Common Causes

A firmware update was interrupted midway through and left the printer in an error state
The printer experienced a power surge or unexpected shutdown during operation
The printer's internal memory has encountered a fault that needs a hardware reset
A corrupt print job was sent to the printer and crashed the internal processor
The printer has been in use for a very long time and accumulated errors in its memory

How to Fix It

Turn the printer off using the power button. Then unplug the power cable directly from the back of the printer. Wait a full 60 seconds — do not skip this wait.

A full power-down with a 60-second wait is essential — shorter waits may not fully reset internal memory.
Plug the power cable back in while holding the Resume (or checkmark) button on the printer's control panel. Keep holding the button until the printer starts making sounds and the display lights up.

This activates a forced reset sequence on many HP Laserjet Pro models.
If the button-hold method does not work, try a full factory reset from the printer's menu. Go to Setup > Service > Restore Defaults or Setup > Resets > Restore Factory Settings.

The exact menu path varies by model — check your printer's manual for the reset procedure.
Update the printer's firmware. Visit hp.com/support, enter your model number, go to Firmware, and download the latest version. Install it by USB or by connecting to your wireless network.

An outdated or partially corrupted firmware is a known cause of OXC4EB827F.
If the printer is stuck in the error loop and will not respond to any button presses, try a cold reset. Unplug the printer, hold the Go or OK button, plug the power back in while still holding the button, and keep holding until the Attention light blinks.

A cold reset bypasses the normal boot sequence and forces the printer to reload its firmware from scratch.

When to Call a Professional

If the reset procedure does not clear the error after two attempts, contact HP Support. HP offers free support for printers under warranty and paid out-of-warranty support. Some Laserjet Pro models can have firmware recovered by HP's remote technicians.

Frequently Asked Questions

Will a factory reset delete all my printer settings?

Yes — a factory reset wipes all stored settings including Wi-Fi passwords, custom paper settings, and admin passwords. You will need to set up your network connection again after the reset. For network setup, use the HP Smart app on your phone — it makes reconnecting quick and easy.

Could a bad print job cause this error?

Yes — a corrupted or very large print job can crash the printer's internal processor and trigger this error. After clearing the error, check your print queue on your computer and delete all pending print jobs before trying to print again.

My printer shows this error right after a firmware update. What should I do?

This is a known issue on some HP Laserjet Pro models after a firmware update. Try the power cycle and cold reset steps first. If the printer is still stuck, contact HP Support — they have a procedure to re-flash the firmware using a USB drive.
