It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate Template:PD-old tag instead. For usage, see Commons:When to use the PD-scan tag. Note: This tag applies to scans and photocopies only.
