62
HP Printer
Severity: CriticalWhat Does This Error Mean?
Error 62 means the printer has detected a memory error. This can involve the printer's built-in RAM or any extra memory modules installed. The printer cannot operate properly until the memory issue is resolved.
Affected Models
- HP LaserJet 4100 Series
- HP LaserJet 5000 Series
- HP LaserJet 8000 Series
- HP LaserJet 8100 Series
- HP LaserJet 9000 Series
Common Causes
- A RAM DIMM installed in the printer has failed
- A third-party memory module is incompatible with this printer model
- The memory module is not fully seated in its slot
- The printer's built-in memory (soldered to the board) has developed a fault
- An electrostatic discharge damaged the memory module
How to Fix It
-
Power off the printer and unplug it from the wall. Wait 60 seconds.
Always unplug before handling any internal components to avoid electric shock.
-
Locate the memory DIMM slots on the printer. On most HP LaserJets, these are behind a small panel on the side.
Check your printer's manual for the exact location of the memory slots.
-
Remove any extra memory modules that were added by you or a previous owner.
Leave only the factory-installed memory and see if the printer starts normally.
-
If you removed a module, clean the contacts with a dry lint-free cloth and reseat it firmly.
Press down on both sides of the module until it clicks into place.
-
Plug the printer back in and power it on. If error 62 clears, the removed module was faulty.
Replace it with an HP-approved memory module for your specific model.
When to Call a Professional
If removing extra memory modules does not clear error 62, the onboard memory has failed. This usually means replacing the formatter board. Contact HP support or a certified technician — formatter boards cost $100 to $350.
Frequently Asked Questions
Can I use any DDR RAM in my HP printer?
No. HP printers use specific types of memory modules, not standard computer RAM. Using the wrong type will cause errors like error 62. Always buy HP-approved printer memory or check HP's compatibility list before purchasing.
My printer never had extra memory added, but I still get error 62. Why?
In that case, the built-in memory on the formatter board has likely failed. This is less common but does happen, especially in older printers. A technician will need to replace the formatter board.
How do I know if my printer's memory is failing versus just a loose connection?
Remove and reseat the memory module first — a loose connection is a quick, free fix. If reseating does not help, the module itself is likely bad. Try replacing it with a known-good HP-compatible module to confirm.
