Scanner lamp stays on
The scanner lamp turns off after each scan. After about 15 minutes of inactivity, the

30 seconds, and then turn the scanner back on.
Scanner does not scan right away

If the scanner is in sleep mode, press the Power button to wake the scanner up.

option has been selected.

Optimize scanning and task speeds
Several settings influence the total time for a scanning job. When you want to optimize
scanning performance, consider the following information.

To optimize performance, make sure your computer meets the recommended
system requirements. To view minimum and recommended system requirements,
, select your country/region, search on your scanner model, and
then search on datasheet.
y
In the scanning software, choose the layout setting that matches the orientation of
the originals in the document feeder.

If you are scanning to editable text, the optical character recognition (OCR) software
requires more processing time than for non-OCR scans, which is normal. Wait for
the item to scan.
