Lines In The Scanned Image Appear Too Thin Or Discontinuous - HP Designjet T11 MFP Série Guide De Référence Rapide

When power, wait, diagnostics, and paper-ready lights are all flashing, it means the
scanner has powered up in Boot mode. This mode is used in emergency cases to
upgrade the scanner's firmware when the upgrade-firmware process has been
interrupted. If the scanner shows this combination of flashing lights, try the following
remedies:
●
Reboot the scanner and the touch screen.
●
If the scanner remains in Boot mode, perform a system recovery with the
System Recovery DVD that came with your scanner.
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
settings on page
