Screen DT-R2035

[elmartin4]

I have a Screen DT-R2035 imagesetter with online processor. Imagesetter was working normally for a long time.
But now an error E31141 or E21141 apears when I trying execute FEEDING command.
Looking for E21141 in manual user i found: "The material has clogged between he cutter and the recording drum. I checked between cutter and drum but there is not any material in this area. I turned off and on the imagesetter and machine turns READY. But if I try to FEEDING error appears again.
Somebody help me !!!!
