Epson V750 power supply question

[chuck94022]

I'm currently on an extended assignment in China, but normally live in the US. I'd like to buy an Epson V750 to scan film while here. My issue is power - China is 220/50hz, US is 110/60hz. So my question: is the Epson power supply built into the unit, or is it a separate brick? If separate, I assume that when I move back to the US I can just replace the brick. I'd hate to have to buy a 110/220 transformer once back in the US.

Thanks,

I just checked the "brick" of my V750. It's nameplate says 100-120V 50/60Hz 45W Max input.

So you'll either need to get a small step-down transformer, or buy an Epson in China and get the US power brick when you get back, or the other way around, buy a US Epson and the extra China brick. An Epson parts supplier in the US here lists the US power supply for $40. Epson part # 2115843

Thanks Greg. Buying the US version in China is very expensive, almost double the price. As long as the brick is external, I should be fine with a China version. Thanks for the response!

Chuck,

the power supply for the V700 (and I suppose also for the V750) is a silly 24V/1.4A power supply with a standard connector. If you return to the US and can't get the US version of the power supply from Epson for a reasonable price or for whatever reason, you should be able to get such a power supply easily, 24V is a very common voltage used in many devices.

I had considered this when I wrote my response, but I had this thought: Regulation. While we don't know how well regulated the 24V coming out of the Espon adapter is, one has to assume that Espon has done the testing so that it does not cause any adverse affects like banding or electronic noise --> pixel noise. Any old generic 24V aftermarket supply, we know even less about their quality. IMO, a V750 falls into the category of "advanced optical equipment", and scrimping a few bucks on the power supply doesn't make sense to me.

Just my $0.02

The good news is that when I get back to the US, I'll have access to my entire electrical engineering bench, with volt meter, o-scope, frequency generator, soldering station, etc. If push comes to shove I'll just build one! ;-)

Thanks all,

FYI, I pulled the trigger on a new Chinese market Epson v750 today. I'll be scanning 35mm, 120, and 4x5, slides and negatives (C-41 and traditional B&W). My use of the scans will be primarily for online/web for the 35mm, if I want to print one big it'll get a professional scan, which they do here just fine. I'll decide on an as needed basis what do to for 120 and 4x5. When I previously scanned, I had a Canon 9950f, and it did pretty well on the MF and LF stuff. And it did fine on the small stuff, as long as I didn't have to enlarge too much. I'm hoping for similar results with the Epson.

Thanks for the help.

The V750 has a real resolution of ~2000-2400 PPI, if you're careful about getting the height adjusters on the film holders set correctly. That's good for 5x-8x enlargements, depending on your output's native resolution...8x10 from a 35mm, 16x16 from 6x6...

Have fun scanning!

V750 vs v750-M?

I received my scanner today. It works just fine, my first test (120 slide) looks great. For fun I scanned at 6400 dpi, knowing I would not pull any more detail but wanted to see what the tools would do. The resulting file was read by my editor, but it pretty much went catatonic trying to handle that many bits.

A question: The scanner I received is new, but it and the packaging say V750, not V750-M. Is there a difference? I also note there is no wet mount holder included. Is this an optional component?

The dealer is reputable and will accept a return if I complain, so not too worried in that regard. Is this just a regional difference, or is the M model different/newer/whatever?

Thanks,

Mine here in the UK is simply called the V750 Pro. If it says V750, you're good.

Again, here in the UK the wet mount is an option - you just contact Epson and they ship it to you for free. Strange arrangement, but there you go.

The first thing to do with your new V750 is experiment with different holder heights. You've got three: +, O or no foot. Try them all. FWIW, after much experimenting I've found little perceptible difference between them on my machine, and I did look! I've set my holders at O, since that seemed to provide as good a result as any.

Try and forget what everyone says about this machine. Using Silverfast carefully, you can obtain good scans from any format. The main problem is CA, which needs fixing in post. Don't judge the results until you've sharpened - these scans reward strong capture sharpening.

Thanks artobest. I'll contact Epson for the mount. You are right, that is a strange process.

So far my test scans, with no tuning, are as good or better than my old Canon 9950f. I got enough out of my first 35mm B&W that I am sure I'll get reasonable usability from those scans, and my MF scans are just fine. I'm looking forward to the results when I really get serious about making the highest quality scans.

Forgive me, but "CA"?

Sorry, Chromatic Aberration. There seems to be a bit of CA turning up in my Epson scans - can be tricky to remove if you don't want to introduce it somewhere else. Lightroom/ACR helps.
