HP Error 58.04 — What It Means & How to Fix It
Updated July 2026 · Independent PrinterCare USA support guide
Error 58.04 is one of the more frustrating HP faults because it often appears suddenly and blocks all printing until resolved. This error specifically indicates that the printer cannot read temperature data from the environmental thermistor, or that the power delivery to critical components is unstable—both situations that require immediate attention to prevent hardware damage.
The good news is that most cases resolve with basic troubleshooting, and the issue rarely spreads to other printer systems. However, if simple fixes do not clear the error within 24 hours, professional service becomes necessary because internal component replacement may be required.
How to fix it — step by step
- Perform a complete power cycle. Turn off the printer using the power button, then unplug the power cable from the back of the printer and the wall outlet. Wait for exactly two full minutes while the printer sits unplugged—this allows all capacitors in the power supply to fully discharge. Plug the printer back in and power it on, then observe whether the error code returns.
- Check the printer's intake vents and internal sensors. Open the printer access panels according to your model's manual and visually inspect the thermistor sensor, which typically appears as a small cylindrical component near the fuser or paper path. Use a clean, dry, lint-free cloth to gently wipe away any dust or paper debris from the sensor and surrounding vents. Do not apply liquid or excessive pressure, as the sensor is delicate.
- Reseat all internal cables and connectors. While the printer is unplugged and cool, locate the cable that connects the thermistor to the main logic board—this is usually a small white or gray ribbon connector near the front of the printer. Gently disconnect this cable by pressing the small retention clip on the connector, then wait five seconds and reconnect it firmly until you feel a clear click. Repeat this process for the power supply connector and any other visible ribbon cables.
- Reset the printer to factory settings. Access the printer's web interface by typing the printer's IP address into a browser on your Windows or Mac computer (you can find the IP on the printer's network settings page). Navigate to Settings, then Device, then Restore Default Settings, and confirm the reset. Allow the printer to restart fully, which may take three to five minutes.
- Update or reinstall the printer firmware. Visit the HP support website on your computer and enter your exact printer model number. Download the latest firmware file to your computer, then use the printer's web interface to navigate to Administration, then Firmware Update, and upload the downloaded file. Do not power off the printer during this process, as it can cause permanent damage to the firmware.
- Test with a fresh print job and check error logs. Send a test print job from your computer to the printer and note whether error 58.04 appears again. If it does, access the printer's error log through the web interface under Reports or Logs, and take a photograph of any additional error codes listed. These codes will help a technician diagnose whether the issue is truly the thermistor, the power supply, or a communication fault.
- Arrange professional diagnostics or service. If the error persists after all steps above, contact an authorized HP service center or a qualified independent repair technician in your area. Many offer remote diagnostic services for around forty-nine dollars that can pinpoint whether the thermistor, power board, or motherboard requires replacement. Continuing to use the printer with this error may cause additional internal damage.

Frequently asked questions
Does error 58.04 mean my printer will stop working completely?
Not immediately, but the printer will refuse all print jobs until the error is resolved. The thermistor error is a safety feature that prevents the printer from overheating or delivering incorrect power to components. If you ignore the error for extended periods, the underlying power or sensor fault can damage the fuser, logic board, or paper path components.
Can I fix error 58.04 by just replacing the thermistor myself?
Replacement is possible if you are comfortable with electronic assembly, but the thermistor is soldered or closely integrated into the paper path on most HP models, making it a moderately difficult repair. For most users, professional replacement is safer because technicians have the proper tools, replacement parts, and warranty coverage. A service call typically costs between eighty dollars and one hundred thirty dollars depending on your location and model.
Why does my printer keep showing error 58.04 even after I power cycled it?
A persistent error after power cycling usually indicates that the thermistor itself has failed, the cable connecting it is damaged, or the power supply board is delivering unstable voltage. These are hardware faults that cannot be fixed by software updates or cable reseating alone. At this point, you should contact a repair service because the component itself requires replacement.
Is error 58.04 covered under HP's warranty?
Most HP printers include a one-year limited warranty that covers hardware defects like sensor failures, provided the printer has not been damaged by user error, spills, or power surges. Check your warranty documentation or contact HP support with your serial number to confirm coverage. If your warranty has expired, you may qualify for extended service plans or third-party repair options.
