HP ScanJet Pro 4500 fn1 - Manual (Page 58)

Scan files are too large
● Most scanning software allows a smaller file size to be selected when selecting the output file type. For
more information, see the Help for the scanning software being used.
● Verify the scan resolution setting (for more information, see the Help for the scanning software being
using):
— 200 dpi is sufficient for storing documents as images.
— For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable
text.
— For Asian fonts and small fonts, choosing a higher resolution is recommended.
NOTE: For some special black dot background scans, saving the image as a .tif file might make the
image smaller.
Scanning at a higher resolution than necessary creates a larger file with no additional benefit.
● Color scans create larger files than do black and white scans.
● If scanning a large number of pages at one time, consider scanning fewer pages at a time to create
more, smaller files.
Issues with text recognition (OCR)
Issues with text recognition (OCR) (Windows)
The scanner uses optical character recognition (OCR) to convert text on a page to text that can be edited on a
computer.
● If text can be scanned but cannot be edited, make the following selections before scanning:
— Select a scan shortcut that supports OCR. The following scan shortcuts support OCR:
○ Save as PDF
○ Email as PDF
○ Save as Editable Text (OCR)
○ Send to Cloud
○ Everyday Scan
— Select one of the following OCR-based, output-file types from the File Type drop-down box:
○ Text (.txt)
○ Rich Text (.rtf)
NOTE: If an OCR-based, output-file type is not selected, the document is scanned as a graphic and the text
is not editable.
● Check the originals
