General Troubleshooting
Fax Failure After Installation/Relocation
The Fax has failed to send after installation. The following troubleshooting
procedure applies to this error.
Initial Actions
• Disconnect all devices other than the Fax machine.
• Cycle printer power.
If the problem persists, use the following procedure.
The conventional analog telephone line uses standard RJ-11 cable, which has two
conductors. However, the four-conductor cables commonly available are backward
compatible with RJ-11 and can be used with no problems. On the other hand, since
these four-conductor cables are also used for ISDN systems, the number of
elements is not the key for identification of the type of line/service.
