I cant seem to set up my fax for incoming

I would NOT unistall the program...

You can start the HP LaserJet Fax Setup Utility by clicking Start , selecting Programs or All Programs , selecting HP , selecting the name of the product, and then clicking HP Fax Setup Wizard

HP recommends that you run the utility to configure the fax settings for both the software and the product control panel. Run the utility even if you have already configured the fax settings. The settings in the HP LaserJet Fax Setup Utility are used by HP ToolboxFX to run other faxing features, such as the fax cover page.

If you want to follow HP's step by step instructions, follow this link...

Uninstall printer prog restart, then reinstall printer programme. This time sit with computer while prog installs, it will ask you question once whole prog installs, you most likely missed the information to install for the fax part?
