Power requirement per HP specs is 12VDC @ 575mA 6.9w. My scanner and power supply shows 12 VDC @ 1250ma.Over double the power going in that required. No wonder the fuse blows and you have to buy a new scanner because you can't identify or get a replacement fuse. I would suggest you confront HP and have them supply you with a new scanner.

Mine has the same problem. The fuse is blown. However, I do not know the rating of it. I am looking, but no luck.

I have a older puter with vistas OS and my scanner is not recognized when i connect it?


Hi dtvalascho
Your device will run under XP but no more under Vista or Windows XP . HP doesn't support this unit anymore .
Installing a Virtual version of XP on your system or genuine version on a secundary are the only options .
Best regards ,
