    Or to be even more precise, here's a quote:




    "The value of the resistor is 30 ohms (orange, black, black, golden (or silver)."

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....]

I need to know the value of the Resistor "R1" in


Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

Burned resistor R105 on circuit board HP 5300 scanner


Hello there:
if you contact radio shack you can get all of the technical information about the resistor from them, as far as fixing it i would contact the manufacture of the unit to see what options are avaiable ok.

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.

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