How to run black paper through the 7600 hp indigo?

Keeps jamming on me, I assume sensor don't "read" paper because of the color of it. Thoughts?

 

Hi alexdasilva....all you need to do is put a 15mm white strip across grip edge...14mm wont read. Also go into diagnosis /substrate/and turn off from left to right all sensors bar feed wheel entry....far right. This is only if your printing single sided. If double you need to do same on reverse of sheet but can leave sensirs on if double sided.....i do this on a 5000 so probably the same

 

Also i use just a white crackback label stock...think its graphic vellum 80gsm
