Hello,
Recently the network scanning functionality on my OfficeJet L7590 stopped working for no evident reasons (printing works just fine, physical scanner is also ok since copying works).
I have tried uninstalling/reinstalling the driver as well as running Print&Scan Doctor, and following some other advice I was able to find here, but without any success. Operating system is Windows 7 x64.
Actually the doctor complains that the driver cannot communicate with scanner (both with and without firewall disabled). But strange thing is that network capture shows nice 2-way communication on ports 9220, 9500 and 80. I am attaching the capture file here https://www.dropbox.com/s/4pdagls54khx6od/scantest.pcapng for a short Doctor session (Detect, Test scanning, Error, quit). In the capture, my PC has IP 192.168.0.101 and HP device is 192.168.0.105.
I will be very grateful for any suggestions.
