Re: lexmark 7300 - high pitched tone
RF sources can transmit energy into cables, PCB (printed-circuit-board) traces, and ICs.
Symptoms of RF susceptibility can be tricky to diagnose.
The best technique is to kill noise at its source.
Shielding is a high cost Band-Aid.
Careful layout and good system design can provide the best protection from RFI (radio-frequency interference).
Sidebars: Insidious RF Steady streams of RF energy constantly engulf your electronic system. Some of this energy comes from the accidental byproduct of a system; other RF sources, such as radios and radar, intentionally radiate energy. Some RF sources are so strong and so insidious that they create noise in simple wires, such as the magnet wire that forms the voice coil of a speaker. It is merely annoying for consumers to hear noise in their home-audio systems. However, RF noise that causes a machine to go haywire or an airplane’s instruments to malfunction could imperil or even kill people. For this reason, the European Union and the United States instituted RFI (radio-frequency-interference) testing for products that vendors sell there. When the European Union more than a decade ago instituted the CE (Conformité Européenne) immunity-compliance tests, engineers soon learned that passing them is more difficult than passing the US FCC (Federal Communications Commission) noise-radiation tests. “Engineers don’t think it is a problem until it is a problem for them,” says Steve Bible, Microchip Technology’s technical-staff engineer. “They are in a real time crunch. They have made a bad design, and it’s hard to convince them that it’s bad. They want to find that one silver bullet—the one thing they can do so they can pass—except there is no silver bullet.”
To provide your systems with robust RFI immunity, you must understand just how many RF sources your system is subject to. The electric-power industry broadcasts 50- or 60-Hz radio waves as it

Make sure the that the fax line is working. To check, insert a telephone device straight to the fax line. You should get a dial tone.
Make sure the telephone cord from the phone jack in the wall is plugged into the Line port on the back of your Lexmark printer.
Assign the correct fax number on the printer.
If you have an answering machine connected to the same
line as the fax, set the answering machine to answer incoming calls before the printer does. Increase
the number of rings by a factor of 3 over the answering machine. For example, if the answering
machine is set to pick up on 4 rings, set the printer to pick up on 7 rings.
If you have a voicemail feature in the same line as the
fax, you may subscribe from your phone service provider for a distinctive ring
pattern feature. You can program your printer to have a distinctive ring
pattern and phone number for incoming faxes.
If these don't help, please contact Lexmark Technical Support Center for additional assistance.
When you ring it from your biz line, does it pick up? If you're using a high speed dsl line, you'll need to put the machine where a normal phone would go. You should be able to ring the machine using our cell phone. If the machine indicates an incoming call, but still doesn't pick up, check the settings and make sure it isn't set to manual instead of automatic fax pickup.
Open the Lexmark "Fax Printer Setup Utility". Click on the "Connection/Dialing" tab. In the "Interact with Phone Line" section, "Answer Incoming Calls:" should be set to "If fax tones are detected".
If this is turning out to be too unreliable for you, you will need to either manually receive incoming faxes (by changing the setting to "Manual"), or you will need to at least spring for a separate phone number with a distinctive ring for incoming faxes.
Hi,welcome to fix ya. if this is a bose system you have a bad amp behind the rear seat they short out inside and cause the speakers to emit a high pich squeel. you can buy these amps on e-bay pretty cheaply or send it to bose for repair .
did you put the originals page(s) in the machine FIRST to fax, then enter the number then press start?
If you enter the phone number 1st BEFORE putting your originals in the feeder, the machine thinks you want to make a copy.
The FAX Mode is the setting for incoming faxes.
Try that and let me know if it works.
There should also be a button called "Hook" or "speaker" or something that you hit and you will hear the dial tone.
Once you hear the dial tone, you can dial the number, (make sure the pages you want to fax is in the feeder.
Once you hear the fax high pitch noise, hit the start button.
Hope this helps. Let me know if it does and also remember to leave a feedback and rating if I have helped you. Thanks and good luck.
It sounds like maybe the printer is not picking up the incoming call. Check to see that the printer is the first thing connected to the phone jack. If you have DSL you will need to plug the printer into the "phone" side of the DSL filters that you have on all your phone jacks. If you have an answering machine it should be plugged into the printer's phone jack - not the other way around. The printer is smart enough to pick up fax calls and pass voice calls on to the answering machine if you get it hooked up right. Check the user's guide for more specifics.
