Interesting issue now it seems as though the solonoids are reversed in mode u243 when i run the "rev prs sol" which i imagine means pressure solonoid, the switchback solonoid operates (the lower and smaller of the two. Am i reading the manual wrong? They cant be plugged in wrong because they are 2 and 3 pin connectors respectivly. When i run "rev brch sol" the higher and larger of the two solonoids operates. Just a refresher the df cuts the second side of a 2-2 image off because it shits the image toward he lead edge about 4 inches, no jams, off the glass and 1-2 duplex fine. Updated firmware for kicks, all spring and rollers look good.
