I've got a large order for 102" signs that we are running on Sihl 3333 paper. Now the 950 usually walks a little on roll feed media but this stuff can barely make it through a couple prints before it's climbing off the edge. The print is 35" wide, we had to go to the 42" paper size and it's still only able to go 3-4 prints before I have to stop it and reload the media. Anybody else run into this? Any tips? The 950 has been a huge step up for us and have been very satisfied with it but this little glitch is slowing this tightly scheduled job down. I am assuming the main issue is with this particular paper.
