    Salve a tutti ho risolto questo problema!,
    ho passato molti giorni alla ricerca di un post in tutti i siti di assistenza che potesse risolvere questo problema ma senza successo poi grazie ad un’altra stampante dello stesso modello sono riuscito a copiare il file firmware originale che non troverete da nessuna parte e vi spiego la soluzione i pochi passaggi
    La soluzione è semplice:
    Dovete smontare il formatter e staccare la compact flash memory che contiene il firmware corrotto
    tramite un lettore di compact flash formattate in file system (fat) la vostra Compact Flash memory da 32mb
    tramite il programma HDDGURU: HDD Raw Copy Tool copiate il file immagine del firmware
    lo so vi chiederete e il file immagine firmware della mia stampante dovè??
    penso di essere l’unico in possesso di questo file x la stampante HP ColorLaserject 5550/5550DN/5550DTN
    se volete il file immagine potete contattarmi su aleyeahweb@gmail.com

    The solution is simple:
