My OS is Mac OS X 10.7.3, Lion. Our new HP OfficeJet 6500A prints OK, but will not scan: Message on the printer front panel is "No Computer Detected," message in the iMac Open Scanner window is "Failed to Open a Session on the Device." When I atttempt to scan, the printer and computer lose their wireless connection. Is this a Lion problem or an HP 6500A problem? How fix?

Quick update: Turning the printer off and then back on solved the problem, at least temporarily. It scanned! Does anyone have a more permanent solution? Thanks — j-k

Hi, SeanS: Thank you. Is there a similar document for the Mac OS? This one addresses only Windows, and I'm on an iMac with OS 10.7.3 (Lion).
(Turning the printer off and then back on solved the problem a couple of days ago, so that is a workaround. I just wonder if there's some underlying flaw in the connection, installation, driver, etc., that we can correct.)
