I have an HP 2840 all-in-one and have a problem with the scanning function. It is currently USB attached to my desktop computer.
I have (prior to this week) been able to place documents in the auto feeder, press the Scan button and have them scan into my system (it prompts me on my desktop, and I save the scan to a file). I was prompted for a file name and location. All was lovely.
Now, I can only scan documents if I keep the HP Director software open on my desktop. The process is longer and slightly more cumbersome. If I do not have the HP Director software open on my desktop, the unit displays "Waiting for PC" for approximately 15 seconds, then nothing happens.
I'm thinking I changed a setting somewhere.
Any ideas out there?
