Running WireShark while running the utility shows a Simple Service Discovery Protocol multi-cast request sent out to 239.255.255.250 on the local network as follows: I've tried HP Print and Scan Doctor (v5.2.1) and it detects a another HP printer that I have on the network, but not the HP ScanJet 4500 fn 1 :-(. Urn:uuid:b05117ac-9988-4ec8-a22a-2be3b5b781f4Īnd the scanner returns a HTTP 500: Internal Server Errorĭoes anyone know what I might be doing wrong, or whether this is a known issue with the ScanJet 4500 (or HP scanners in general)? And if so, is there a workaround to get network scanning working? Urn:schemas-xmlsoap-org:ws:2005:04:discovery However, when I try to connect the scanner in the HP setup software it fails to find it by discovery or by specific IP address / hostname:Īs an investigation step I've installed WireShark on my laptop and found that when I click 'Search' in the dialog above it sends a HTTP request to the scanner as follows: POST /StableWSDiscoveryEndpoint/schemas-xmlsoap-org_ws_2005_04_discovery HTTP/1.1 I've installed all of the latest HP software (v) and flashed the firmware on the scanner to the latest version (v7.128), and I can successfully ping the scanner by IP and hostname, and I can also browse the scanner's web-based admin interface without issue so the scanner seems to be running ok. In short, I bought a new HP ScanJet Pro fn 1 a couple of years ago but I could only ever get it working via USB, and I'm now trying (unsuccessfully) to get it working as a network scanner with a brand new Windows 10 laptop. I recently posted a question on the HP community support forum ( see this), but past experience suggests I might get a better response here :-).
