## **1. What is HP Printer Error 79?**

Error 79 on HP printers is typically a **firmware or network-related error**. It occurs when the printer experiences an internal communication failure, a bad print job, or a corrupted firmware file.

When Error 79 appears, your printer might show:

* “**79 Service Error**”
* “**79 Error Turn Off then On**”
* “**79.00FE Error**”

This usually causes your printer to freeze or restart repeatedly, and it won’t print until the issue is resolved.

## **2. Common Causes of HP Printer Error 79**

To fix Error 79 effectively, it’s important to understand what triggers it. The most common reasons include:

### **2.1 Corrupted Print Jobs**

A damaged or incompatible print file can cause your HP printer to crash and display Error 79. This often happens when printing from PDF files or documents with unsupported fonts.

### **2.2 Outdated Printer Firmware**

If your HP printer firmware is outdated, it may not be compatible with newer devices or operating systems, leading to system errors.

### **2.3 Faulty Network Communication**

If the printer is connected to a network, bad IP configurations, conflicting devices, or Wi-Fi instability can trigger error messages like Error 79.

### **2.4 Faulty Hardware or DIMM Modules**

For certain HP LaserJet models, defective memory modules (DIMMs) or accessories attached to the printer may cause internal conflicts.

### **2.5 Incompatible Third-Party Print Drivers**

Sometimes, third-party printer drivers or software (especially from Windows updates) can cause communication issues between the computer and the printer.

### **2.6 Overloaded Print Queue**

If multiple print jobs are stuck or corrupted in the queue, the printer might display a 79 Service Error while trying to process them.

## **3. Symptoms of HP Printer Error 79**

Before we dive into the solutions, let’s identify the common symptoms of this error:

* The printer’s **display shows “Error 79”** or **“79 Service Error”**.
