Unable to
communicate (IP
fax (SIP))
The machine is turned off.
The machine cannot receive a fax when
turned off. Turn the machine on.
The machine is in the System
Administration mode.
The machine cannot receive a fax in the
System Administration mode. Exit the System
Administration mode.
A wrong machine password
has been set.
When a machine password has been set, the
machine accepts only data or polling fax sent
with the correct machine password in F code.
IP fax (SIP) is being sent.
The number of simultaneous connection for
IP fax (SIP) is one. The machine cannot send
and receive an IP fax (SIP) at the same time.
Wait until the sending completes, and then
ask the sender to send again.
The network relay device such
as a switch, router, and
firewall cannot go through
the port of the machine.
Enable the port for IP fax (SIP) of the
network relay device.
The IP filter setting of the
machine is incorrect.
Add the IP address of the SIP server to the
permitted IP address of the machine in the
environment where the SIP server is used. Set
[IP Filtering] under [Properties] tab >
[Security] using CentreWare Internet
Services.
The Ethernet cable has been
unplugged for more than one
minute.
When Register recovery on the SIP server is
completed, the registration succeeds. No
measure is required.
Unable to
communicate (IP
fax (SIP) via a
VoIP gateway)
The registration of VoIP is
incorrect.
Register the correct VoIP gateway on the
machine.
The specified VoIP gateway
in a network is not active.
Consult your network administrator on the
VoIP gateway condition.
The settings on the VoIP
gateway are incorrect.
Consult your network administrator on the
VoIP gateway settings.
IP fax (SIP)
transmission
takes long time.
The priority of the IP packet,
which is sent from the
machine, on the network
relay device (such as a switch
and router) is low because the
QoS setting of the machine is
invalid.
Increase the value for [Prioritize IP Packets]
according to your network environment.
For more information on [Prioritize IP Packets], refer to
"Prioritize IP Packets / Prioritize IP Packets (Ethernet 1),
Prioritize IP Packets (Ethernet 2)" (P.191).
A large amount of
communication data loss
occurs because the queue
(buffer) assigned to each QoS
of the network relay device
(such as a switch and router)
is low.
Set an appropriate parameter on the network
relay device for your network environment.
