Question about HP Scanjet 4070 Flatbed Scanner
I have an HP 4070 ... doesn't want to power up transformer OK
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.

Review the fuse in the internal printed circuit board.
