These communication errors might go away if you reboot your computer, but the only way to address
this problem is to have the optimal system configuration described above.
Another problem has been observed if you happen to have Microsoft .NET Framework 2.0 installed on
your system at the time that you install the HP ToolboxFX software. The HP ToolboxFX software will
still install the .NET Framework 1.1, since HP ToolboxFX will not utilize the .NET 2.0 Framework (due
to other problems). After the installation, if you run Microsoft Windows update, it will not recognize that
the .NET 1.1 framework requires .NET 1.1 Service Pack 1, and might not get all of the necessary security
updates either. Again, in these cases, the user might experience the intermittant

the device. error. The best recourse in this situation is to un-install the Microsoft .NET Framework 2.0,
run Windows update repeatedly to get the .NET 1.1 Service Pack 1 and all of the subsequent critical
security updates installed, and then run Windows update and reinstall the .NET Framework 2.0, which
is available as an optional update.
Alternatively, if un-installing the .NET 2.0 Framework is unacceptable, search the Internet for, and then
install the following Microsoft files:
●
NDP1.1sp1-KB867460-X86.exe
●
NDP1.1sp1-KB886903-X86.exe
These files will not display as necessary options to the .NET 1.1 Framework if the .NET 2.0 Framework
is installed. The Knowledge base article numbers to read are KB867460 and KB886903, which are,
respectively, Service Pack 1 for the .NET Framework and the current security patch.
Device communication
The majority of problems observed with HP ToolboxFX involve a lack of communication with the device.
In these cases, you should always check to see if the cables are plugged in, and the device is turned
on. Also, please see the above section regarding .NET Framework dependencies. If communication
problems are observed, particularly over a USB connection, the .NET Framework and Windows
configuration should be checked and updated if necessary.
Communication with the device can also be impacted if you change the IP address or hostname on a
network connected device. The HP ToolboxFX uses the properties stored by the print driver in order to
determine the device address. If communication errors are observed, you should attempt to print a test
page to the device from the computer. If a page cannot be printed, it might be that the address or port
