There are many potential issues in your workpiece that could be causing this error message. However, each issue is an easy check and an easy fix. Check to make sure that all the following are true of your workpiece:
1) Any ‘tape jig’ or workpiece that has tape on it is firmly secured, preferably with both double-sided tape and a clamp. Even very small shifts in tape or material location that may not be visible to the human eye could compromise cut accuracy or integrity.
2) All your tape is coplanar. If you have tape on multiple pieces or jigs, make sure that they measure the same height from your worksurface.
3) There is no tape that is only partially adhered or 'dangling' off the edge of a workpiece.
4) You have no waste tape that is not a part of your workpiece, ie, tape that you have removed and put aside but that may still show up in Origin's field of vision.
5) All your tape is smoothly adhered to your workpiece, without any wrinkles or bubbles.
