Xerox Printer Troubleshooting Guide
How to Troubleshoot Fax Problems on Xerox Printers
Reviewed June 2026
Fax problems on Xerox printers usually fall into one of a few categories: the fax line is not working correctly, the fax number or dialing format is wrong, the Xerox fax settings need review, or the fax hardware needs service. The fastest way to avoid wasted time is to first determine whether the issue affects sending, receiving, or both.
Important: Menu names and fax settings vary by Xerox model. Some devices use a traditional phone-line fax connection, while others may use internet fax or network-based fax workflows. This guide focuses mainly on standard send-and-receive fax problems on Xerox devices. Some steps may require administrator access or help from the customer’s phone or fax service provider.
Quick Answer
If a Xerox printer cannot send or receive faxes, start by confirming whether the problem is outgoing, incoming, or both. Then verify the fax number and dialing format, test the fax line by calling it from a phone, and send a small one-page test fax. If the fax number does not answer with fax tones, or if the line gives a busy signal, keeps ringing, or goes to voicemail, the issue is likely with the fax line or service provider rather than the Xerox device.

Symptoms This Guide Covers
This guide may help if you are seeing any of the following issues:
- The Xerox printer cannot send a fax.
- The Xerox printer cannot receive a fax.
- Faxing works only sometimes.
- The machine dials, but the fax never completes.
- The fax line sounds wrong when tested.
- The fax number rings but does not connect properly.
- Incoming faxes do not arrive.
Applies To
This guide applies to Xerox printers and multifunction devices with fax capability. It is most useful for standard phone-line fax troubleshooting, but some steps may also help where fax-related workflows depend on network settings or internet-fax features.
What Kind of Fax Problem Are You Seeing?
Use this table to quickly separate line problems, dialing problems, settings problems, and device-side issues.
| If This Is Happening | Likely Issue | What To Check First |
|---|---|---|
| The machine cannot send any faxes. | Fax line, dialing format, fax setup, or fax hardware. | Verify the destination number, dialing prefix, line connection, and one-page test fax. |
| The machine can send faxes but cannot receive them. | Incoming line, receive mode, voicemail, call routing, or service-provider issue. | Call the fax number from a phone and listen for fax tones. |
| Only one destination fails. | The receiving fax number, remote fax machine, or destination-side service may be the issue. | Try a different known-good fax number before changing Xerox settings. |
| The fax number keeps ringing or goes to voicemail. | The fax line may not be answering as a fax line. | Contact the fax or phone service provider. |
| Faxing stopped after an office move, service change, or outage. | The line, routing, fax number, or service configuration may have changed. | Confirm the correct line is connected to the correct fax port and test the line directly. |
| The fax workflow depends on internet fax or network fax features. | Network, server, email, or internet-fax configuration issue. | Confirm the printer network connection and review the related server or workflow settings. |
Before You Start
Before changing settings, confirm a few basics:
- Is the issue with sending, receiving, or both?
- Is the device connected to a traditional fax line, or is the workflow dependent on network or internet fax features?
- What is the correct fax number for the machine?
- Did the problem begin after a service change, office move, outage, or settings change?
- Is the issue happening every time or only occasionally?
This matters because a line problem, dialing problem, settings problem, and hardware problem do not behave the same way.
Step 1: Identify Whether the Problem Is Sending, Receiving, or Both
Start by narrowing the issue. Ask:
- Can the customer send faxes but not receive them?
- Can the customer receive faxes but not send them?
- Are all outgoing faxes failing?
- Are all incoming faxes failing?
- Does the problem happen with one destination only, or with every fax number?
If only one destination fails, the issue may be on the receiving side. If every outgoing fax fails, the problem is more likely with the Xerox device, the fax line, or the dialing setup.
Step 2: Check the Physical Fax Line and Basic Device Status
Confirm that the fax line is connected to the correct port on the Xerox device. If the line is connected to the wrong jack, faxing may fail even when printing and scanning still work.
Also check the following:
- The printer is powered on and fully ready.
- There are no active fault messages blocking fax use.
- The machine does not show a fax-related alert.
- If applicable, the fax option, fax card, or fax hardware is present and recognized.
Tip: A Xerox device can print normally and still have a fax-specific issue. Do not assume the fax line is working just because the printer is online and printing.
Step 3: Verify the Fax Number and Dialing Format
Double-check the number being dialed. Look for common issues such as:
- The fax number was typed incorrectly.
- An outside-line prefix is needed, such as dialing 9.
- The area code was omitted.
- Long-distance dialing rules changed.
- The number saved in the address book is outdated.
If the dialing format is wrong, the fax may fail even when the line itself is working properly.
Step 4: Test the Fax Line
Call the fax number using a telephone and listen carefully. A working fax line should usually answer with fax tones.
If you call the fax number and get any of the following instead, the issue likely points away from the Xerox device and toward the fax line or service:
- Busy signal.
- Continuous ringing.
- Voicemail greeting.
- No proper fax answer tone.
When to involve the provider: If the fax line gives a busy signal, continues to ring, routes to voicemail, or does not answer with fax tones, contact the fax or phone service provider. That usually means the line is not open and working correctly for fax reception.
