61
HP Printer
Severity: CriticalWhat Does This Error Mean?
Error 61 means the printer detected a problem with its formatter board. The formatter board is the brain of the printer — it processes print jobs and controls all functions. This error usually requires professional attention.
Affected Models
- HP LaserJet 4100 Series
- HP LaserJet 4000 Series
- HP LaserJet 5000 Series
- HP LaserJet 8000 Series
- HP LaserJet 8100 Series
Common Causes
- The formatter board (main logic board) has failed or is malfunctioning
- The firmware on the formatter board is corrupted
- A memory DIMM installed in the formatter slot is faulty or incompatible
- The formatter board is loose and not making proper contact with its connector
- A power surge or static discharge damaged the formatter board
How to Fix It
-
Turn the printer completely off and unplug it from power. Wait 60 seconds before proceeding.
This discharges any residual electricity that could prevent a clean reboot.
-
Plug the printer back in and power it on. Watch to see if the error appears immediately or after a moment.
If it appears immediately, the formatter board itself is likely the cause.
-
If your printer has user-accessible memory slots, remove any extra RAM DIMMs you may have added.
A faulty or incompatible memory module can sometimes trigger formatter errors.
-
Check HP's support site to see if there is a firmware update available for your printer model.
A corrupted firmware update can cause error 61. HP sometimes releases fix firmware for this issue.
-
If none of the above works, contact HP support or a certified printer repair service.
Formatter board replacement is the most common repair for persistent error 61.
When to Call a Professional
Error 61 almost always requires a technician. Formatter boards are expensive — typically $100 to $400 depending on the model. A technician may also attempt to reflash the firmware before replacing the board.
Frequently Asked Questions
Can error 61 be caused by a bad firmware update?
Yes. If a firmware update was interrupted or corrupted, it can damage the formatter firmware. Some HP models allow you to roll back or reinstall firmware via a USB drive. Check HP's support page for your specific model for instructions.
Is it worth repairing a printer that shows error 61?
It depends on the printer's age and replacement cost. If the printer is under warranty, HP will repair or replace it. For an older printer, buying a new one may cost less than a formatter board replacement.
Can I fix error 61 myself?
If it is caused by a bad memory module, yes — just remove the extra RAM. If the formatter board itself has failed, no — that requires a technician. Do not attempt to open or reseat the formatter board yourself unless you are comfortable with electronics.
