Xerox Error 010-397 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The 010-397 error on Xerox printers is one of the most common hardware failures we see in the field, and it means the fuser unit that melts toner onto paper has either overheated, lost its thermal sensor connection, or reached end of life. This error appears because your printer's firmware detected a fuser temperature reading outside safe operating range, which triggers an automatic shutdown to prevent damage to the machine and fire hazard.
While a fuser replacement is often the final answer, several diagnostic steps can save you money before you call a technician or purchase parts. We recommend working through these steps systematically because sometimes the error is caused by a loose connector or a simple firmware state issue rather than actual hardware failure.
How to fix it — step by step
- Power cycle the printer completely. Turn off the printer using the power button on the front panel, then unplug the power cable from the wall outlet. Wait exactly two minutes—this allows capacitors to fully discharge and resets the printer's error state. Plug the printer back in, power it on, and attempt a test print to see if the error has cleared.
- Check for paper jams and debris in the fuser area. Open the access door to the fuser unit according to your model's manual (usually located behind the front cover or rear access panel). Visually inspect for torn paper, toner dust buildup, or foreign objects inside the fuser chamber. Use a flashlight to get a clear view, and never touch the fuser rollers with your bare hands as skin oils will damage them.
- Verify the fuser connector is fully seated. Locate the fuser unit's ribbon cable connector on the main logic board—this is typically a white or gray plastic connector with a locking tab. Gently but firmly push the connector straight in until you hear or feel it click into place. Sometimes vibration during shipping or normal operation can partially dislodge this connector, triggering false error codes.
- Clean the fuser thermistor contact points. The thermistor is a small temperature sensor (usually located on the fuser assembly) that communicates fuser temperature to the printer's main board. Using a cotton swab barely dampened with isopropyl alcohol, gently wipe the gold or silver contact points on both the sensor and its connector to remove oxidation. Allow thirty seconds for alcohol to evaporate before reassembling.
- Run a network diagnostic if your model supports it. Access the printer's embedded web server by typing your printer's IP address into a web browser on your Windows 11 or Mac computer (find the IP address on the printer's status page or network settings menu). Navigate to the Diagnostics or Device Information section and look for fuser temperature readings—values should fall within the normal operating range specified in your model documentation.
- Update the printer firmware to the latest version. Visit the Xerox support website on your computer, search for your specific printer model number, and download the latest firmware release. Follow the firmware update instructions provided, which typically involve uploading the file through the embedded web server or using Xerox's software utility. Firmware updates sometimes correct sensor reading errors that cause false 010-397 codes.
- Consult remote diagnostics or prepare for fuser replacement. If the error persists after these steps, your fuser unit likely requires replacement. You can pay approximately $49 for a remote technician to confirm the diagnosis via TeamViewer or similar software before purchasing a $250 to $400 replacement fuser assembly. Order the correct fuser kit for your specific model (for example, the fuser for a Xerox VersaLink C405 differs from a C7025), and follow the installation manual carefully or have a technician install it.

Frequently asked questions
Can I keep using my printer with error 010-397, or will it damage the machine?
You should not continue printing once this error appears because the fuser either has lost temperature regulation or failed completely. Printing with a faulty fuser can cause toner to not adhere properly to paper, create fire hazards from uncontrolled heat, or damage the fuser assembly further. The error code exists specifically to protect your equipment and your safety.
How long does a fuser unit usually last before it fails?
Most Xerox fuser units are rated for between 200,000 and 400,000 pages depending on the printer model, though this varies based on usage patterns and environmental factors. High-volume printing, excessive heat or humidity, and printing with incompatible toner can all accelerate fuser wear. You can typically check your page count in the printer's web interface or settings menu to estimate remaining fuser life.
Should I buy a new fuser from Xerox or from a third-party supplier?
Genuine Xerox fuser units come with a warranty and are guaranteed to work with your specific machine, though they cost more than compatible aftermarket units. Third-party fuser kits are cheaper but may have quality inconsistencies or come without support. We recommend genuine Xerox parts for mission-critical business printers, but compatible units work adequately for home office use if budget is your primary concern.
What is the difference between error 010-397 and other fuser-related errors like 010-396?
Error 010-397 specifically indicates a fuser temperature sensor failure or overtemperature condition, while 010-396 typically refers to a fuser lamp failure (in laser models) or different temperature issue. The diagnostics steps are similar, but the components that need replacement differ. Always check your specific model's error code documentation to confirm which part is failing before ordering replacement parts.
