Hp officejet 4500 scanning mac
This has worked before, with the same computer and scanner, so I'm trying to figure out what has changed, and how to fix it. In Preview, the File menu has an "Import from Officejet Gn-z" entry, which suggests that it recognises that this is a scanner. Selecting that menu entry gives the above error message.
I can access the HTTP interface of the device, which only shows information related to the printer part of it and the network configuration. Printing works fine. Looking at the network traffic with Wireshark, this generates a lot of traffic on port , as expected. Still it takes a few seconds for the error message to show up in the user interface.
Unfortunately I don't have a packet capture from the device when it's working properly. Googling this error message suggested resetting the printer drivers and restarting the computer, which didn't help. Having found an actual Windows machine, I tried running the tool again, but it didn't discover the printer. I had to install the driver in "Printers and scanners", click "Add printer" in order for the tool to discover the printer.
With the driver installed, the "doctor" said that the complete software for the printer was not installed, and provided a button for downloading and installing the software. With the "complete software" installed, the "doctor" showed a button labelled "Fix scanning". It ran a list of tests, not finding any problems. A test scan also worked well, and the Windows scan utility was also able to scan — but my Macbook still couldn't. Wireshark revealed that the Windows computer communicated with the scanner on port instead of port I'm not sure if OS X could be persuaded to do likewise.
It was working then it stopped and I scratched my head for a few months figuring it out.
The solution: re- enable T4NET protocol on port on the printer. Mac OSX is using it for the twain drivers.
