I have a 2520 color unit that makes perfect prints/ internal prints. But has blurry dirty copies from the glass and doc feeder. In fact the copies are worse going thru feeder than the glass andbody have any ideas???

First do the Auto Gray Adjust (or sim 410) and try that. Make sure to do the color registration and calibration prior to this.

Try a scan and see what the image looks like on a computer screen. Could be as simple as dirty optics.

Dirty optics was my guess also but we have cleaned everything but the casters. I would think that color calibration would also effect the internal prints also?? am I right there??

You are right, but that should be done prior to running the Auto Gray Adjust (that is the user function where the 2 color patterns are printed which you place on the glass to scan). Gray Adjust affects copy and scan more.

I pretty much do Color Registration, Color Calibration, and Auto Gray Adjust on each and every service call for color copiers I run. Even more important to do following a firmware upgrade.

ya we have done the firmware upgrade, and all the adjustments as well. Crazy

IF it has to do with the scanner system, try doing a color scan to a computer file or Email, is the problem visible on the scanned file? If your not sure, print the scanned file to another printer, or save to a thumb drive and print it on another priter back at your office. If the problem is seen in the scanned file your problem is in the scanner.
