Lines in film scans

When i scan any film [at 600 dpi or more] many times the images are coming in with a thin line through them horizontally - sometimes the line is green but most times it looks like maybe the pixels arent interlaced [not sure how to describe it technically] or maybe some are missing? on higher res scans the problem is more prevalent. its hard to ignore and also quite agrivating because its a new machine. anyone had a similar problem? im scanning in with manual settings but i havent fully dove into the instruction manual. id appreciate any help!

SOURCE: Scanned image has a line running through it

This could be one faulty sensor pixel or a speck of dirt on the scanner bar. It might be worth opening the scanner and carefully dusting the bar with a camera cleaner aerosol.

SOURCE: The documents are scanned but dont appear on later inspection, or if they do they are just a horizontal line across the middle

Try the version that came with the scanner Mine Was 3.0.1250.336 and is more stable than the new one.

If the 'noise' is in the same place with varying intensity it is definitely dirt on the glass. Clean with Isopropyl alcohol (rubbing Alcohol). Dont use any solvent.

Horizontal line on printed page


When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.

A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.

Tip

LPI, PPI,DPI conversions


Here is a conversion chart for DPI (Dots per inch) to LPI (Lines per inch) or PPI (Pixels per inch)

180 DPI................31 lines/inch or 68 PPI
360 DPI................63 lines/inch or 138 PPI
720 DPI................127 lines/inch or 280 PPI
1440 DPI..............255 lines/inch or 561 PPI
2880 DPI..................510 lines/inch or 1122 PPI

If you plan to enlarge your image, it is better to enlarge it when you're scanning rather than in your application. Each time you modify
an image, you lose some quality. Keep in mind when you enlarge a small photo, such as a 35 mm slide or wallet-size photo, you'll need
to scan at a high enough resolution to retain your image quality, but not so high that your file size is too large to be efficient. You must
manually adjust the resolution (dpi) to maintain the same image quality when you resize your image. For example, if you have a 300
dpi 2 x 2-inch image that you want to enlarge to 4 x 4 (a factor of 200%), increase the Scale setting to 200% or change the resolution to 600 dpi.

Images scan set at 300 dpi, end up 72 dpi


It depends on the physical size of the images. Size and resolution are related to each other. Let me explain:
You have an original, say, 2 inches by 2 inches.
You scan it with resolution of 300dpi (dots per inch).
You will get a file that's 600 by 600 pixels, right?
Then you look at it on screen, which has a resolution of 72dpi - if it's displayed without magnification, what size the picture will be? 600 divided by 72 = 8 and 1/3 of an inch, so on screen it will be 8 1/3 by 8 1/3 inches.

So, there's no such thing as a picture file's "real" resolution - we can talk about a resolution at a given size, because it's the horizontal and vertical size in pixels what's "real".

Therefore you have to ask what size the scanned picture is, and then look at the file you receive; in it's properties you will find it's number of pixels horizontally and vertically, and from that you can easily calculate (dividing the height in pixels by the height in inches) the actual resolution the file has been scanned at.
Then you'll know for sure if need to complain to the friend ot not :)

Need to get scanned photos to between 300 and 600 dpi


What I saw first off is that although the resolution indicates 96 DPI, the file size itself between the 2 examples are drastically different. You are putting raster images into MS Word for publication work, and that is a NO NO. Word was not created for any kind of high resolution printing. It's a glorified text editor that people seem to think is an option for printing. YOU WILL NEVER GET 300 or 600 DPI images out of Word. Ever.
To create your project for printing, you need to use software more suited for the task. InDesign and Quark are examples, but they are very expensive. In my opinion, Publisher would be better for this kind of project and I hate myself for saying that.
Talk to your Printer, find out his specifications for Applications and Linescreen for Printing. The minimum requirement is 280 DPI, but if the image is placed at 100%, 600 DPI is overkill.
Oh, and try to never scan a scan... you are looking for trouble... a little thing called a Moiré pattern comes into play, and it will make you images print NASTY!
I could go on about your post all day long, but if there is anything else I didn't explain, please post again.

Epson 3490 does not find the slide I put in the correctly positioned provided frame


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.

Please do the following to scan slides or negatives in manual mode of the Epson TWAIN:
1) In the program you are working from, begin the scanning process. If working in full auto mode, as the scan begins you will see a message that reads TO CANCEL SCANNING IN FULL AUTO MODE AND SWITCH TO MANUAL MODE, CLICK CANCEL. At this point, click CANCEL, then MANUAL MODE.
2) You will now see all Epson Twain settings displayed. If the scanner has not previewed automatically, click the full page preview button (icon of a paper with one corner folded down).
3) Ensure the settings on the right hand side of the Twain are correct. For example, the DOCUMENT SOURCE for transparencies must be either TPU: COLOR NEGATIVE FILM, TPU: MONOCHROME NEG or TPU: 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 you are scanning a black and white slide in true colors, choose TPU: POSITIVE FILM as the DOCUMENT SOURCE and BLACK AND WHITE PHOTO as the IMAGE TYPE.)
If the DOCUMENT SOURCE is flatbed, the scanner will not activate the backlight in the transparency unit. If the DOCUMENT SOURCE is greyed out and you cannot select a TPU option, close the twain, reseat the power/communication cable connecting flatbed to TPU, then re-open the twain and try again.
4) Ensure the other twain settings are correct for the type of scan you are doing.
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 guidelines on this; you will need to experiment and view the output to gauge the appropriate input DPI from the scanner.)
PREVIEW. If your scanner is doing an AUTOMATIC 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, click the CONFIGURATION button and uncheck AUTOMATIC THUMBNAIL PREVIEW FOR FILM, then OK, and try the PREVIEW button (page with corner folded down) again.
In this mode, you will have to manually marquee or crop the slides you wish to scan. Use the left mouse button to lasso one slide inside a box made of dotted lines, then click scan. Only the selected area will scan. Repeat this process (manually crop then scan) 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.
