The HP LaserJet 79.00FE error is one of the most common firmware-related issues affecting HP LaserJet printers. It usually appears unexpectedly and can prevent your printer from processing print jobs or reaching the Ready state. In many cases, the error is caused by a corrupted print job, outdated firmware, incompatible printer drivers, or network communication problems rather than a hardware failure.

This guide explains the causes of the HP LaserJet 79.00FE error and provides practical, step-by-step troubleshooting methods to help you get your printer working again.

Common Causes of HP LaserJet 79.00FE Error

Firmware Problems

Outdated or corrupted firmware is one of the leading reasons for this error. Firmware controls how the printer communicates with your computer and processes print jobs.

Corrupted Print Jobs

A damaged or unsupported document can cause the printer to freeze and display the 79.00FE error.

Driver Compatibility Issues

Older or incompatible printer drivers may send incorrect commands that trigger firmware errors.

Network Communication Problems

Network interruptions, unstable Wi-Fi connections, or incorrect IP settings may cause communication failures between the printer and connected devices.

Faulty Printer Accessories

In rare situations, optional accessories such as memory modules or third-party network cards can cause firmware conflicts.

How to Fix HP LaserJet 79.00FE Error

Restart the printer.

Turn off the printer and disconnect the power cable for about one minute. Reconnect the power cable and restart the printer. A simple restart often clears temporary firmware glitches.

Disconnect Network or USB Cable

Disconnect the printer from your computer or network before restarting it. If the printer starts normally, the problem may be related to a corrupted print job or network communication.

Clear the print queue.

Delete all pending print jobs from the computer.

For Windows:

• Open Printers & Scanners
• Select your HP printer
• Open the print queue
• Cancel all documents

After clearing the queue, reconnect the printer and test it again.

Print a Test Page

Print a simple test page to confirm that the printer is functioning correctly before sending larger documents.

Update HP LaserJet firmware.

Why Firmware Updates Matter

Firmware updates improve printer stability, fix software bugs, enhance security, and resolve known error codes such as 79.00FE.

Install the Latest Firmware

Download and install the latest firmware that matches your HP LaserJet printer model. Restart the printer after the update is complete.

Reinstall the printer driver.

Remove the Existing Driver

Uninstall the current printer driver from your computer.

Install the Latest Driver

Download and install the latest compatible driver for your operating system. Restart your computer after installation.

Verify Printer Communication

Print another test page to ensure the driver communicates correctly with the printer.

Check Network Configuration

Verify Network Connectivity

Ensure the printer is connected to the same network as your computer.

Assign a Static IP Address

Using a static IP address helps prevent connection issues that may contribute to recurring firmware errors.

Restart Network Equipment

Restart your router or network switch if communication problems continue.

Remove Faulty Print Jobs

Identify the Problem Document

If the error occurs after printing a specific file, the document may contain unsupported fonts, damaged graphics, or corrupted formatting.

Print Smaller Documents

Try printing a different file or reduce document complexity to identify whether the issue is document-specific.

Perform a Cold Reset

When to Use a Cold Reset

If the error persists after basic troubleshooting, restoring factory settings may resolve configuration-related issues.

Important Considerations

A cold reset removes custom settings, including:

• Network configuration
• Stored preferences
• Custom printer settings

Reconfigure the printer after the reset is complete.

Prevent HP LaserJet 79.00FE Errors

Keep Firmware Updated

Install firmware updates regularly to improve printer reliability.

Use Genuine Printer Drivers

Always install drivers that are compatible with your operating system and printer model.

Maintain a Stable Network

Reliable network communication reduces firmware interruptions.

Clear Stuck Print Jobs

Remove failed print jobs before restarting the printer to avoid repeated errors.

Restart the Printer Periodically

Occasional restarts help clear temporary memory and firmware processes.
