Troubleshooting and routine maintenance Phone Line or Connections Difficulties Dialing does not work. The machine does not answer when called. Suggestions Check for a dial tone. Change Tone/Pulse setting. (See the Quick Setup Guide.) Check all line cord connections. Check that the machine is plugged in and switched on. Send a manual fax by pressing Hook or by lifting the handset of the external phone and dialing the number. Wait to hear fax receiving tones before pressing Start. Make sure the machine is in the correct receiving mode for your setup. (See Receiving a fax on page 40.) Check for a dial tone. If possible, call your machine to hear it answer. If there is still no answer, check the telephone line cord connection. If there is no ringing when you call your machine, ask your telephone company to check the line. Sending Faxes Difficulties Poor sending quality. Transmission Verification Report says 'RESULT:NG'. Vertical black lines when sending. Suggestions Try changing your resolution to Fine or S.Fine. Make a copy to check your machine's scanner operation. If the copy quality is not good, clean the scanner. (See Cleaning the scanner glass on page 128.) 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 free up extra memory, you can turn off fax storage (see Turning off Remote Fax Options on page 66), print fax messages in memory (see Printing a fax from the memory on page 45) or cancel a delayed fax or polling job (see Checking and canceling waiting jobs on page 38). If the problem continues, ask the telephone company to check your phone line. If you often get transmission errors due to possible interference on the phone line, try changing the Compatibility setting to Basic. (See Phone line interference on page 115.) If the copy you made shows the same problem, clean the scanner. (See Cleaning the scanner glass on page 128.) Handling Incoming Calls Difficulties Suggestions The machine 'Hears' a voice as a CNG Tone. If Easy Receive is set to on, your machine is more sensitive to sounds. It may mistakenly interpret certain voices or music on the line as a fax machine calling and respond with fax receiving tones. Deactivate the machine by pressing Stop/Exit. Try avoiding this problem by turning Easy Receive to off. (See Easy Receive on page 42.) Sending a Fax Call to the machine. If you answered on an external or extension phone, press your Fax Receive Code [default setting is (l 51)]. When your machine answers, hang up. 103
