Setting up fax in countries or regions with different telephone wall jacks and plugs

Note:  These instructions apply only to printers that support analog fax. For more information, see Supported fax.

CAUTION—SHOCK HAZARD:  To avoid the risk of electrical shock, do not set up this product or make any electrical or cabling connections, such as the power cord, fax feature, or telephone, during a lightning storm.

CAUTION—SHOCK HAZARD:  To avoid the risk of electrical shock, do not use the fax feature during a lightning storm.

CAUTION—POTENTIAL INJURY:  To reduce the risk of fire, use only a 26 AWG or larger telecommunications (RJ-11) cord when connecting this product to the public switched telephone network. For users in Australia, the cord must be approved by the Australian Communications and Media Authority.

The standard wall jack adopted by most countries or regions is RJ‑11. If the wall jack or equipment in your facility is not compatible with this type of connection, then use a telephone adapter. An adapter for your country or region may not come with your printer, and you may need to purchase it separately.

There may be an adapter plug installed in the telephone port of the printer. Do not remove the adapter plug from the telephone port of the printer if you are connecting to a serial or cascaded telephone system.

Connecting the printer to a non‑RJ‑11 wall jack

  1. Connect one end of the telephone cable to the line port of the printer.

  2. Connect the other end of the cable to the RJ‑11 adapter, and then connect the adapter to the wall jack.

  3. If you want to connect another device with a non‑RJ‑11 connector to the same wall jack, then connect it directly to the telephone adapter.
