Late-breaking information
Known issues and workarounds
General
■ The SNMP Community Name can be set from the HP Toolbox software or the device embedded
Web server. If the Community Name setting is changed to something other than "public", network
scanning and faxing will stop working.
■ Firewall software can interfere with the HP software installer. If you do not disable the firewall during
install, you may see longer install times and failures to detect the device during a network install.
■ Certain high speed USB 2.0 cards ship with unsigned host controller drivers. If you have purchased
a USB 2.0 add-in card and have an unsigned driver, you may experience driver installation problems
or communication problems between the device and HP software. It is recommended that you
always use a Microsoft WHQL Certified host controller driver with your USB hardware.
