Cannot re-detect HP OfficeJet L7500 Scanner

A client could not start her Ethernet based Officejet Pro all in one scanner.  And here is what worked for me.

First uninstall all HP all in one software from the PC.

To completely uninstall the software, run the uninstaller at level three using these steps:

1. Turn the All-in-One off and disconnect any USB/Ethernet cable from All-in-One to computer.

2. Insert the all-in-one CD-ROM into the computer. Cancel any installation windows that appear.

3. Click Start on the taskbar and then click Run.

4. In the command box type the following command and press Enter key:

X:\Util\CCC\Uninstall_L3.bat

(X: is the CD-ROM drive letter of that the all-in-one CD-ROM is in)
