Unable to communi-
cate (IP fax (SIP) via
VoIP gateway).
Register the correct VoIP gateway on the machine.
Confirm with your network administrator whether the VoIP gateway is working properly.
Confirm with your network administrator whether the VoIP gateway settings are correct.
The destination G3 fax machine is not working properly. The data cannot be sent if the G3 fax
machine of the recipient is turned off. Call the recipient to confirm the machine condition.
IP fax (SIP) transmis-
sion takes a long time.
Increase the value for [Prioritize IP Packets] of the machine according to your network environ-
ment.
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.
A large amount of communication data loss occurs because the communication rates differ
within the network.
Use the same communication rate 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 parameters on the VoIP gateway for your network environment.
IP fax (SIP) machine is connected to the data network if 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.
Communication/call,
other than IP fax (SIP)
communication, in
the network is slow
when IP fax (SIP)
communication is
executed.
Decrease the value for [Prioritize IP Packets] of the machine according to your network environ-
ment.
IP fax (SIP) machine is connected to the voice network if 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.
The image quality is
poor.
The drum cartridge is damaged.
Copy a document. If the image quality is poor, replace the drum cartridge with a new one.
The document glass of the sender’s machine is dirty, or the resolution setting on the sender’s
machine is too low.
Check the machine condition with the sender.
Note
During communication, image quality problems may be caused by a problem
with the sender’s machine, not just by a problem of the machine.
The one-page docu-
ment is received split
into multiple pages.
You can set the machine to process the received documents by using a combination of the
Auto Reduce on Receipt feature and a border limit value for page splitting.
According to the setting combination specified, the received document is printed as follows.
Symptom
Cause/Remedy
Auto Reduce on Receipt ON
Auto Reduce on Receipt OFF
Within border limit
Automatically reduces image
size and prints it on one page
Trims the portion exceeding
standard size and then prints it
Exceeding border limit
Splits data at an equal ratio and
prints it
