Common problems for fax machines include image quality, paper jams, connectivity issues, or sending and receiving errors. You may see these error messages: Fax communication error.
Check for phone line connection issues that might cause fax receiving to fail. Confirm the fax cords are in the correct ports: The phone line should be connected to the 1-LINE port and the answering machine, if used, should be connected to the 2-EXT port on the back of the printer.
Why? Windows can detect and “sort of” support your printer – the Windows Drivers may not be enough to allow the printer to be designated as the “Default Printing Device”. Without this designation, the “Fax” portion of the printer might think it is the default printing device.
Faxes can fail for a variety of reasons, such as sending to a non-working or non-fax number, a recipient listing their number on the National Do Not Call List, a recipient line being continually busy or out of paper, or if there is noise or interference on the line.
If received faxes seem to be going through, but isn`t printing and there is no error message, refer to Faxes are received but not printing out (Fax Preview)(Opens in a new tab) to confirm that the Fax Preview feature isn`t enabled. – If Fax Preview was enabled and you`ve disabled it, have a fax sent to you.
To test a fax machine simply fax to somebody else with a fax machine – and have them send a reply fax back to you. When sending the fax, turn on the confirmation page feature – a successful confirmation page shows that the fax machine on the other end has successfully received the message.
Faxes can fail. Sometimes it`s for obvious reasons such as busy signals or disconnected fax numbers but there are other reasons a fax may fail and we`ll go into why some fax services are not the same as others.
A printer has to have fax capabilities to be able to fax documents, so it`s necessary to first determine if your printer is fax-enabled. Multifunction printers usually have “fax” buttons sitting next to the scanner.
The Failed (Fax negotiation failed) error could occur for different reasons: • The system initiated a fax transmission but could not synchronize with the far-end fax. • A remote fax machine was detected, but the sending and receiving modems could not establish communication.
Check the fax line with a phone

If you use traditional analog technology to send a fax, you can test the fax line by making a phone call. Dial the recipient`s number and listen to a fax machine`s sound. The fax line is active and working if you hear a tone or beeping sound.

“Fax, no printer” is a slang term expressing a strong sense of agreement similar to saying “that`s the truth” or “you`re absolutely right.”
Send a test fax: Send a one-page, black & white test fax to 1-888-HPFaxme (1-888-473-2963 U.S.). The service receives and returns faxes within 5 to 7 minutes to the fax number in the fax header.
It`s easy for faxed documents to get lost. A fax number can be incorrectly dialed, leading for a file to get sent to the wrong place. The document can also get misplaced once it makes it to the desired location.
What are the disadvantages of fax machines? Requires a landline phone number: A fax machine cannot operate unless it is connected to a landline phone number. Not scalable as your business grows: With a traditional fax machine, there is no option to send a fax to multiple recipients at once.
Receiving a Fax

If the machine is set to automatically answer the phone line, when the fax rings it will automatically receive the fax and print it off.

In most computer-based web browsers, to open menus used to clear your cache, cookies, and history, press Ctrl-Shift-Delete (Windows) or Command-Shift-Delete (Mac).
Open the document tray, and then the Control Panel. Wipe dirt off the machine using a slightly damp clean cloth. Clean the white bar and the glass cover. Moisten a small piece of clean soft, lint-free cloth with isopropyl alcohol and carefully remove dirt from the glass cover and the white bar of the scanner.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

The fact your computer connects to the machine via WiFi is what makes it wireless. You will still need to plug your machine into a phone jack if you want to fax via a WiFi printer. Wirelessly faxing from a printer is only possible without a phoneline connection if you connect via a cellular network.
Receiving Faxes

If you do need to receive faxes, you`ll have to sign up for a paid service. The service will need to establish a dedicated phone number for your fax line, and that costs money. RingCentral, MyFax, and many other services will do this if you pay.

A possible reason the faxes you send may be blurry is if you`re receiving image-heavy documents. Because most fax machines aren`t equipped to handle printing images, you`ll want to send high-resolution color faxes in order to eliminate the blur.
Typically faxes take 30-60 seconds to transmit when scanned in the recommended format of black & white at 200-300 DPI (dots per inch) resolution.
The fax detection feature detects whether an inbound call is from a fax machine. If the inbound call is from a fax machine, the call is rerouted appropriately.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
