Hi. I have an Epson XP352 and no matter what I do with the rear document feeder, all sheets do not go through dead perpendicular - when the printer 'grabs' each sheet, it becomes slightly skewed (I ensure that the guide is pushed up against the edge of the paper). Ok when your printing a letter but a nightmare when you do labels of course as by the end of the sheet they are off the edges of each label. Any ideas of what I could do guys?
