your Microsoft Windows XP Service Pack 2 (SP2)-based computer, infrared
communications may no longer work. You cannot use the infrared port to transfer
data. If you delete the infrared device and then restart the computer, infrared
communications work. However, if you restart the computer again, infrared
communications no longer work.Note
When this problem occurs, you can still use infrared
communications to print. Infrared printing is not affected by this problem.
