Epson V750 a lot of problems...

[corto]

Hi Everyone,

I am Simone from Florence, Italy. I just purchased a used Epson V750 from internet. Everything works fine with normal documents, but as soon as I scan color or bw negative everything turns wrong. In the attachment I included the preview (looks fine) and the ugly scan (does the same thing when I zoom from the preview).
Do you think that is a software issue or a sort of defect with my unit.
Thanks for your time guys...

Have you read the manual?
Do you have all the modes se correctly?
Did u remove the white document scanning pad thingy that covers the light source?

[ScottPhotoCo]

Likely a software issue. Like Vinny said, go through the manual and experiment with the software. I use both the epson software and Silverfast 8.

[JW Dewdney]

give us a screenshot of your RGB histograms and i'm sure you can get some better feedback...

It does kind of look like he forgot to take that blue sticky coating off of the scanner doesn't it?

But probably he has it set for color negative when he scanning slides phone or something silly like that...

Please double check your settings and good luck!

I was referrring to the document scanning pad.
I doubt the blue protective film you speak of remains on this machine since he purchased it used.

Guys, its ok ...I'm Italian, but I'm not so lazy that I don't ck the blue film glass cover or the white pad protection or if I am scanning negatives or transparencies... come on!

There are three options with the Epson software ...

Which type of holder... (Holder, reflective, or film area guide) make sure it's NOT "reflective" and if you are using the holders make sure to select "holders"

Next make sure it is set to color 48bit color is best...

Then select film TYPE (different from scanning color) probably color negative? From the looks of the scan.

Next turn off the darn anti dust stuff etc.

I don't know why the images would be so strange UNLESS you accidentally (or the lab?) cross-processed the film in the wrong developer, but that seems a bit hard to believe they would mess up like that.

Also, check that the film is in the holder and the edges of the film are not exposed away from the black edges, it could be some kind of "light piping" where the scanning light hits the edge of the film and sends light through the film causing a strange discoloration, but truly I doubt that's the issue...

I've never seen this, it's very strange...

The only other thing I can think of is the color profile attached to the scanner has been altered.

I've never actually adjusted the color profile on my own scanner as the colors seems just perfect for me right out-of-the-box, but if the previous owner decided to adjust them, maybe they need to be readjusted, I'm not sure of the full procedure so I can't help you with that part but see if you can find the area of the program that deals with the color profile and see if maybe there are different options including resetting it back to normal? Or factory settings?

Best of luck, this is a tough one to figure out!

Salud!

Switch on the V750 wait 30 seconds
Start EPSON Scan software
At the top right of the Epson Scan control panel set the Mode: to Professional Mode
Where it says Document Type: set it to Film (with Film Holder)
Next set film type to whatever film you are about to scan
If you selected B&W Negative Film set the next option, Image Type to 16-bit Grayscale
If you selected Color Negative Film set the Image Type to 48-bit Color
Uncheck Speed priority scanning
Set Resolution to the biggest it will let you work with, I use 3200 dpi for Black and White except for whole plate and 8x10 when 1200 is about all it can cope with
Ignore target size because you will use Normal rather than Thumbnails on the other panel (where you see your previews)
Click Preview let it make the preview scan.
After the preview scan has been made outline the first frame with the cursor, which will draw a box of broad dotted lines around the frame.
On the right hand Epson Scan panel click Trimming to Off
Click off Unsharp Mask and all other boxes underneath
Now click on either the icon with a black histogram representation on it this gives you another box over on the left for you to adjust the levels with. When you have those as you want click the Close button on the bottom right of this screen and it will disappear
Draw round the next frame as before and repeat the operations of no trimming, no unsharp mask, no dust etc etc. DO NOT LET THE SCANNER DO ANY OF THESE OPTIONS. You keep control for yourself as the scanner will SPOIL your images if allowed to do all these ambitious things on its own.

For colour work still outline your frames but in this case accept the standard output and make your changes later in Photoshop or similar.

