• If "Check whether there are any network problems." appears, the machine is not correctly
connected to the network or the settings of the machine are not correct. If you do not need to
connect to a network, you can specify the setting so this message is not displayed, and then the
[Check Status] key no longer lights. For details about how to do this, see "Parameter Settings", Fax
. If you reconnect the machine to the network, be sure to set "Display" by configuring the
appropriate User Parameter.
• If the paper tray runs out of paper, "There is no paper. Load paper." appears on the screen, asking

if the message appears on the screen. You can turn this function on or off with "Parameter Settings".
