I just installed Mavericks on my Air and now my HP Pro 8600 won't scan.
After I installed Mavericks on my Air I and try to scan, (I go to preferences, pull up the printer and click on scan) I get this message in the scanner window: "Failed to open a session on the device". I had no trouble on Lion.
