We have an OCE TDS400 and are having problems with it shrinking AutoCAD drawings. It seems the longer the line the more it is off. It's not alot, maybe 6" on a 50' line at 1/8" scale, but what's the purpose of drawing things to scale when they won't print to scale. We had an OCE tech come in and he said the machine was calibrated fine so it must be a software issue. We are using ADT3.3 but we can't find anything wrong. Anyone else have this problem? Thanks,
