HP Scan Jet 5370C

I need a schematic for the PC board. A power surge appears to have blown a resistor. I can't tell what size it is (was) because it is fried beyond recognition. The location on the board appears to be labled R105, can't quite read through the smoke stains.

Thanks to anyone who can help.

    Need schematics for Scanjet 5370.
    R105 and C152 burns

  • 3059LG Jun 02, 2008

    R 105 Blown form my HP 5370.

    I have read to remove the C118, is that the bes solution?

    Now R 105 becomes verry hot so I assume it will burn in a few seconds.

    Please answer to

    Thankls in advance,

It is a 30 Ohm Resistor, but 33 Ohm will also do.
My R 105 becomes very hot in a few seconsds also aftrer removing C118.

The R105 Resistor in the Australian version of the Scanjet 5370C, if that makes any significant difference, is orange black black gold. I don't have my handy translator so I don't know the impedance. I have no idea of the wattage, however it is about the same size as the R92.

I was hoping that may be my problem, but no such luck.

Good luck with changing the resistor.

Scan jet 5370c: main logic board has burned resistor "R105". what is the description, part no. or value of this resistor? thanks

The value of the resistor is 30 ohms (orange, black, black, golden (or silver).
I hope that helps you, but I suggest you that use a more powerful resistor, because it can blow again

Here is what one guy did

and Quote

[The Solution (for me):
Resistor R105 replaced by 30E (some Watts).
Removed C118 (was creating Shortcut for 12 Vdc) resistance after 7812(Q11) was only approx. 10E.
After this Scanner was working but after a scan there was always a white page.
Checked voltage after 7805(Q9), was only approx 2.5 Vdc. Replaced 7805 with a new one.
Now 5 Vdc is present again and Scanner runs again and is scanning as never before....]

The scan-light blinks but the scanner does not came on. scan-jet 5100 c

Try to turn off and turn on the scanner and test if its still not working, try to plug it directly to the wall outlet if its still not directly connected.
if both solution fails, you may need to have it repair/replace.

My HP 5370C scanner no longer works. When I tried to scan, a blank white image appeared. Tried a few more times, same thing. The next day I tried scanning again a pop-up appeared indicating ,no scanner...

The problem is in the connection cable, Check the cable that connects your scanner with your computer, If still not working, try replacing it with a new one.

Need to identify blown resister r-531 on main amplifier board

How do you know it is specifically that resistor? I suppose you have schematics or something that is telling you R531 may be an issue. If a resistor is blown it will likely be black or discolored somehow.

P4004 - Blown Components

if burned components are on output stage or amplifier section on board..Then look at the oposite side of amp..Both amplifier section should be a mirror image oof componentc from other..that way you can know the values of parts.If they are on power supply section ..Then you might need manual if available..

Replace the R 105 with a 30E one.
I read somewhere to remove the C118, it can work without

I know that a couple of you have had the same problem with the blowing 0.47 ohm resistors. I had responded quite a wile back, but forgot to make any updates. Kostiko is correct about the problem relating to these two 0.47 ohm resistors being blown. In my case on two different Haman Kardon models, this was true, but there could also be another issue. What i have found is even after replacing these resistors, the problem appeared to still be there. What was happening was that right after turning the receiver on, the resistors would blow again. What you need to do is replace the two small ceramic disc style capacitors on the same pcb as the fusible resistors, as they could be shorted as in my case. You could remove these capacitors completely, or replace them with a similar size of the same type, as they are really just there for filtering higher frequency noises from the power supply. You can check them with your multimeter first. They shouldn't shorted even in situe. I forget the size, but they are approximately 100 nano farads. Good luck. I have done this to my AVR135, and it has been running great for about 6 months now.
