Hi  @SaK88 
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand that your HP PageWide Pro 477dw Multifunction Printer is displaying the Blue Screen error code B33E107C.Don't worry  I’ll try looking into this and try helping you with this .
 

To better understand the situation, could you kindly confirm is the printer displaying the error immediately after power-on, or does it appear during printing, copying, or scanning?
 

The B33E107C blue screen error generally indicates that the printer has encountered an internal firmware or system-level fault.

 This can sometimes occur due to corrupted firmware data, an incomplete startup sequence, or a hardware component that is not initializing correctly. 

kindly try these steps:

1. Turn off the printer and disconnect the power cord from the rear of the printer.
2. Wait for about 60 seconds.
3. Plug the power cord directly into a wall outlet, avoiding surge protectors or power strips if possible.
4. Power the printer back on and check whether the error returns.
5. If the printer reaches the Home screen, try performing a partial reset from the printer menus if available.
6. Ensure the printer firmware is up to date if you are able to access the printer settings.

Performing a power reset and checking for firmware updates are useful first steps because they help eliminate temporary firmware-related conditions. If the error persists even after a power reset and appears immediately during startup, further diagnostics may be required to determine whether the issue is related to the printer's internal hardware or firmware.

I hope this helps.
