I was using the 5400c when it went blank, like the power cord was unplugged. I check all connection and they are good. Does this machine have a fuse or reset? I have not been able to find it. I would really appreciate any suggestions or where I may send it for repairs.
Thanks a million.
I have a similar scanner, scanjet 5470c which is using the same power supply as 5400c and 5490c 2 weeks ago the scanner stopped working, yesterday i checked the scanner and found out that there was no power (12V) the power module (black box) going into the 220V is a plastic box without service possibility. I took a screwdriver and a hammer to open the box. Inside the box i found a lot of electronics and yes a Fuse aswell. I did not have spare fuses, so like all bad boys i replaced the fuse with a wire, and guess what? .. yep I blew several main fuses in the house and now have a burned-out power supply. the power module is still available at the HP Parts Store the part number is C8517-84201 i see a list price of 23 EUR
Before a buy a new power module I will first test the scanner with a spare 12VDC and see if he still works.
I have had the power go out on my HP 5400c scanner, It was the power supply. What I had found out or was told by the parts person that sold ne a new one was if you leave them pluged in the will eventually burn out. It took about 3 yr. to o that before I had to replace it.
My scanjet HP 5400c was working before and was not in use for sometime. Then I pressed the on buttom and there was no power light at the machine. With no apparent power to the unit I check the power cord voltage and no response in the test meter. Is the power supply cord at fault or something internally went wrong? Is there a reset button or fuse to change or power supply transforme problem? Please help.

If you actually need the entire power adapter, that's a bit more complicated. There are a lot of online vendors, but I'd need to know your location and "risk tolerance" to give you the best purchasing options.
I had similar problem with my UMAX scanner on numerousoccasions. I now have this pg earmarked for quick reference! may help I don't know for sure but it is an easy test and if it works your good to go!
It is important that you connect the scanner's power and USB cables in the following order:
1. Plug the power adapter cord into the scanner and into an outlet. The scanner's power will then be on.
2. Connect the USB cable to the USB port on the
back or front of the computer.
NOTE: If you unplug the scanner's power ,you must also disconnect the USB cable from the computer. To resume use of the scanner, remove the power card, the the USB cable.
Sounds like a lot but the order is essential!
If it works, High lite Do unplug USB/unplug cable back of scanner/and plug cable back of scanner then USB!
Good Luck Hope this helps!
Unplug the power cord from the All-In-One as well as the power outlet when there is still power in the All-In-One. and wait for atleast 1Min
Plug the power cord directly to a wall outlet without surg protector. (if possible connect it to a different power outlet) Before connecting the power cord to the All-In-One press and hold the # and no 6 button and then insert the power cord, do not release the keys until you see a message a reset (if the screen goes blank then release the keys and turn the power on)
