When I run the Firmware update tool or the I-FAX install tool, the "Program failed to run" message appears on my PC screen. What do I do?

A message appears informing to "The optical photoconductor needs to be replaced./ The paper tray is almost empty. " on my Macintosh.

The error message "Invalid format for short nick name" appears when printing a document. (Mac OS X 10.5 or greater)

I configured the "IP Config" method of the machine to "Auto" to assign an IP address automatically, however it was changed to "Static" unexpectedly. I get an error message that indicates IP address is not unique, or a document is printed out by the machine I didn't expected.

My Antivirus Software gives a warning message during the installation of Web BRAdmin.
