The printer displays Error Code C9C60006 on a blue screen, preventing normal printer operation and requiring troubleshooting to restore printer functionality.
Troubleshooting Steps
1: Perform a Power Reset
Turn off the printer.
Disconnect the power cord from the rear of the printer.
Wait at least 60 seconds.
Reconnect the power cord directly to a wall outlet.
Turn the printer back on.
Check whether the error code reappears.
2: Check for Printer Firmware Updates
Outdated firmware can cause unexpected system errors.
Access the printer's Embedded Web Server (EWS) or HP support page.
Verify that the printer is running the latest firmware version available for the LaserJet Pro MFP 4101 series.
Install any available firmware updates.
Restart the printer after the update completes.
3: Restore Factory Defaults
If the printer boots successfully:
Open the printer control panel menus.
Navigate to Settings or Service.
Select Restore Factory Settings.
Allow the printer to restart.
Reconfigure network and printer settings after the reset.
4: Verify Hardware Connections
Disconnect USB, Ethernet, and any external devices connected to the printer.
Restart the printer using only the power cable connected.
Observe whether the error returns.
Reconnect devices one at a time to identify a possible communication issue.
5: Run HP Diagnostic Tools
Use the troubleshooting and diagnostic resources available for the HP LaserJet Pro MFP 4101 series.
Visit the product support page.
Open Tools & Diagnostics.
Run any available printer diagnostics.
Apply any recommended fixes.
6: Check for Hardware Failure
If the printer continually displays C9C60006 immediately after startup and the error persists after:
Power reset
Firmware update
Factory reset
The issue may be related to an internal printer component requiring service.
