Loss of power

You can probably get this from HP. See http://h20141.www2.hp.com/Hpparts/Search_Multi_Product.aspx?mscssid=42F39AE6AD6B4EFBBC921EC42BADCDE3&SearchCriteria=Scanjet~5400C and select your model. There are 4 versions of the ScanJet 5400C listed. Then select power module in the drop down menu and click on the arrow; power cords are listed separately. Alternatively, click on the arrow for show all parts. The listings are clearly labeled for the country electrical system with which a given part is compatible.

I hope this helps.

If it's just the power cord you need, monoprice.com has excellent prices. Here's the cord listing:

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.

For that scanner you will need AC power module, in this link you can see power modules for that scanner:

Check the Connections
in Most of the cases the Power Cable might be the Problem
Check with the Different power cable - from some other equipment

Did the power cord is connected properly, if so check the fuse

I had similar problem with my UMAX scanner on numerous occasions. 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!

following this link i've found resetting instructions for this scanner:


1.. Disconnect the USB cable and the power cable from the
scanner. Make sure the power cable is still connected to the
power source.
2.. Press the Scan and Email buttons at the same time, while
plugging the power cable back into the scanner. The scanner will
enter a Demo Mode.
3.. Press the Cancel button on the scanner to start the test.
4.. To end the test, disconnect and reconnect the power cable
without holding the buttons down.


I've had exactly the same problem with my scanjet 5400c (blue distorted images) but after resetting the scanner (see instuctions posted above) the problem was fixed

If the scanner Fails it will give this message, Try the steps bellow to check if it can be cleared.

Remove both the ink cartridges from the All-In-One.
Unplug the power cord from the All-In-One as well as the power outlet.
Now move the carriage (carriage is the one which holds the cartridge) Too and Fro till you feel the carriage is moving smoothly.
Then insert the cartridges close the access door.
Plug the power cord directly to a wall outlet without surg protector.
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)
Now try printing a test page or make a copy

If it still makes a loud noise and the message comes up as scanner failure, then either the scanner or the scanner machanisum is bad, you may have to replace the unit

Good Luck

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 will come back and tell you if it works...
