Re: Cap. plague in Minolta DiMAGE Scan Elite 5400?


Apologies, I see this only now. Thanks so much, really appreciated

In the end, though, I realized that the Konica Minolta website does indeed have the full set of utilities and the scanner program. The download was so small (~6 Mb) that I assumed it contained only the driver, but does include everything (ah, the good old times when a complete program could fit on a few floppy disks

I managed to scan ~2,700 slides with the original program, on the latest Windows 10 (just needs the right driver,...

Re: Cap. plague in Minolta DiMAGE Scan Elite 5400?

Answering my own post: after looking at a few similar CCD datasheets (couldn't find one that looked exactly like mine), I realized that most CCDs for scanners are indeed powered with 12V. Replacing the 7812 seems to solve all problem, luckily there doesn't seem to be lasting damage.

For what is worth, I'm pretty sure that 6 fast flashes / pulses / blinks of the LED on a Minolta DImage Scan Elite 5400 II mean that the firmware found a CCD imager issue during self test (that explains why it happens right after the LED...

Re: Cap. plague in Minolta DiMAGE Scan Elite 5400?

I'm also trying to repair a Dimage Elite 5400 II (the new model, the one with a LED light not CFL)

I found a 7812 chip that looks like a 12V voltage regulator, but the output is only 2.2V, even when lifting the output from the PCB (I was checking to see if the problem was with the regulator or the circuit following it). See picture attached.

While I find strange that the scanner uses a 12V rail, I cannot see what else that SMD chip could be if not a 7812 voltage regulator. The right pins are connected...

Re: Bakon 950D "Extra Crispy" mod (19->24 Volt)



Old thread, I know, but one can always hope for a reply

I plan to make this change: I really like my 950D, but it's a bit anemic for some of the soldering I do, and I'm forced to keep cranking up the temperature, which is a bad idea

I live in the USA, so 110V mains here. Which one is the current limiting resistor, and what values should I try to use?...
