Only scans 1/2 back page in duplex scan.

There is option to skip Blank pages. You have to specify in terms of percentage, above which the scanner will save and discard images below the specified percentage.

Pls check if you have selected 'duplex' scanning. The extra page could be back side image! Clean the glass images without lines.

What scanning software are you using? In Adobe Acrobat Professional 9, you can set up different scan profiles, including duplex scanning. The sheet feeder holds up to 50 pages; you just tell the software to make all pages one pdf.

Check your scanner software settings. It is probably set at duplex ever time you start to scan. That is why you get two pages for every pass, the front and the back. You must place the document in the feeder in a way that the front side of the document is page 2. You may want to flip it next time you scan. So the main question is why there is black line from top to bottom? That is because there is a piece of dirt stuck on the glass of the scanner. You see, this scanner actually does two scanning when a page runs through it: the front and the back in duplex mode. So there are two scanners in side the box. The front page scanner apparently is dirty and needs to be cleaned with clean cloth and lens cleaner.

Check your brightness setting for backside. Ideally keep it automatic, else you can manually choose the right brightness.

Check your scanning software settings. If you are getting only one file output, then you must have chosen 'multipage' option.

The scanner can scan in either simplex or duplex mode only. If blank page is scanned, then it will appear BLANK, else someone would say, my scanner is not scanning properly! Remove balnk pages using software or sort on file size and delete the small sized files. Take care to ensure they are really blank.

Try scanning a double sided document in duplex mode. Reverse the page and scan again. Make sure contrast/rightness settings are okay. If one side output is still not okay, then it possible that the lighting has failed. Either loose contact or failure of the lamp. Some scanners have LEDs and some have a lamp.

You may want to try using Laser Fiche. This scanning software allows you to select "Duplex" which allows you to scan double sided document

Wow, it's been so long since I posted this, I cannot remember! I am the tech person and just was relaying the problem as an EX exployee relayed it to me. What did my original message say? I BELIEVE it was 1/2 black, but no image/words on the other half. Just black and white, but again, I cannot remember. Does it make a difference?
