Question about Office Equipment & Supplies
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
[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....]
