I know it has been a long while since this post, but did you ever find a solution?
Hi! I have a jaguar IV too, and when i turn it up, it sizes de the media and everything is fine... I send a job to cut and it gives the sensor/carriage error... I turn it off, re-start send the job, and it cuts great... I always have to re-start the machine... Can you help me? Witch settings do you change? And Witch lens és do you clean? Thank youThanks for reply. Sounds like a frustrating experience, glad it's all good in the end. have to say luckily our machine, started to work fine after i cleaned the lenses and the rails from dust. and who knows maybe because I changed some settings on my computer. But it's working for now, hopefully it stays that way , and isn't anything more serious, like in your case. Thanks best
