I have received a corrupted or incomplete PDF file via Digital Hard Copy: who can I contact?
In some cases, the Digital Hard-Copy procedure may create a PDF that does not exactly conform to the original with transformation errors (e.g. loss of diagrams and/or images, or loss of text with the wrong font).
In this case you can trash the document (and forward the request back to NILDE) using the Recycle Bin button for Digital Hard Copy (screenshot) problem.
This will send an error report to the NILDE development team.
