Open your applications

Double click "Hewlett Packard"

Double click HP scan

(You may need to select the device)

Select "Document" or "Picture"

Hit Scan

Does this work?

If not go to your Apple menu> Software update

If it does, go to HP Utility (In the same Hewlett Packard folder listed above."

Select device

Select scan settings

Check the box that says "Enable front panel scanning"

When I try to select the device in the HP Utility, I get the message:  'HP Officejet Pro L7500' was disconnected.

When I press Start Scan on the device, I get the message:  No Connection to Computer.

I've checked the connections.  The device will print.

Follow the steps listed above for scanning through the software, tell me if that works.

I have tried those steps, with no success.  I can't get to scan settings.

When I click on "Open Scanner" under Print and Fax Preferences, I get the message "No Scanner Selected."