When you have outlined each frame and set each one up (if B&W) then click the first frame.
Then in this same box with all your frames displayed at the top left you will see an icon that looks like a torch or something similar, click that and then click All.
Then back on the other control panel click Scan and then answer the questions where you want to save the scanned images to and what name and numbering sequence you want.

As has been said already, make sure the white background pad has been removed from the lid. You should be able to see through all of the glass in the lid. Another thing to watch is that the holder is correctly positioned on the platen. I thought I'd broken mine when scan after scan was coming out blank, as soon as I positioned the holder correctly, the problem went away completely.

Come back if you still have any problems...

Are you using Epson TWAIN or Silverfast?

[VictoriaPerelet]

Make sure your calibration area is not covered by paper or transparency

[Andrew O'Neill]

If you are using a film holder, make sure that it is not sitting upside down othetwise the calibration area will be covered over and you'll end up with scans similar to yours.

[koh303]

This looks more like an epson driver/scan software auto correct error due to selection area.
A common problem, have you tried selecting a smaller section of film to see if the scan area gets "corrected appropriately?

[Regular Rod]

Have you tried the suggestions in post #10 http://www.largeformatphotography.info/forum/showthread.php?111931-Epson-V750-a-lot-of-problems&p=1120176&viewfull=1#post1120176 ?

To isolate whether it's the software or the hardware (very likely it's the former), download vuescan (for free) and see what you get from it. In the end, vuescan is highly recommended for serious scanning any way so might as well give it a go.

Remember to select transparency, colour negative, etc. before scanning.

Give VueScan a try, it is quite affordable and by far the best and most consistent scanning software on the market.

[Bernard_L]

In the attachment I included the preview (looks fine) and the ugly scan
No, the preview does not look OK! It has a strong blue cast.
+1 on vuescan. Get a (free) trial version. If you decide to buy it, I recommend the pro version (lifetime updates)
Make sure you select color negative as input medium in the first tab (input).
In the crop tab, make sure the crop area selected for the actual scan does not include any part outside the actual image area.
In the color tab, select auto white balance to start with (later you can learn more sophisticated techniques, like balancing from a gray card shot). Don't waste time with choices for films in the color tab, just take generic color negative; your problem is far bigger than the distinctions between various films.
And, please report back to the people who gave advice here.

Corto,

Haven't heard a follow-up from you. Did you get it figured out? The advice from Regular Rod was very specific, and should have addressed the mechanics of scanning with the 750.

Rather than switching to a third party scan software package, I suggest sticking with the Epson software first so that you don't introduce too many other variables into your problem. You could download the latest Epson Scan software from their website, but I would stick with the Epson software until you get appropriate results.

If you've got it fixed, please let us know. Thanks!

[Delfi_r]

The Epson Scan Software saves its settings. I've solved one problem resetting completely.

[onnect17]

It just looks like a color negative (c41) scanned as a positive then inverted without any corrections...

Looks like corto has left the room. Lost interest in the conversation, and does not care to acknowledge the time spent by other members trying to help him.

and sometimes life gets in the way...

[corto]

Guys, I'm sorry for not giving a voice, but sometimes life/work/daughter/parents/problems and problems and problems... gets in the way. There are no words for say thanks to all the people that are helping me with my problem. I tried everything you guys told me, I am not new to Epson, I owned a 4990 and sometimes I use a v700 in the photo school where I work, here in Firenze. I guess that could be an hardware problem. Seems that when I scan films the bottom light does not work at all. I give up! I'll send it to the service. Thanks a lot to everyone.

[Brian C. Miller]

The bottom light is supposed to be off when you scan film. The top light, in the lid, should be on when you scan film.

Is the lid unit plugged into the scanner?

[corto]

Yes, the top light is on and moves back and forward as should do. I will let you know from the service...

[corto]

PROBLEM SOLVED!!!! The guys at the Epson Service store told me that the upper sensor was defective. So they changed the part and now seems to work fine. Thanks again to all of you for your advices.
