020H Fax Problems on Digital Networks RAP

Use this RAP to isolate fax problems when using digital networks.

The fax option was designed as an analogue Group 3 device. This will have the best performance when connected to a dedicated analogue phone Public Switched Telephone Network (PSTN) line or ‘Plain Old Telephone System’ (POTS).

• The fax option will function on the technologies that follow:

– Asymmetric Digital Subscriber Line (ADSL).
– Digital Subscriber Line (DSL).
– Voice Over Internet Protocol (VOIP).
– Fax Over Internet Protocol (FOIP), (T.38 protocol).
– T1 Trunk/E1 Trunk (Europe).

NOTE: Due to the compression used on the technologies, the level of performance will be lower than on a PSTN or POTS.

• The fax option will not function on Integrated Services Digital Network (ISDN).
• The fax over IP is a customer option. The feature allows the machine to send and receive faxes over an IP based network using SIP and VoIP Gateway industry standard protocols and services. The FoIP enabled machine can send and receive faxes from a variety of analog and digital devices.
Fax over IP uses devices at each end of the IP network (fax modems) to decode the fax audio (analog) back into fax protocol (digital), and send the data over an IP network. This is known as Fax Relay and ITU standard is T.38.
If the customer is experiencing poor performance when using fax over IP, it may be because the machine is configured for embedded fax. The machine cannot run both fax over IP and embedded fax concurrently, the machine must be configured for one or the other.

Initial Actions

WARNING: Ensure that the electricity to the machine is switched off while performing tasks that do not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause death or injury. Moving parts can cause injury.

• Switch off, then switch on the machine, GP 14.
• Check with the customer or IT person on what network the fax service is being used and what is the quality of service.
• Check that an analogue adapter or a connection for analogue terminals is available.
• Ask the customer to check with the service provider that an analogue port for fax service has been provided and enabled.


Perform the steps that follow:

1. From the Embedded Web Server Home screen, select Log In, then Admin. Enter the password ‘1111’ (default setting). Select Log In. Select Apps. From the Installed Apps list, select Fax. Disable Super G3.
2. If problems are still not resolved after these actions, escalate the problem using the normal escalation process.
