I am getting a line in th fast scan direction, only on 14x17 images. It only shows up about once a day,in a very busy office, and is most often an AP chest or AP hip. It is not always the same image plate, or the same xray room. The line is always on the leading edge and always 4.2cm to 4.5cm from the leading edge. When viewed on the workstation it looks like a very thin white line, but when magnified to the max,it looks like three small lines. I have changed every part in the scan unit, but the line always comes back. Does anyone have any ideas?
