Question about HP Scanjet 3300c Flatbed Scanner

1 Answer

Blown fuse? My scanner was working well and suddenly I plugged in wrong power pack and might have blown a fuse..I looked all over the web and can't get a verification on where it is located. I took apart scanner and see a small fuse that seems to be "locked in" between two fixed posts..I am afraid of bending them to get fuse out but is this what I need to do? Or is there a fuse that is elsewhere inside the unit...I appreciate any feedback on this topic..Dan

The power to my HP 4400c scanner is not working - just bought a new power cord from HP and still no power. what could be the problem?


Dear Mail472,

We are sorry to hear about your continued issue; even after purchasing a new HP power brick for this scanner.
Sadly, the power brick is only half of the puzzle that provides the full power to this scanner it needs to function. If the unit will not power up on the new brick, then the primary control board inside will need to be examined for a blown fuse or may be dead.
If you are confident enough to open the scanner and check the fuse, unplug the power to the scnner, open it up, and check the fuse. If you would rather; I recommend getting a quote from a local computer store to have the scanner repaired and tested. Or simply purchase a new scanner at a local Retail outlet like Wal-mart, Best Buy, Office Max, or Staples.
Whatever you decide, best of luck with the scanner.

Thanks for using FixYa, and have a great day!

I accidentally plugged in epson nx110 to 110v when i shoudl have plugged it in 220v , burnt smell and no power at all


Not sure why it burnt going from 240 down to 110volts. The unit should not have worked. However, if it is a 110 volt machine and you plugged it into 240 volts... different story... At best you have blown the power supply board or board fuse.. At worst, the machine will be fried inside.

We are not able to get our Fujitsu fi-5120C out of status 8. We've turned it on/off unplugged it changed one of the pads (as it was bent). We left it alone for a day and it's still not working. Do you have...


Hello,

Thank you for contacting FixYa.

Please clarify if the error is E8 or some different error. E8 error indicates that SCSI fuse is blown. When 5V, 3.3V fuse is blown, the scanner does not turn on and E8 error is displayed. Check the SCSI fuse status. The SCSI fuse is located in the Control PCA marked as TH2. This alarm is detected during initial processing immediately after power-on.

Probable causes:
- Defective SCSI cable. #Check the SCSI cable status.
- Other SCSI device malfunction. #Check the SCSI device.

1. Does the same symptom occur after turning OFF and ON the scanner?
To check, press power button of the scanner for more than 2 seconds to turn it OFF, and after more than 2 seconds elapse, press the power button to turn the scanner ON.

2. Check if the SCSI cable or other SCSI devices connected to the scanner cause this error. The scanner can work even after this error occurs. However, to remove this error you may have to replace the Control PCA.

Hope the above information will be helpful.

Please revert if you have further queries.

Thanks & regards,

TechSatya

Possible blown fuse...


There is a fuse. And is soldered ti the power supply board. remove the power supply board and very carefuly heat the end of the fuse connector wire where it pokes through the board while gently pulling it from the other side with a pair of needle nose pliers. you will have to remove the fuse from it's holder to read the amp rating. You can get a replcement fuse from Radio Shack.

CanoScan8400 Suddenly Doesn't Work


I had the same problem about a year ago. The solution was to replace the power cord AND don't leave it connected to the powers source when the scanner is not in use, or it will burn out again.

HP 4070 Doesn't Power Up


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.

Apple laptop M8407 vs. n670u canoscan


Keep in mind that connecting a specific scanner to the computer would have nothing to do with the computer now powering on unless there are physical computer hardware problems. Disconnect any uneccessary external peripherals from the computer (printers, scanners, webcams, etc.) and see if the computer will power on. Remove the computer battery and put it back in. Check power connections and test to make sure the electrical outlet is working by plugging something else into it.

The fuse is there to protect the scanner's circuitry in the case that the 12V, 1.25A power source, the transformer, adapter, wall wart, or whatever you wish to call it, goes above the rated values. No higher or lower V or A should make it into the device in order for it to operate within its designed range and fail. Usually there is a slight surge of some sort that blows the fuse caused by a lightening strike near by, static, or any # of other possibilities. The adapter itself is usually weakened over time, rather than the source of this increase. When the adapter goes too low, the scanner will not operate properly and usually windows will stop recognizing it as a usb scanner. At this point the various scanners on the market will give various different reactions that you'll see described in other problems in this forum, but they are all related to a reduction of the input to the scanner resulting in insufficient or erroneous output signals to the computer and windows various responses. Although the fuse is the first point of protection of the scanner circuitry, it isn't needed most of the time if you use a good surge protector to prevent any extraneous voltages from getting into the adapter in the first place. In other words, the surge protector is a 'fuse' for the adaptor, and subsequently, the scanner itself. So my recommendation for those who have equipment that is normally much more difficult and expensive to repair properly, such as a soldered-in, blown fuse (which would be professionally repaired by replacing the entire circuit board rather than just the fuse), is to bypass the fuse with a piece of wire soldered between the two metal end-caps across the top; a very simple, very quick solution. Then use a good surge protector as your 'fuse' to protect the scanner's circuitry. The obvious caveat is that you are taking responsibility for disabling the protection that was originally designed into the scanner to keep the delicate circuitry from failing due to extraneous voltage surges. There is very little risk of fire, but 100% risk of having to have the very same circuit board replaced or buy a new scanner.
