<p>[QUOTE=&quot;krispy, post: 1396008, member: 19065&quot;]I&#039;ve never really seen a &quot;computer&quot; scanner, though I have seen and worked with quite a few different models of &#039;document&#039; scanners that are connected to computers and used to capture digital image files of physically flat objects.</p><p><br /></p><p>Now, you may have &#039;looked around&#039; already, but you certainly didn&#039;t look hard enough because it hardly takes much looking to find a bevy of &quot;<a href="http://lmgtfy.com/?q=portable+document+scanners" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://lmgtfy.com/?q=portable+document+scanners" rel="nofollow">portable document scanners</a>&quot;, many of which allow you to insert a flat document into the scanner like a vending machine cash feed device. While there may exist such devices with dual scanning (for both sides simultaneously) most only scan one side at a time, so you still need to run the document through twice. </p><p><br /></p><p>&nbsp;But please, PLEASE, learn how to be a responsible collector who cares for the items you own. And <u>don&#039;t</u> put such collectibles through these devices, that&#039;s just plain dumb and it will only cost you the value of the items you have paid to put into your collection by introducing them to unnecessary damage.</p><p><br /></p><p>Take the time and the extra step to use a regular flat bed scanner. Don&#039;t be lazy about your collection if you are intent on handling it during the process of imaging your items. Most &#039;portable document scanners&#039; are not of particularly noteworthy optical capability. They are created for their convenience, and are not optimal devices for imaging, particularly when detail is something you may seek-- such as what most collectors like to see. </p><p><br /></p><p>As most scanners require a strong source of light to illuminate the document being scanned, in order to illuminate both sides simultaneously for quick scanning, you would soon realize that light from both sides at the same time would allow light from one side of the document to spill to the other side being scanned, interfering with the image on both sides, as the paper itself is semi-translucent. With a note you may get mixed scans of face details showing on the back and vice versa. Additionally, if a scanner were capable of scanning both sides through such a feed device, you&#039;d have a larger device overall, as all elements would need to be doubled, two camera lens and two lamps running together, more systems for dealing with two images at the same time, and also your costs for the device rise too. </p><p><br /></p><p>You can find perfectly useful and capable flat bed scanner and spend a wee bit more time scanning notes as everyone else does. Try putting as much effort into scanning and imaging your collection as you do creating these numerous questions threads of yours and you&#039;ll do just fine.[/QUOTE]</p><p><br /></p>
