Hi, The Error "30.01.43" is related to Printer Copy Processor Board Memory Being Full . I would suggest you to consult with Hp Technician to Reseat the Memory Dimm in the copy processor board and restart the printer and check the status .If the error persists CPB memory is the suspected part to be replaced .
Hope this helps .
