I have a Bizhub 250 that is giving a parallelogram-type distortion from the glass and the doc feeder - that is, the vertical is skewed, but the horizontal is straight. I can even see off the edge of the page on the one end that is skewed inward. Internal test prints are fine, so the issue is in the image reader.
There seems to be some confusion even among our "experts" whether this is a mechanical issue with the mirrors, or an image processing problem. Some say if it was the mirrors, it would skew the entire image (which makes sense to me), but others say a skewed 1st mirror would only affect the vertical. And looking at the image, it definitely looks like a pure optical skew, if only on the one axis.
