updates are installed. Again, in these cases, the user might experience the intermittant Cannot connect
to the device. error. The best recourse in this situation is to uninstall the Microsoft .NET Framework
2.0, run Windows update to install the .NET 1.1 Service Pack 1 and all of the subsequent critical security
updates, and then run the Windows update and reinstall the .NET Framework 2.0, which is available as
an optional update.
Alternatively, if uninstalling 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 do not appear as necessary options to the .NET 1.1 Framework if the .NET 2.0 Framework
is installed. The related Knowledge base article numbers are KB867460 and KB886903, which discuss
Service Pack 1 for the .NET Framework and the current security patch.
Device communication
The majority of problems observed with HP ToolboxFX involve broken communication with the device.
In these cases, always check to make sure that the cables are plugged in and that the device is turned
on. Also, see the preceding section about .NET Framework dependencies. If communication problems
are observed, particularly over a USB connection, the .NET Framework and Windows configuration
should be checked and updated as necessary.
Communication with the device can also be impacted if the IP address or hostname is changed on a
network connected device. The HP ToolboxFX uses the properties that the print driver stores in order
to determine the device address. If communication errors are observed, print a test page to the device
from the computer. If you cannot print a test page, the address or port for the print driver might not be
configured correctly. Turn the computer of and then on again after reconfiguring the print driver in order
for HP ToolboxFX to resume communication with the device.
