The HP OfficeJet Pro 7740 displays a blue screen with error code B80FC102 and fail to complete startup. The error is associated with a firmware crash or corrupted/failed firmware state.
Firmware installation that did not complete correctly.
Corrupted firmware or printer system data.
Temporary printer memory/state corruption.
A configuration problem following a firmware update.
Less commonly, an underlying printer hardware failure if firmware recovery does not resolve the issue.
Troubleshooting steps
1: Record the Error
Note the complete error displayed on the printer.
Confirm that the code is B80FC102.
If possible, take a photograph of the blue screen.
Note whether the problem started:
Immediately after a firmware update.
After a power interruption.
After changing network settings.
After installing or updating printer software.
If the printer provides diagnostic/history information, record the available information before resetting the printer.
This information helps determine whether the failure is associated with firmware, configuration, or hardware.
2: Perform a Full Power Reset
Turn off the printer using the Power button.
If the printer does not turn off normally, disconnect the power cord from the printer.
Disconnect the power cord from the electrical outlet.
Disconnect USB/Ethernet cables and other cables from the printer.
Wait at least 60 seconds.
Connect the printer directly to a known-good wall outlet.
Do not use a surge protector, extension cord, or UPS during this test.
Turn on the printer.
Allow the printer several minutes to complete initialization.
A complete power drain can clear temporary memory/state corruption and allows the printer's firmware to initialize from a clean state.
3: Check Whether the Printer Can Reach the Home Screen
After powering on, determine whether the printer:
Reaches the normal Home screen.
Remains permanently on the blue error screen.
Starts normally but crashes after several seconds/minutes.
Allows access to Setup or Printer Maintenance.
If the Home screen is available
Continue with the firmware and reset procedures below.
If the printer remains stuck on B80FC102
Skip to 5 – Firmware Recovery/Reinstallation.
4: Restore Printer Defaults
If the printer successfully reaches the control-panel menus:
Open Setup.
Look for the printer's Restore Defaults / Restore Factory Defaults option.
Follow the on-screen instructions.
Allow the printer to restart.
Reconfigure Wi-Fi/network settings if necessary.
Test the printer.
A corrupted configuration or invalid stored setting can sometimes cause a firmware crash. Restoring defaults removes user configuration and returns the printer to a clean configuration state.
Note: Restoring defaults may remove saved network settings and other customized printer settings.
5: Reinstall or Update the Printer Firmware
This is the primary recovery step when B80FC102 persists, particularly when the issue began immediately after a firmware update.
On a computer, open the official HP OfficeJet Pro 7740 support page.
Select Software and Drivers.
Select the appropriate operating system.
Locate the available firmware for the OfficeJet Pro 7740.
Download the firmware package from HP.
Close unnecessary applications on the computer.
Connect the printer to the computer using the connection supported by the firmware utility, such as USB or network.
Run the HP firmware update utility.
Select the OfficeJet Pro 7740 when prompted.
Follow the on-screen instructions to reinstall/update the firmware.
Do not turn off the printer or disconnect its power while the firmware is being installed.
Wait until the firmware process finishes and the printer restarts.
Check whether B80FC102 has cleared.
If the firmware image or firmware installation state is corrupted, reinstalling the correct firmware can restore the printer's operating system.
6: If the Printer Cannot Boot Normally
If the printer remains on the blue B80FC102 screen:
Perform the 60-second power reset again.
Connect the printer directly to a wall outlet.
Disconnect unnecessary USB/network cables.
Restart the printer.
From a Windows computer, download the appropriate HP firmware update utility for the OfficeJet Pro 7740.
Connect the printer directly to the computer where supported.
Run the firmware utility.
Follow the utility's instructions for detecting and updating the printer.
Allow the firmware process to complete without interrupting power.
If the firmware utility cannot detect the printer or cannot complete the recovery, continue to the hardware/service assessment.
7: Test the Printer After Firmware Recovery
After the firmware update/reinstallation:
Restart the printer.
Verify that the normal Home screen appears.
Check whether the printer remains powered on without displaying B80FC102.
Print an internal printer report or test page.
Test copying directly from the printer.
Test scanning.
Reconnect the printer to Wi-Fi if necessary.
Add the printer back to the HP app/operating system.
Send a test print from the computer.
Testing directly from the printer first helps determine whether the problem has been resolved at the printer level before introducing computer or network variables.
8: Determine Whether the Problem Is Hardware-Related
If all of the following are true:
The printer continues displaying B80FC102.
A full power reset does not resolve the problem.
The printer cannot complete firmware recovery.
The correct firmware has been successfully attempted.
Restoring defaults is not possible or does not help.
Then the issue may require printer hardware/service evaluation.
