Verifying fax operation
When the fax accessory is installed and operating correctly, the fax icon displays on the MFP control
panel. If the fax accessory has just been installed but has not been configured, the fax icon is grayed-
out and (depending on the MFP model) may have Not Configured written across it. If this occurs, the
fax accessory needs to be configured, see
Required fax settings on page 36 .
