Like most mimaki owners, the retaining tabs for my media sensor on my jv-3 160s have long since departed this earth. I've been using a good ol' reliable zip tie to secure the sensor for awhile with no problems. Tonight however, my media sensor seemed to go completely haywire. I would stop and detect edges where their were none, and skip over the actual media edge. I'm using arlon 4000 for junky stickers so its not a wierd media or anything. Should I just replace it? Thoughts??
