Hello, Newbie here. Long time lurker first time posting. I finally acquired a P400 that I need to convert. I've done a ton of research on the P400 but haven't had much luck, everything seems to be about the P600. Do the rollers just lift out? or do I need to take apart the printer to get them out? If they just lift out how should they be pulled out so I don't break anything? Also how did you go about taking the sensor off the front door to use as an output tray? Do you by any chance have any pictures of what the sensor looks like or would it be self explanatory once I figure out how to take it apart? Any information would be much appreciated. Thanks.
