Epson V600 glass cleaning. . .


Recommended Posts

"I took it apart again and the stripe problem is still there."

 

- That sounds like a speck of dust sitting on the 3-line sensor and partially blocking one or more of the strips of RGB filtered 'pixels'.

 

Often the lens and sensor assembly isn't fully enclosed, so locating the scanner lens and using an air blower behind it might well shift the offending particle from the sensor. The lens and sensor are located behind a delicate 45 degree mirror, so at your own risk obviously.

 

 

Thanks for the tip but with the ISRD broken I am not going to work on it again. As it is now I can still use it with fresh developed negatives which is what I do the most. However I am going to purchase a new V600 shortly or possibly the V800. I am just trying to decide if I want to buy a 4x5 or not. E6 photography with a 4x5 would possibly yield some great things in print and some terrible news to the wallet. I did just upload a photo that I took this morning with Ektar at Gibson beach in the classic camera forrum. Scanned with my broken scanner.

Remove the two screws at the bottom of the post sockets. The lower sections can now be separated as shown in #8. From here on out extreme caution must be observed, as the internal guts of the scanner contain several, non robust, ribbon cables.

I pivoted the bottom glass section to the left being careful to not put any tension on the cables you will observe in the front section. Sorry but from this point I had my hands full balancing the glass section and cleaning the fungi away. I use a three prong approach on the little beggers ! First a slathering of 91 proof alcohol (soaked rag), then hydrogen peroxide, finally lens cleaning solution. Cleaning takes a bit of time, but think of this process as a waltz with your favorite camera lens !

Oh, the glass on my V600 is held in place with adhesive's. . nothing mechanical.[ATTACH=full]1272329[/ATTACH]

That oughtta kill the little b&$+@rds!

I ordered a new one this morning. Plan to keep the old one for possible parts and will just store it away in the box the new one arrives in. . Thank you for all the help but I am just a poor scanner repairman. Glad I am not replacing a V700 or 800.

I don't think I've ever seen Newton Rings, has any one got a picture or scan to show me what they look like.

 

I'm using an Epson V800 with an Epson V700 4 strip 35mm negative holder, I initially thought having the 4 strip holder would speed up the scanning process, ie fewer changes of strips in the negative holder. This is not so. With the V800's 3 strip holder you have to load it twice for scanning a 36 frame film. Once for the first 18 frames and once again for the second 18. With the 4 strip holder, you still have to load it twice, once for the first 24 and then again for remaining 12 frames. Maybe Epson was on to something by offering two holders of each for format with the V850, load the next holder while the first one is scanning. Maybe I'll switch back to the 3 strip holders for their ability to hold the film flat.

 

Isrd doesn't work on B&W, but you already knew that.

Hi Greg,

 

I will look in my work...my sloppy work has generated such things. IIRC they are related to reflections. You will get them when scanning the glossy side of the negative whe nthe image isn't quite flat. I suspect if you google this qou will find answers too. IF you imagine the irridesence you see in a soap bubble that is distorted rings.. something like that but then flat on a scan.
