You can use mail merge fields in an UNICOM Intelligence Interviewer - Paper/Scan Add‑on document; for example, to insert names and addresses from a mail merge file or database. However, for questionnaires that you are going to scan, it is important that the positions of the mark and character fields do not change. Merging the document changes the positions of these fields if information inserted into a merge field requires more or less space than the merge field itself. However, you can prevent the positions of the mark and character fields from changing by putting the mail merge fields in a text box of a predefined size.
