Tried this right away and it was at the highest setting even tried the lowest setting thinking maybe it was backwards and still scans the same speed. I can't think of another setting on the machine to try. I've also reached out to Graphtec but haven't heard back. I'll assume that because it's used, there won't be any service.In the ARMS menu on the machine there is a sensing speed option. might be what you're looking for...
Slow from mark to mark. Has no problem detecting the marks.slow in initial sensing of position? slow in moving from mark to mark?
or both? i am wondering if slow means a lot of retry of reading scan marks.
