IP fax (SIP)
transmission takes
long time. A large amount of
communication data loss
occurs because the
communication rates (10M/
100M/1000M) differ on two
sides of the network relay
device (such as a switch and
router). Use the same communication speed within
the network.
A large amount of
communication data loss
occurs because the
communication parameters
(such as input gain, output
attenuation, echo setting) of
the VoIP gateway are
inappropriate for the network
environment. Set appropriate communication parameters
on the VoIP gateway for your environment.
IP fax (SIP) machine is
connected to the data
network where the telephone
and data networks are
operated separately. Configure the QoS setting for the entire
network environment and control traffic. Set
[Prioritize IP Packets] for QoS of the machine.

For more information on [Prioritize IP Packets], refer to
"Prioritize IP Packets / Prioritize IP Packets (Ethernet 1),
Prioritize IP Packets (Ethernet 2)" (P.250).
Communications
other than IP fax
(SIP) become slow
while IP fax(SIP)
transmission is
executed. The priority of IP packet,
which is sent from the
machine, on the network
relay device (such as a switch
and router) becomes higher
than necessary because the
QoS setting of the machine is
invalid or a large amount of
buffer space is occupied. Decrease the value for [Prioritize IP Packets]
according to your network environment.

The image quality
is poor. The document glass is dirty. Clean the document glass.
Reference
z Refer to Cleaning Document Cover and Document Glass
(P.111).
The fax density is
inappropriate. Adjust the fax density.
Reference

Refer to "Fax" > "Fax/Internet Fax" in the User Guide.
The image quality
is poor. The sender's machine has a
problem. Confirm with the sender.
Note
z
Image quality may be affected by a problem
of the sender's machine, not just by a problem
of the machine.
