Dirty scans getting dust-like spots on both reflective and transparency scans, non-uniform,and random, some are like small hairs, but most are aggreagates of small(white) dots. Glass and films, etc are clean. Possibly a dirty sensor?--but wouldn't that make the dirt in a regualr patter?

Small white dots would indicate progressive failure of the CCD[sensor] or perhaps ingress of dirt to the inside of the glass. hard to say exactly with out seeing the machine.

What color is the polar bears skin?


A polar bear's skin is actually black. It's black so it can soak up as much of the sun's rays as possible. Polar bears have almost transparent fur over black skin. Reflection of the sunlight from the densely packed transparent hairs makes polar bears seem to be white. The bears' black skin absorbs heat from the sun. The seemingly-transparent fur is made up of hollow hairs called guard hairs. These air-filled guard hairs help transmit heat from the sunlight to the polar bear's black skin as a solar heat collector. In turn, the reflection stops the heat being lost from their black skin. Reply if you have any more questions. Good Luck, Cooper. (Please give a good review, I am doing this for a summer job!)

How to Clean Scanner Glass


Steps how to clean scanner glass

1. Unplug the power cord.
2. Clean the outer case with a cloth dampened with a mild detergent and water.
3. If the document table glass gets dirty, clean it with a soft dry cloth. If the glass is stained with grease or some other hard-to-remove material, use a small amount of glass cleaner and a soft cloth to remove it. Wipe off all remaining liquid.
4. Ensure that there is no dust on the glass of the document table. Dust can cause white spots in your scanned images.

*** CAUTION: Do not press on the document table glass too hard.

5. Be careful not to scratch or damage the document table glass, and do not use a hard or abrasive brush to clean it. A damaged glass surface can decrease the scanning quality.
6. Never use alcohol, paint thinner or corrosive solvent to clean the scanner. These chemicals can damage the scanner components as well as the case.
7. Be careful not to spill liquid into the scanner mechanism or electronic components. This could permanently damage the mechanism and circuitry.
8. Do not spray lubricants inside the scanner.
9. Never open the scanner case.

***NOTE: Wipe the inside of the document cover and the scanner's document table before scanning transparencies.

I have lost the Transparency light source cover. Is there anywhere to purchase this part?


You could just get a piece of white cardstock and put it between what you're scanning and the lid. This will eliminate the writing on the cover showing through. The transparency lightsource isn't on when you're scanning reflective.

MY SCANNER WILL SCAN PRINTS BUT NOT TRANSPARANCIES THE SCANNING LIGHT WORKS ON PRINTS BUT NOT TRANNYS, ANY IDEAS PLEASE


Flatbed scanners that can scan prints and transparences had two light sources.
One for normal prints (ie reflective light source, the light shines from under the glass to the print/photo and reflects off this print/photo to the optical sensor).
On a scanner that can scan transparences there is a second light source in the lid that shines through the transparences pass the glass to the optical sensor. The light source under the glass is not used in this case.
The scanning software automatically selects the right source when you select to scan prints or transparences.

EPSON V500 trying to scan 2.25 x 6.5 transparancy


its possible they are right, But try puting acoulpe of sheets of plain white paper behind the transparency before copying as a buffer . The scanner is seeing the transparency reflected back causing distortion. with the paper blocking the reflection, it should scan perfectly

If you know how to get the lens out, then it shouldn't be too difficult to clean it, but it is tricky. Having it serviced would be the best option. However, if the pictures are clear, i wouldn't bother much, as giving it for servicing would probably end up costing more than the price you paid for the camera!

Cheers!

Spots on image when using built-in Speedlight flash


As is common in many compact digital cameras where the built-in flash is very close to the lens strange reflections can appear in images under certain conditions. Particulate matter in the air in front of the lens (between the camera and subject) such as water vapor (as in a cloudy day), smoke, dust or other items can reflect light directly into the lens causing neutral colored white/grey semi-transparent spots to appear in the image. In extreme examples there may be many of these spots in an image or there may be only one per image. Also, since these spots are completely random they will move or disappear from image to image. For example, if two images are shot consecutively with the same camera settings one image may have spots while the other is clean. To avoid these spots: When possible, avoid photographing in smoky, dust, or cloudy areas Do not use the camera's flash in locations such as above Use an external Speedlight flash if a flash is needed Review images on the camera and re-shoot if spots are visible Cleaning the lens will not have an effect on these spots, as the particles that cause this are not on the lens itself.
