Chapter 7

Another common problem is that HP software is not set as a trusted software by your firewall to access the network. This can happen if you answered “block“ to any firewall dialog boxes that appeared when you installed the HP software.

If this occurs, and if you are using a computer running Windows, check that the following programs are in your firewall’s list of trusted applications; add any that are missing.

hpqkygrp.exe, located in C:\program files\HP\digital imaging\binhpqscnvw.exe, located in C:\program files\HP\digital imaging\bin - or -hpiscnapp.exe, located in C:\program files\HP\digital imaging\binhpqste08.exe, located in C:\program files\HP\digital imaging\binhpqtra08.exe, located in C:\program files\HP\digital imaging\binhpqthb08.exe, located in C:\program files\HP\digital imaging\bin

NOTE: Refer to your firewall documentation on how to configure the firewall port settings and how to add HP files to the “trusted“ list.

Some firewalls continue to cause interference even after you disable them. If you continue to have problems after configuring the firewall as described above and if you are using a computer running Windows, you might need to uninstall the firewall software in order to use the HP device over the network.
