Engineering details It is sometime helpful to obtain detailed debug information from HP ToolboxFX. In this case it is necessary to do the following: 1. Shut down HP ToolboxFX by executing HPTLBXFX.exe shutdown. See A need to enable or disable HP ToolboxFX arises. 2. Edit the file: C:\Program Files\HP\ToolBoxFX\defaults\manifest.xml via Notepad or Wordpad as follows: Change: OFF 3 To the following: File 4 3. Run HP ToolboxFX From the Program Group, and reproduce the problem being debugged. 4. A debug file called ToolboxFXDebugLog.txt will be written to the following location: C:\Documents and Settings\All Users\Application Data\Hewlett-Packard\ToolboxFX\Logs USB drivers are unsigned The HP ToolboxFX for the HP LaserJet 3050/3052/3055/3390/3392 all-in-one communicates over USB connections by using a new, composite USB I/O. This version of HP ToolboxFX does not use DOT4, which will prevent issues previously observed on other products. However, this new I/O path requires that USB host controllers use signed USB drivers. Use the Windows Device Manager to choose a signed driver. If the host controller driver is not signed, obtain an updated Microsoft driver. For more information, see Port communication in the Engineering details chapter of this STR. A need to enable or disable HP ToolboxFX arises Some users might not use any of the features provided by the HP ToolboxFX, and might want to disable it in order to free memory and processing resources. To disable the HP ToolboxFX, follow these steps: 1. Use the Windows Search feature to find the hptlbxfx.exe application. Typically, this executable file is found in the following location: C:\Program Files\HP\ToolboxFX\bin 2. Click Start. ENWW Summary of HP ToolboxFX known issues 333
