I have used my Epson P600 for quite some time to make digital negatives (the primary use for my printer) and in the past it has worked quite well. A couple of months ago it intermittently started only printing a partial page, leaving a blank strip on one side. Sometimes it prints the full page, other times only partial.
Any ideas what might be causing this problem? Anything I can check? I just now tried making a digital negative and three attempts resulted in three partial prints, each varying in width. I placed an image that shows these three failed prints at http://glsmyth.com/temp/105242.jpg so that you can see what I am talking about (I cancelled the third image when I saw that it was printing just one side).
Any ideas would be greatly appreciated, as I am unable to make a print that I can use.
