## 1. What is HP LaserJet Error 68.xx?
HP LaserJet Error **68.xx** is associated with **NVRAM**, a specialized memory component in the printer that stores system configuration settings and printer data even when the device is powered off. This memory is crucial for the printer's firmware to operate correctly. When a malfunction occurs in NVRAM, the printer cannot access its stored configuration properly, resulting in error 68.xx.
This error can appear in various models of HP LaserJet printers, including but not limited to:
* HP LaserJet 4000 series
* HP LaserJet 4050 series
* HP LaserJet 5000 series
* HP LaserJet 8000 series
The “xx” in the error code usually represents additional diagnostic information, like **68.04** or **68.10**, indicating specific issues with memory operations or communication with the NVRAM chip.
## 2. Causes of NVRAM Error
Understanding the causes of Error 68.xx is essential for effective troubleshooting. The common causes include:
1. **Corrupted NVRAM Data:**
If the configuration stored in NVRAM is corrupted, the printer cannot boot properly.
2. **Firmware Issues:**
Outdated or corrupted firmware can conflict with NVRAM operations, triggering the error.
3. **Hardware Failures:**
* Faulty memory DIMM or SIMM cards.
* Damaged NVRAM chips.
* Loose connections on the printer motherboard.
4. **Power Fluctuations:**
Sudden power surges or interruptions can corrupt NVRAM.
5. **Printer Overuse or Age:**
Older LaserJet printers with extended use may experience wear in memory components, leading to failure.
## 3. Identifying Symptoms of Error 68.xx
Before attempting any fixes, it is important to confirm the error is indeed NVRAM-related. Common symptoms include:
* Printer fails to initialize or boot completely.
* Error code **68.xx** appears on the control panel.
* Printer does not respond to print commands.
* Previous print jobs remain stuck in the queue.
* Random freezes or shutdowns during operation.
By confirming these symptoms, users can avoid unnecessary troubleshooting steps and focus on NVRAM-specific solutions.
## 4. Step-by-Step Troubleshooting
Here are the most effective troubleshooting steps for resolving HP LaserJet Error 68.xx:
### 4.1 Restarting the Printer
1. Turn off the printer using the power button.
2. Unplug the printer from the power source.
3. Wait for at least **5–10 minutes** to allow residual energy to dissipate.
4. Plug the printer back in and turn it on.
Sometimes, a simple power cycle can reset NVRAM and resolve minor glitches.
### 4.2 Resetting NVRAM
Resetting NVRAM can clear corrupted configuration data. Follow these steps:
1. Turn off the printer.
2. Press and hold the **Go/Cancel** button (or equivalent depending on your model).
3. While holding the button, turn on the printer.
4. Continue holding the button until all the lights flash once.
5. Release the button and allow the printer to initialize.
⚠️ Note: This may clear custom settings, so you might need to reconfigure the printer settings afterward.
### 4.3 Firmware Update
Updating firmware can fix known issues with memory handling:
1. Visit the **HP Support website**.
2. Enter your printer model and locate the **Firmware Downloads** section.
3. Download the latest firmware version for your printer.
4. Follow the instructions to update firmware via USB or network.
A firmware update ensures compatibility between the printer hardware and NVRAM operations.
### 4.4 Clearing Printer Queue
Sometimes pending jobs in the print queue trigger repeated NVRAM errors:
1. Open the **Devices and Printers** section in Windows.
2. Right-click your HP LaserJet printer and select **See what’s printing**.
3. Cancel all print jobs.
4. Restart the printer and try a test page.
### 4.5 Checking Printer Hardware
* Inspect DIMM or memory cards if your printer model supports upgrades.
* Remove and reseat memory modules to ensure proper connection.
* Inspect the printer motherboard for physical damage or corrosion.
Hardware checks often reveal faults that software fixes cannot resolve.
## 5. Advanced Fixes
If basic troubleshooting does not resolve the error, advanced fixes may be necessary.
### 5.1 Memory Card or DIMM Check
Some HP LaserJet models allow users to upgrade memory:
1. Power off the printer and unplug it.
2. Remove the DIMM or memory card carefully.
3. Reinsert the memory module and ensure it clicks into place.
4. Restart the printer.
If the error persists, the memory module may be defective and need replacement.
### 5.2 Replacing NVRAM Chip
⚠️ Warning: This step is recommended only for experienced technicians.
1. Identify the NVRAM chip on the printer motherboard.
2. Remove the faulty chip carefully.
3. Replace with a compatible NVRAM chip.
4. Reboot the printer and verify operation.
Replacing the NVRAM chip often resolves persistent **68.xx** errors but requires technical skill.
### 5.3 Printer Service Menu Access
Some HP LaserJets allow users to perform **service resets** via the service menu:
1. Turn off the printer.
2. Press a specific combination of buttons (check your printer’s service manual).
3. Access the service menu and select **NVRAM Reset** or **Calibration**.
4. Restart the printer.
Service menu operations often clear residual memory issues that standard resets cannot.
## 6. Preventive Measures
Preventing NVRAM errors is easier than fixing them. Consider these tips:
* **Regular Firmware Updates:** Keep your printer firmware up to date.
* **Stable Power Supply:** Use surge protectors to prevent voltage fluctuations.
* **Avoid Overloading:** Do not exceed the printer’s recommended duty cycle.
* **Scheduled Maintenance:** Clean and inspect the printer periodically.
* **Memory Upgrades:** If upgrading memory, use only HP-certified modules.
Implementing preventive measures can prolong the lifespan of your printer and minimize NVRAM-related errors.
