Xerox WorkCentre 7665 Fails Copy and Print Calibration

[chorton]

We have a Xerox WorkCentre 7665 that works fine, prints fine, but when we try to calibrate copy or print it always fails. It prints the calibration pages then I feed them into the document feeder and it scans the pages then says calibration failed. Is there something specific I need to do to make it work again?

Thanks,

you don't feed them thru the doc feeder.. you put them on the glass

The original poster is correct, you do feed them through the doc feeder.

I'm pretty certain he's talking about the Xerox/WorkCentre PRINT calibration, and there are two sheets, not a Fiery ColorCal calibration, or the COPY calibration. It is impossible to do the print calibration manually on the glass.

As to the original question, I fight this often, and have found three primary causes...

One, the easy one, is to take off the glass and carefully clean the mirrors and the scanner lens. I have many times had this clear up a "Calibration Failed" situation.

The second, is if your black is not printing well. See the two black squares at the top left corner of all the patches? They are in different positions on the two sheets. (That is how the software detects which is sheet one and which is sheet two.) If those are washed out at all, calibration is likely to fail.

If everything seems to be printing pretty decently, you just want to get your colors balanced, but it is failing because those black patches are slightly faded, you can color them in with a Sharpie before you scan it... haha That almost always works for me. (Don't do it to any of the ACTUAL black color patches, or you'll skew your calibration.)

The third failure, which I've not found a way around, is if you are using generic toner. Somehow, the densities can be out of range of what it expects just enough for it to fail, even though it may look okay to the eye. I suspect on a DocuColor machine with a Fiery where you can use a ES-1000 spectrophotometer to scan your patches, it could probably overcome this. But the "rudimentary" WorkCentre's built in calibration can't. There is no workaround for this one.

Hope yours is #1 or #2! haha Good luck.

Correct I'm talking about the Xerox/WorkCentre PRINT calibration. Thank you for the suggestions, I will try those out and let you know.

just had the same problem on a 7530. found that the DADF registration was off. corrected that and it calibrated fine.