Not Sure If It Is the Xerox Device or the Fax Line?
Fax issues can come from the machine, the dialing setup, the phone line, or the service provider. Benchmark can help review the Xerox-side settings and determine whether the next step should be printer support or phone-line support.
Step 5: Send a Small Test Fax
After checking the line and number, send a one-page test fax. A small test is better than a large document because it keeps the test simple and helps isolate whether the machine can establish and complete a fax session.
Internal diagnostic note: If Benchmark’s internal Xerox workflow uses the 0000 test, treat it as an internal fax-card diagnostic only. It may help test the fax card, not the live external fax line. It should not be presented as a universal public fax destination.
Step 6: If the Problem Is Receiving Faxes
If the customer can send but not receive, focus on the receiving side.
Check the following:
- The line is open and not being intercepted by another service.
- The correct fax number is published and being called.
- The device is set to receive faxes properly.
- Voicemail, call routing, or another answering service is not taking the call first.
- The line is dedicated to fax if that is how the site is supposed to operate.
If a caller reaches voicemail instead of fax tones, incoming faxes will fail even if the Xerox machine itself is working normally.
Step 7: If the Device Uses Network or Internet Fax Features
If this Xerox setup depends on network-based faxing or internet fax features, network connectivity also matters.
In that case, check:
- The printer is connected to the network.
- Relevant server, email, or internet-fax settings are still correct.
- Recent network changes did not interrupt the fax workflow.
Treat this as a separate branch from traditional analog fax troubleshooting. A normal phone-line fax problem and a network-based fax problem are not the same issue.
Step 8: Test the Fix
After making corrections, test both directions if possible:
- Send a one-page fax out.
- Confirm that it completes successfully.
- Ask someone to send a test fax in.
- Confirm the machine receives it properly.
If outgoing and incoming tests both work, the issue has likely been resolved.
Common Troubleshooting Notes
- A Xerox printer that prints fine can still have a fax-specific issue.
- A wrong fax number or wrong dialing prefix can look like a machine problem.
- Busy signal, endless ringing, or voicemail usually points to a line or provider issue.
- A one-page test is better than a large fax when troubleshooting.
- The 0000 test from the original notes should be treated as an internal fax-card check, not a universal customer instruction.
- “Check network connection” is only relevant when the fax workflow depends on network or internet-fax features.
When to Contact Benchmark
Contact Benchmark if:
- The machine shows fax-related faults or alerts.
- The fax line appears to be working, but the Xerox device still cannot send or receive.
- The customer needs help reviewing fax setup or dialing settings.
- The fax card or device-side fax hardware may be at fault.
- The internal 0000 fax-card test fails, if that applies in your environment.
When to Contact the Fax or Phone Service Provider
Contact the fax or phone service provider if:
- The fax number does not answer with fax tones.
- The line gives a busy signal repeatedly.
- The line continues to ring instead of answering as a fax.
- The call routes to voicemail.
- There are suspected line or carrier issues.
Frequently Asked Questions About Xerox Fax Problems
Why is my Xerox printer not sending faxes?
A Xerox printer may fail to send faxes because of a bad fax line, incorrect fax number, missing outside-line prefix, outdated address book entry, fax setting problem, or device-side fax hardware issue. Start by checking the number and dialing format, then test the fax line and send a one-page test fax.
Why is my Xerox printer not receiving faxes?
If a Xerox printer can send but not receive faxes, the issue is often with the incoming line, receive settings, call routing, voicemail, or the fax service provider. Call the fax number from a phone and listen for fax tones. If the call goes to voicemail or keeps ringing, the line or service likely needs attention.
How do I test a Xerox fax line?
Call the fax number from a regular phone and listen for fax tones. A working fax line should usually answer with fax tones. A busy signal, continuous ringing, voicemail, or no proper fax tone usually points to a line or service-provider issue.
Can a Xerox printer print normally but still have fax problems?
Yes. Printing, scanning, and faxing rely on different parts of the device and different services. A Xerox printer can print normally while still having a fax-line, fax-setting, or fax-hardware issue.
Should I check the network connection for fax problems?
Only check the network connection if the Xerox fax workflow depends on internet fax, network fax, email-based fax, or another network-related feature. For a traditional phone-line fax setup, the fax line and dialing setup are usually more relevant than the network connection.
What does the 0000 fax test do?
In the Benchmark internal workflow, sending a fax to 0000 may be used as a fax-card diagnostic. It should be treated as an internal test only. It tests the fax card, not the live external fax line, and should not be described as a universal public fax destination.
When should I contact Benchmark for Xerox fax problems?
Contact Benchmark if the Xerox device shows fax-related faults, the fax line appears to work but faxing still fails, the customer needs help reviewing fax setup or dialing settings, or the fax card or device-side fax hardware may be at fault.
Need Help Troubleshooting Xerox Fax Problems?
If the fax line appears to be working but your Xerox device still cannot send or receive faxes, Benchmark can help review the device-side fax settings and determine the next step.
Final Note
The cleanest way to troubleshoot fax problems is to narrow the issue first. Decide whether it is a sending problem, receiving problem, or both. Then check the number, test the line, and confirm whether the issue is with the Xerox machine, the dialing setup, or the fax service itself.
