HP OfficeJet Pro 7740 double side scan the top side of the scan is blured

[ralfsch]

I have since yesterday a HP OfficeJet Pro 7740 which could double side scan of documents. If I use double side scan of a double side printed document the top pages are  blured which means no text is written but I have some colored stripes in it. So my question is how I could correctly scan double side documents? 

Or do I have any thing forgotten to remove? I have not yet seen that I have some forgotten to remove from the scanner.

If the copy is working fine, follow the below instruction.

Hello,

thank you very much for your answer. I decided to call the HP support and with her help we found out, that the scanner did not work correctly. So today I become a replacement for the printer over the reseller. The new printer works as expected.

Thank you very much.

Best regards,

Ralf
