Hi,
I have a LJ1536 that worked fine until I had to replace my network router after it failed. Now I can print from both computers that I have in the same LAN, copy locally in the printer but not scan. The printer is connected to the router through a wireless AP configured as a client and wired to the printer. After router failed this AP had to be reconfigured for the new router.
I have tried scanning turning off firewall and anti-virus, removing and reinstalling all software using latest version on the web and nothing. HP toolbox FX works fine. HP Print and Scan Doctor didn't help. Service WIA is Started (auto mode) on the computers.
I receive the message on both computers when trying scanning:
Scanner Unreachable
Scanner communication cannot be established. Ensure your product is powered on, check the connection, and ensure your network is functioning properly. If these conditions are correct, restart the product and try scanning again.
If you are running firewall software, it may be blocking scan communication. Please visit www.hp.com/go/wirelessprinting for help configuring your firewall.
Configuration:
Windows 7 64 bits on both computers
LF1536 FW dated 1/14/2013
Any suggestion?
