are poor/changing.. the patch sensors are dirtyComment
