Lines in the scanned image appear too thin or
discontinuous
When scanning documents with thin lines such as CAD drawings, a scan resolution
setting of less than 300 dpi can result in disproportionately thin or discontinuous
lines. HP recommends that you set the scan resolution to a minimum of 300 dpi
when scanning CAD drawings and other documents with thin lines. Scanning with
higher resolution lengthens the overall scan time, but it ensures greater image
quality. This issue is not as noticeable when scanning photos and area fills. For
more information on setting the scan resolution, see
Set the output quality
on page 17.
The images below help to illustrate the issue:
