Try the following:
- Make sure the LINE port on the WorkForce is connected to a telephone wall jack.
- Verify that the telephone wall jack works by connecting a phone to it. If the line has static, turn off the V.34 and ECM (Error Correction Mode) settings.
- If the WorkForce is connected to a DSL phone line, you must have a DSL filter connected to the phone jack. Contact your DSL provider for the necessary filter.
- If you answer the phone and hear a fax tone and the call disconnects when you hang up, make sure there is a phone or answering machine connected to the EXT. port on the WorkForce.
- Make sure that your recipient’s fax machine is turned on and working.
- Make sure paper is loaded correctly.
- If you’re using DRD (Distinctive Ring), try setting DRD to OFF or ALL. If the fax answers when turning off DRD, the ring pattern may be causing the problem. Contact your phone company.
- If a telephone with an answering machine is connected to the WorkForce, set the number of rings on the WorkForce to more than the answering machine and turn Auto Answer mode on (on the WorkForce).
- Turn call waiting off. Call waiting may disrupt an incoming or outgoing fax.
- If the WorkForce does not receive a fax, verify that it’s not connected to a PBX system. The ring signal on a PBX system can cause a problem. Contact your PBX administrator for support.
Note: Because fax machines are designed to work over standard analog telephone lines, Epson does not guarantee that fax transmission will work over VOIP phone lines (cable systems such as, Cox, Charter, Time Warner, Comcast, FIOS, Vonage).
