Hi all.
First of all - hi to everyone. I've been reading the forum for a while, as I'm pretty new to the business (bought my Graphtec just a year ago) mainly treating it as hobby with plans to advertise to the public. For last year had many ups and downs with my machine, learning from own mistakes and searching solutions online. Asking on forum is usually a last resort for me and that time has come.
But to the point

:
I recently ordered my first flex vinyls from MDP Supplies in UK in order to make some T-Shirts.
Everything went fine until I wanted to use black roll of flex.
Every time I feed the roll, the plotter "scans" the roll and moves the blade to the starting point (bottom right) - no problems, recognizes the media etc.
When I send the job it starts and suddenly stops and "NO MEDIA" message appears. It happens at the point when sensor is exposed (vinyl not covering it for a split second) - but that doesn't happen with other colors despite the same procedure).
It's really weird, because I tried different flex colours, sticker vinyls and it finishes the job without any isssues!
Any ideas how to solve that or what can be causing it?
I can record a short clip and post it tomorrow if that will help.
Thanks in advance for reading and your help.
Kind regards
