Troubleshooting and Routine Maintenance Telephone Line or Connections Difficulty Dialing does not work. (No dial tone) The machine does not answer when called. Suggestions Check that the machine is plugged in and that the On/Off key is on. Check all line cord connections. Make sure the telephone line cord is plugged into the telephone wall jack and the LINE jack of the machine. (Canada only) Change Tone/Pulse setting. (See the Quick Setup Guide.) Verify that the telephone line and jack are working by connecting a known working B telephone and telephone line to the jack. Press Speaker Phone or lift the machine's handset, the cordless handset or the handset of an external telephone, and then listen for a dial tone. If there is no dial tone, ask your telephone company to check the line and/ or jack. Make sure the machine is in the correct receiving mode for your setup. (See Choose the correct Receive Mode on page 45.) Check for a dial tone. If possible, call your machine to hear it answer. If there is still no answer, check that the telephone line cord is plugged into the telephone wall jack and the LINE jack of the machine. If there is no ringing when you call your machine, ask your telephone company to check the line. Receiving Faxes Difficulty Cannot receive a fax. Suggestions Check all line cord connections. Make sure the telephone line cord is plugged into the telephone wall jack and the LINE jack of the machine. Make sure the machine is in the correct receiving mode for your setup. (See Receive mode settings on page 48.) If you often have interference on the telephone line, try changing the menu setting of Compatibility to Basic(for VoIP). (See Telephone line interference on page 151.) Sending Faxes Difficulty Cannot send a fax. Transmission Verification Report says 'Result:NG'. Suggestions Check all line cord connections. Make sure the telephone line cord is plugged into the telephone wall jack and the LINE jack of the machine. Make sure that the Fax key is illuminated. (See Entering Fax mode on page 36.) Ask the other party to check that the receiving machine has paper. Print the Transmission Verification Report and check for an error. (See Reports on page 89.) There is probably temporary noise or static on the line. Try sending the fax again. If you send a PC FAX message and get 'Result:NG' on the Transmission Verification Report, your machine may be out of memory. To gain extra memory, you can turn off Memory Receive (see Turning off Memory Receive Operations on page 53), print fax messages in memory (see Printing a fax from the memory on page 58) or cancel a Delayed Fax or Polling Job (see Canceling a fax in progress on page 38). If the problem continues, ask the telephone company to check your telephone line. If you often get transmission errors due to possible interference on the telephone line, try changing the menu setting of Compatibility to Basic(for VoIP).
