Ok so I'm using the machine for the first time in a few years and I wanted to make sure it was working ok and decided to put in a board and just see if it could read the measurements. It seems to start ok but after a little while it stalls on one spot and keeps moving the board back and forth like 1/4" at a time faster and faster. Occassionally it gives up and displays a Check Tracking Roller message. I looked it up and I think I went through the possible solutions ok. Wiped the rollers, blew air at sides of the rollers where the washers are, made sure board was over 1/2" but still no joy. Ugh, I think I remember why I put it in storage for so long.
