Again instead of just shouting out faults, do a little research before telling someone to do this and that. I've had a look at the servicemanual ( found here
) and according to the light it could either be a faulty consumable and/or a paper stuck in the paperpath.
Have a look under all covers, make sure no papers are stuck.
Look at the service manual, see if any sensors are perhaps stuck/damaged/dirt on them.
If problem still persists, contact samsungs supportline and see if they can help you, or get a quote on how to get it fixed.
