HP Printer Error Code 68 — What It Means & How to Fix It

What Does This Error Mean?

Error 68 means the printer failed to save data to its permanent storage (called NVRAM). NVRAM stores your printer's settings — things like tray configuration and print counts. The printer can usually still print, but settings may not be saved after a power cycle.

Affected Models

HP LaserJet 4100 Series
HP LaserJet 4200 Series
HP LaserJet 4300 Series
HP LaserJet 4250 Series
HP LaserJet 9000 Series

Common Causes

The NVRAM (non-volatile memory) chip on the formatter board is failing
The printer's power was interrupted during a settings save operation
The formatter board has a hardware fault affecting the storage circuit
Firmware corruption has damaged the data structures used to write settings
A recent firmware update introduced a bug that affects NVRAM writes

How to Fix It

Power the printer off and on. Press OK if prompted to continue. The printer may still print normally.

Error 68 with a 'continue' option is sometimes just a warning, not a full failure.
Check if the printer still prints correctly. If it does, note which settings are lost after a power cycle.

If settings are not retained, the NVRAM has failed or is failing.
Perform a cold reset on the printer to clear stored settings and start fresh.

On most HP LaserJets, hold the Go button while turning on the printer. Check your model's manual for exact steps.
Check HP's support site for a firmware update. A buggy firmware version can sometimes cause NVRAM write errors.

Download the update and install it per the instructions on HP's site.
If the error persists after a firmware update and cold reset, contact HP support or a repair technician.

Persistent NVRAM errors indicate a hardware failure that requires board replacement.

When to Call a Professional

NVRAM failure usually means the formatter board needs to be replaced. This is a job for a certified HP technician. Formatter boards typically cost $100 to $350 depending on the printer model.

Frequently Asked Questions

Can I keep using the printer if I get error 68?

Often yes, if the printer offers a 'Press OK to continue' prompt. The printer will still print, but you may need to re-enter settings after each power cycle. Monitor the situation — if it gets worse, plan for a repair soon.

What does NVRAM actually store on a printer?

NVRAM stores configuration settings that need to survive power being turned off. This includes paper tray sizes, print density, jam count, page count, and network settings. Losing NVRAM data means the printer forgets its settings every time it is powered off.

Is error 68 common on older HP LaserJets?

Yes, it becomes more common as printers age. NVRAM chips have a limited number of write cycles and can wear out over many years. High-volume office printers tend to see this error sooner than low-volume home printers.
