HP printers and fax machines - Resolve fax problems
Resolve faxing issues such as faxes that do not send, printer not receiving faxes, poor fax quality, or error messages.
Cannot send faxes
Check the fax number, connection setup, and settings when faxes do not send.
Perform the following tasks in the order given. Test fax transmission after each task to see if the issue is resolved. You can send a test fax to the HP Fax Test Service at 1-888-HPFaxme (1-888-473-2963). This free service sends a return fax within 5 to 7 minutes when fax is working properly. Your fax number must match the number you entered in the fax header to receive the return fax.
Print a fax test report
Run a fax test from the printer control panel to identify issues with the printer, phone line connection, or fax settings.
-
On the printer control panel, select Run Fax Test or Fax Test Report in the Fax or Setup menu.
-
Review the report for any tests that failed and follow any instructions to resolve the issue.
Redial the number and change settings
To increase the chance of a successful fax transmission, send the fax again after adjusting settings.
Fax settings are in the Fax or Setup menus on the printer control panel.
-
Manually redial the fax number: Make sure you include any outside access code, such as '9', the long-distance country code, and the area code. If you are using speed dial, make sure the saved number has the required dashes between numbers.
-
Lower the fax speed: Using the slow or standard setting can improve sending success.
-
Turn on Error Correction Mode: If Error Correction Mode is off, turn it on to increase the chance of a successful transmission. The fax might take longer to complete.
-
Send the fax in black and white: The receiving fax machine might not support color faxes.
-
Confirm the dialing type (tone or pulse): Most phone lines use tone dialing.
-
Enable error reporting: The Fax Error Reports feature prints a report if an error occurs. If the error includes a numeric error code, go to HP Customer Support, and then search for the error code.
Check the fax connection
Check the phone line for issues.
-
Call the fax number from a phone: If you do not hear fax tones, the receiving fax machine might be turned off or disconnected.
-
Confirm the fax cords are in the correct ports: The phone line should be connected to the 1-LINE port and an answering machine or phone should be connected to the 2-EXT port on the back of the printer.
-
Connect a phone to the wall jack and try to make a call: If the call fails or there is no dial tone, check if another phone or device is keeping the line open. If you hear static, there might be interference from nearby electrical appliances, such as motors, fans, or televisions, or from coax cables. There might also be an issue with the line quality that requires attention from your phone service provider.
-
Use the fax cord that shipped with your printer: HP fax-capable printers ship with a two-wire phone cord. If you are using a different cord, confirm the connector does not have four wires. Shorter, higher quality cords work better than longer cords of lesser quality.
-
Remove other devices from the phone line: Devices such as answering machines, modems, or other telephones might cause faxing issues.
Reset the printer
Reset the printer to recover from printer errors or failures.
-
If your printer has a rechargeable battery, remove it.

Reconnect the power cord to a wall outlet and to the printer.
Note:
HP recommends plugging the printer directly into a wall outlet.
-
Turn on the printer to complete the reset.
Cannot receive faxes

-
Adjust the answering machine message length and clarity: To ensure the printer can detect fax tones, shorten the answering machine greeting message to 10 seconds or less, make sure there is no background noise, and leave 5 seconds of silence at the end.

Confirm the issue: Print a document or photo to make sure the issue is fax-related and not a printing issue.
-
If the issue occurs when receiving a fax, continue to the step to change the fax speed.
-
If the issue occurs when sending a fax, continue to the step to clean the scanner components.
-
-
Clean the scanner parts: Turn off the printer, and then use a clean, lint-free cloth, class cleaner, and distilled, filtered, or bottled water to clean the scanner glass, glass strip (if present), and white backing under the scanner lid until clean, dry, and streak-free. If your printer has an automatic document feeder (ADF), use a damp cloth to wipe the paper pick rollers and separator pad. Wait for all parts to dry before turning on the printer.
CAUTION:
To protect the interior parts, do not spray the cleaner directly on the glass or on the underside of the lid. Spray the cloth, and then wipe the scanner parts.

Turn on Error Correction Mode: If Error Correction Mode is off, turn it on to improve the fax quality. The fax might take longer to complete.
-
Update the printer firmware: Check for firmware updates in the ePrint, Setup, Service, or Settings menu on the printer control panel, or go to HP Software and Driver Downloads to install the latest version of your printer firmware.
If print quality is still unsatisfactory, service the printer.
Unable to fax with cell phone service and no landline
HP fax machines and fax-capable printers require a traditional landline telephone service. You might be able to fax with VoIP and DSL with the appropriate setup and equipment. Cellular networks currently do not support faxing from a printer.
To send a fax from your mobile device, download and install the HP Smart app from 123.hp.com and enable Mobile Fax.
Calls are interrupted by fax tones
Resolve fax tones interrupting voice calls or messages on a shared telephone line.
Fax settings are in the Fax or Setup menus on the printer control panel.
-
Use a different ring pattern. If a distinctive ringing service is available from your phone service provider, use a separate ring for faxes. The service assigns a second phone number to the same line that rings with a different pattern than the primary number.
-
Turn Auto Answer on. If this feature is not enabled, you must manually answer incoming fax calls. If you are using a distinctive ringing service, set the fax to automatically answer only the distinctive ring pattern.
-
Set the number of rings to answer incoming faxes. If you have an answering machine, allow it to answer all calls first so the printer can detect the fax tones after the machine answers the call. Change the Rings to Answer setting to a higher number of rings than the answering machine is set for.
-
Use the fax cord that shipped with your printer. HP fax-capable printers ship with a two-wire phone cord. If you are using a different cord, confirm the connector does not have four wires. Shorter, higher quality cords work better than longer cords of lesser quality.
-
Remove other devices from the phone line. Devices such as answering machines, modems, or other telephones might cause faxing issues.
-
Disable computer-based fax software. Fax software can interrupt fax calls to your printer or fax machine.
