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.

Verify whether or not the date and time appear on your Brother machine's LCD. If anything is displayed on your Brother machine's LCD, then it is most likely receiving power.
If your Brother machine's LCD is blank, continue toStep 2.
If your Brother machine's LCD displays a message other than the date and time, please refer to the FAQ about the message being displayed for further information.
Verify the Brother machine's power cord is connected securely to the power outlet. If you are using a surge protector, extension cord, or power switch, disconnect it and plug the Brother machine directly into the wall outlet.
If the Brother machine is turned OFF, its LCD will be blank. Please make sure the Brother machine is powered ON by pressing and holding theOn/OfforPower Savekey. This key is located in the upper-right corner of the control panel.
If your Brother machine's LCD is still blank, connect it to a completely different, known working power outlet. If the Brother machine powers up, then the problem is related to the original outlet.
Confirm the power outlet is working by plugging another known working device (a lamp, radio, etc.) directly into the same outlet. If the other device does not work, the problem is related to that power outlet. If a wall switch controls the outlet, verify that the switch is ON.
If your Brother machine still will not power on, please contact Brother Customer Service.In Case You Still face Problem and Need Online Assistance Then Please Follow Us For On :

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!
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
