Unknown Images on scanned multi page documents

Post by igorot » Tue Jul 13, 2010 8:19 pm

Hi,
I hope you can shed some light on a really strange problem that I'm encountering. We have an ADF scanner that we use for scanning vast amount of documents. I heard some complaints wherein unknown documents or possibly documents that have been scanned previously were getting added to the newly scanned documents. I verified this on limited amounts of documents and noticed that it does include and save images that were not part of the document pile in the feeder. I could not even see hard copies of these "ghost" images anywhere near me!

Any ideas?

Thanks..

Hello,

What scanner do you use? What "ghost" images do you have?

Best regards, Alexander

We have a Ricoh Afficio scanner. I call them "ghost images or pages" since they seem to come from out of nowhere. They are regular documents/images that may have been scanned previously. An unknown document/image sometimes replace a page that was fed through the ADF or randomly inserts them to the resulting multi-page file.

I think you scanner has an internal buffer and your code does not retrieve all images in the session. What code do you use?
