Question

Why are my scanned documents so large?

Laserfiche Scanning

Laserfiche 9.1

I can scan a color duplex document on our MFP (most recent document was 158 pages) and it only ends up being 5.96 MB in size. I scan that same document in color, duplex with LF Scanning and the document is 198.33 MB!!!!!!!! This makes a document WAAAAAY to large to email. This has become a huge issue when scanning approved legal invoices and some claim files. Sometimes I can scan a color/duplex invoice that is only 10 pages and it becomes to large to send via email. I don't understand this and can't figure out how to fix it. Not only that but after I scanned the referenced 158 page document on our MFP and tried to import it into LF it took 15 minutes. I scanned the document directly to LF and, though the size was 198.33 MB, the import only took seconds. Not being able to email a document after it is scanned kind of defeats the purpose of us using LF to scan or even house documents. I am having to use our internal MFP scanner and store on my computer in order to send certain documents. Is there a known fix for this issue?

The DPI is a scanner setting, not a Laserfiche setting. You should be able to access it from the scanner toolbar in Laserfiche Scanning. It cannot be changed after the fact.

Laserfiche defaults color images to TIFF LZW which provides better image quality at the expense of the file size. It can be changed to JPG which loses a bit of image quality (mostly negligible) but produces a smaller image. See this KB article on how to set it.

Miruna, is there a way to set this in the Admin console as a global setting for all users? If not is there an easy way to set this through the user interface? Configuring this setting via trustee attribute is not the easiest way to handle this.

Yes, you can set it on the Everyone group and it will be inherited.

Just to be clear...the 1st screenshot is of the file when scanned by our MFP and saved to my computer. The 2nd is of the file size after being scanned directly by LF Scanning. Thanks.

its probably because you are scanning in color and at a high DPI. Try setting your MFP to do 300dpi in black and white.

Hi Robyn,

This has everything to do with file formats. When scanning from your MFP, it will scan in PDF which is a compressed file format. When scanning in LF Scanning you are scanning in TIFF/TIF format which is uncompressed. A colour page in TIFF at 300 dpi can be anything from 10-20MB in size so you can imagine a multi page document getting very big very quickly. The best option when scanning in colour is to scan in PDF format from a network MFP. If that isn't an option, you can set the DPI in LF scanning right down to 50dpi and not see any notable difference on quality.

Hope this helps explain!

Chris,

That is exactly what I thought and hoped there was a solution. Where do I go within LF to change the DPI? I can't find it in 9.1. So there no way to scan to PDF in LF that maybe I just don't know about?

Tommy - It is not my MFP that I am trying to fix it is the LF Scanning. Our MFP scans are exactly the way we need them to be but we cannot utilize the LF scanning features if we use it that way.

Thank you both for your replies!! Very helpful.
