C352 Test Pattern Error when performing Gradation

[Haroldbfix]

The Optics, Lens & CCD are clean. The Gradation sheets are allign correctly with 10-15 white sheet covering the glass. The gradation sheets look great. I've done the adjustment many times on many machines with now problems until today.

Any Ideas out there?

What error is it giving you?

I wouldn't think twice.I have it at my copy shop and its a little nasty when firmware comes in question.Rewrite it as soon as possible. If u don't have it we will send it to u becose its a great machine and we wouldn't like to hear different opinion :)

"Test Pattern Scann Error" or something close to that.

I do have firmware I will try that.

I Have Seen This A Couple Of Times. Usally It Is The Firmware That Does It. I Have Also Had A Problem With One And I Believe I Had To Change Something In Techrep Mode But It Was New Out Of The Box When I Had To Do That

I have also this problem and after some tests the problem was in the paper cassette that it's broken

I have also seen this problem, the 1st time it was a brand new out of the box machine and it turned out that the second mirror was chipped on the backside in the image area, I flipped the mirror and got it out of the image area and it worked fine. The last time I saw this someone had put a large amount of pressure on the front left corner of the machine and had bent the whole scanner down slightly, I did a "power lift readjustment" to that side of the scanner and low and behold it got rid of the error. I also found a mirror out of place causing the same deal on another machine that had been shipped out of the box.......... I mean this thing was barely out of whack and I got the test pattern error. If all else fails do the gradation on letter size paper!

make sure ur test pattern is put on the mirror corrrectly.sometimes it's cannot read when u put it wrongly.
