Query: Excellent Printer - Install Carefully

Bought the 2710 about a month ago. Installed easily (wired network), works beautifully. Photos look great even without special photo cartridge! Only recently tried to use scanner and found that it did not work. Other system prolems were also apparent. After lengthy investigation with tech support, we determined that problem was interference from McAfee during install (although I had 'disabled' it). Uninstalled Mcafee, reinstalled software; now works perfectly. An excellent product! I just wish tech support was in the US (got a follow-up call from them at 1:00 am this morning!).
