SOURCE: Scanner wont scan transparencies properly

On the 4990, make sure that you have unlocked the lid of the scanner. The lock is located underneath the lid.

Please do the following to scan slides or negatives in manual mode of the Epson TWAIN:
For scanning transparencies in HOME mode - for EPSON SCAN models, not Epson Twain/Manual mode models.
1) In the program you are working from, begin the scanning process. If working in FULL AUTO MODE as the scan begins click PAUSE or CANCEL, then change "Full Auto Mode" to "Home Mode".
2) You will now see all Epson Scan settings displayed. If the scanner has not previewed automatically, click the large preview button to get a visual of what is on the scanner.
3) Ensure the settings on the Epson Scan are correct for what you wish to scan. For example, the DOCUMENT TYPE for transparencies must be either "Color negative film", "B&W Negative Film" or "Positive film"*.
* FILM here indicates that the item being scanned is transparent to light; this setting is also used for slide scanning. Positive indicates that the image is in true colors (ie the grass is green and sky is blue), whereas negative indicates reversed colors, as produced in some photo finishing processes.)
If the DOCUMENT SOURCE is set for a flatbed related option, ie PHOTO, the scanner is looking for reflective items and will not activate the backlight in the transparency unit. If the DOCUMENT TYPES for "FILM" are greyed out or cannot be selected, close the Epson Scan, reseat the power/communication cable connecting the base of the scanner to the transparency unit, then reopen Epson Scan and try again.
NOTE for PROFESSIONAL MODE users: DOCUMENT TYPE should read TRANSPARENCY for film scans.
4) Ensure the other scanner settings are correct for the type of scan you are doing. For example:
IMAGE TYPE should be color photo for all positive or negative color transparencies, or BLACK AND WHITE PHOTO for monochrome transparencies.
DESTINATION is unimportant, however you should select a RESOLUTION appropriate to what you plan to do with the scans. (There are no hard and fast rules for DPI. As a general guideline, if you are saving scans at original size, a resolution ranging from 400-600 DPI should capture enough information to faithfully record the image. If the slide or negative will be enlarged, you will need to increase this DPI accordingly. We have no means to calculate what your exact needs will be in this situation; you will need to experiment and view the output to gauge the appropriate input DPI from the scanner.)
PREVIEW. If your scanner is doing a THUMBNAIL PREVIEW, the slides will automatically preview and appear in boxes on the left side. Here, you can select or deselect the slides you wish to scan.
If you recieve a message that the scanner could not find the film, or you see in the preview that part of the scan is cut off, click the down arrow next to the large PREVIEW button and click NORMAL, then PREVIEW again. In NORMAL PREVIEW mode, the scanner will capture all information on the flatbed; you will then have to manually marquee or crop the slides you wish to scan. Use the left mouse button (click, hold, drag) to lasso one slide inside a box made of dotted lines, then click scan. Only the selected area will scan. Repeat this process for as many slides or filmstrips are on the bed.
5) Click CLOSE once scanning is complete. The images will now transfer to the application in use.

SOURCE: How to Scan a Picture onto the Computer

These are the steps:
- Have it on the scanner setting (by pressing the big silver button on the left)
- Press page preview
- Press the colour or black print button (which are also known as the 'start' buttons)
- Then it should link it to your computer.

See ive done this but it STILL hasnt worked, these are the steps the manual says ... and my colour print and black print (aka start buttons) work!

SOURCE: I cannot get clear scans from my photo negatives

If you are seeing pixelation, the issue is either insufficient resolution during the scanning process or a problem with the output device. If it's a focus issue, which will NOT cause pixelation, the problem may be the height of the negative holder. The Epson Perfection V series scanners have a fixed focus point which only adjusts between two settings depending on whether you select the film holders (which raise the film off the glass) or the film guide (which scans film directly on the glass) in the software options. If you are going to scan transparencies or negatives, familiarize yourself with the holder height adjustment issue and be willing to experiment with different height settings until you are getting optimum results. This is not documented much at all in the Epson user manual but there is a little bit about it, including some examples of results at different settings, here: Apparently every scanner is slightly different so even though the lowest holder foot setting (default) is working best for some, other settings work better for others. On my V700, I have the feet on the film holders set to the highest setting plus I shimmed them with a 1mm piece of styrene before I could get the scans in focus. Once I found the right height though, I've been able to get beautiful scans from this machine. BTW, scanning negs directly on the glass will almost always result in Newton Rings.

If the lines are in the same location for all scanned outputs, it is clearly dust on the scanner glass. Clean it thoroughly.

    Hi, I have Canon Pixma MP270. IS it possible to scan photo negatives and change to colour prints. thanks. Blair

    A multi-purpose printer scanner cannot scan negatives or slides.
    You need a slide scanner or a flatbed scanner that is capable of scanning negatives and slides. Not all flatbed scanners are capable of scanning slides and negatives.

    I replaced the LCD monitor on my asus eeePC900 XP and everything is great, but I can't adjust the brightness. If I press Fn and F4 which s to lower the brightness, I get an ''LCD only'' message. It is on...

    FN+F3 should increase the brightness and FN+F4 should decrease the brightness (or the other way around). Failure in that, you should try doing this through your operating system or through the BIOS

    Bad contrast with scanner


    That's the way HP does things. There are no rheostats or pots to adjust. It's all done electronically now, with chips and things.

    You never said how it does with color or greyscale photos or drawings.

    As for the RGB=(64,64,64), that's about right for the scan picture settings and the mixed (text and graphics) setting, and is particularly true for color picture settings. Have you tried using the setting for drawings (or line art), specifically greyscale drawings? Usually the greyscale lineart or drawing setting will render black text. You might also try scanning with the settings set for Text. If the greyscale drawing settings or greyscale text settings do not produce black text, try reinstalling your software and drivers.

    If the contrast stays the same for all settings after reinstalling the software and drivers, and if it doesn't scan color and greyscale pictures correctly, then it sounds like your scanner is going bad.

    As for the scans you've already done, you can darken the text by taking it into a photo editor, such as Paint Shop Pro or Photo Shop, and adjust the contrast and brightness to get the effect you desire.

    My pics

    Using the highest quality setting, scan your photos with a flatbed scanner. Then save them as .jpg files. The result will be quite acceptable, providing that your original shots are in good condition. If you have suitable photo software, you can sharpen them and adjust the size, brightness and contrast and so on. Great fun if you have never done it before. Don't forget to back up all your cherished data such as photos.

    Hope this helps

    The LCD screen is hard to see. What should I do?

    If the LCD screen is too bright or too dark, adjust the LCD Brightness setting in the Setup Menu. If you are shooting photos outdoors in bright light, move the joystick to the icon showing the sun over shaowed area to turn on Outdoor mode and make the LCD screen easier to see in bright light.
