Hi, this post had been for many years but I think I might shared my two cents on the ARMS.
I facing the same problem on and off, sometime it would read but sometime it won't. Oh, btw I am using CE6000-60 series.
The only thing that I would do when the cutter wouldn't read my registration marks, I will find a piece of clothes and try to clean the censor. Then it will work, but 1 question is, how do we take the censor out to clean it thoroughly.
Thanks, just my 2 cents
