What This Error Means

HP Error 68 indicates a problem with the printer's Non-Volatile Random Access Memory (NVRAM) or other persistent storage, which stores critical settings and configuration data.

Detailed Explanation

Error 68 on HP printers typically signifies an issue with the printer's NVRAM (Non-Volatile Random Access Memory) or its persistent storage. This memory is crucial as it holds vital configuration data, such as network settings, paper tray configurations, print counts, and other user-defined preferences, even when the printer is powered off. When this error appears, it suggests that the printer is either unable to read from, write to, or properly initialize this memory area, leading to a state where it cannot operate correctly. The causes for an NVRAM error can range from minor software glitches or corrupted firmware to more serious hardware failures. A sudden power surge or an improper shutdown can sometimes corrupt the data stored in the NVRAM. Less frequently, the NVRAM chip itself or the associated circuitry on the formatter board might be failing. While often a software-related issue that can be resolved with a reset, persistent Error 68 warnings often point towards a hardware component that needs professional attention.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Perform a hard reset: Turn off the printer, unplug it from the wall outlet, wait at least 60 seconds, then plug it back in and turn it on.
2
Check for firmware updates: Visit the HP support website for your specific printer model and download/install the latest firmware if available. Follow the instructions carefully.
3
Restore factory defaults (NVRAM initialization): This will erase all custom settings. The exact steps vary by model, but usually involve holding down a specific button combination during power-on (e.g., 'Go' button, 'Cancel' button, or navigating through service menus). Consult your printer's manual for the precise NVRAM reset procedure.
4
Isolate power issues: Plug the printer directly into a wall outlet, bypassing any surge protectors or power strips, to rule out external power supply problems.
5
Remove and reinsert accessories: If applicable, power down the printer and carefully remove and reinsert any installed memory modules, network cards, or other accessories to ensure they are seated correctly.
6
Check for internal obstructions: While unlikely for this error, a severe internal jam or foreign object could theoretically interfere with system initialization. Perform a thorough visual inspection of all accessible paper paths.
7
Try a different power cable: A faulty power cable, though rare, could contribute to intermittent power delivery affecting memory integrity.

When to Call a Specialist

If you have performed all the DIY troubleshooting steps, including hard resets, firmware updates, and NVRAM initialization, and the Error 68 persists, it's highly indicative of a hardware failure. This typically points to a problem with the printer's formatter board, where the NVRAM chip is located, or another critical electronic component. At this point, specialized diagnostic tools and replacement parts are usually required, making professional service necessary. Continuing to try to force the printer to work could potentially cause further damage.
