Printer power/error message

HP Officejet 4650

My printer is reading ERROR CODE 0X0005FBB6 LIB_MATH C . Not sure if the code is zeros or the letter "O" but think they are zeros. The lights next to the printer screen are flashing (the home, help and back buttons). The power light is on. 


This happened twice. When I first tried to use the printer it would not turn on. U read every article, watched every video and used the virtual assistant. Reset the power more than once. There is no indicator light that I can find on this model. Tried different cords and outlets. Now that the power light is on and screen is lit up, this happens.

Printer power/error message

@Lyxi, Welcome to the HP Support Community!


Are you able to bypass this error and access the home screen on the printer?

If you can access the home screen, we may try resetting the printer to its factory settings.


For now, let us try these steps:


Reset the printer (Skip if tried)

  1. With the printer turned on, disconnect the power cord from the rear of the printer.
  2. Wait at least 60 seconds.
  3. Reconnect the power cord to the rear of the printer.
  4. Turn ON the printer, if it does not automatically turn on.
  5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.
