Hy everyone. Sorry if my english is not so good;). I have a problem with a minolta di 620.
First the copier gives me all kind of errors, such as c0400, c1038, c1039 . I have changed the PWB-B and all the problems were resolved, until a try to make a copy. the problem is that when i scan from EDH (RADF) the copy is clean and ok. but when i scan normally, a shaddow appears on copy. I have tried to clean the lens, mirrors, the CCd sensor but still no results. I attach a picture with the original and a picture with the copy :

Is this copier sitting next to a window?

You can do a simple test, maybe you already did this ... anyway, put on the Original Sheet... 5 or 10 Paper Sheet A3 or 11x17 normal white.

Check.... if this well, you should adjust the closure of EDH, this can be closed incorrectly allowing the original release, also check that the Original Glass Assy is properly mounted.

finally can check the guide on the scanner is transported, and what it says RRogers also is a good point.

It looks like light is getting under the EDH. Make sure the EDH closes properly (all four corners sitting flat)
Hope this helps

I did the test with the A3 paper, still no result. i have put a shet on glass and then i cover all the glass with big black paper, then i closed the EDH - no result. i have changed the glass, also no result.
is there an auto calibration of scanner or something like that? I have run from Tech. Rep. the Exposure lamp check. the result was "Good". I don't know what to do next... I'm thinking to find a scanner to replace and i hope i will resolve my problem. until then, if you think of something that i could try i will be happy to do it :) THANK YOU VERY MUCH FOR TRYING TO HELP ME

Ok if you completely change the scanner will notice immediately, do not forget to check that the scanner is receiving any reflection from the outside.

Parts to review: if you do not know these parts check the Parts manual so you can identify them.

The following must be square.

In Scanner section: Slider, Shaft, Slider Plate assy, Mirrors: (Holder)

I have manage to make the copier to work. I did not replace any part of the scanner. I have simply spread the cable that moves the scaner, and readjust scaner pozition. But my problem now, is that i can not make all the adjusments of the edh. I dont know were or how can i print the edh test chart (This is what i need as the service manual tell me). So if you know this, i appreciate the help.
