EPSON SCANNING TIPS AND TROUBLESHOOTING GUIDE

Epson Perfection 3170 Scanner

SELECT A SUITABLE RESOLUTION

The best scanning resolution depends on the purpose of the scan.
When you specify a high resolution, the number of pixels increases and the scanned image

becomes finer in texture. However, increasing the resolution causes the file size to increase. For
example, an 8.5 x 11-inch original scanned at 300 dpi can produce a 24MB file. The same original
scanned at 72 dpi creates only a 1.3MB file. Large files take longer to process and print, so select
the lowest possible resolution that produces acceptable quality.

Specify a suitable resolution according to your scanning purpose. Recommended resolutions for
scanning print material:

PURPOSE RESOLUTION
Web pages 96 dpi
Sending E-mail 96 to 150 dpi
Printing 300 dpi
Saving as a PDF file 300 dpi
Sending Fax 200 dpi
OCR (Optical Character Recognition) 300 dpi

Use Target Size to specify the output size of the scanned image.
If you are enlarging your image, you must increase the resolution (dpi) proportionally to maintain

the resolution of your original. Try scanning slides at 1200 dpi or higher.
If you reduce the size of the image on a page, it does not decrease its file size.

PLACING FILM OR SLIDES ON SCANNER

You can scan 35mm slides, 35mm film or negative strips, and Medium Format
transparencies on the Epson 3170 using the appropriate film holders which come with the
scanner.

1. The first step is always to open the document cover and
slide up the reflective document mat gently to remove it.

Please remember to replace the reflective document mat
when you are finished.

2. Second, load the transparency into the film holder and position

it on the document table.
Now go to the section listed below that matches the type of

transparency you want to scan.

SCAN 35 MM SLIDES

1. Place the film holder on the document table so that
the triangle mark on its tab is aligned with the triangle
on the document table. The projection on the tab then
goes into the hole on the document table.

2. Place slides in the holder, base side facing down as
shown below.

NOTE: The base side of the film is the side where
the film maker's name and film ID numbers can be
read correctly. Also, when you look at an image on
the film from the base side, the image should appear
normal, not reversed.

NOTES:

• Make sure the document cover is completely closed; otherwise you cannot obtain

proper colored images.

• A newton ring (ring-shaped stripe pattern) may appear in the scanned image. To

remove the newton ring, place the film with the base side facing up and preview using
the Thumbnail Preview; then reverse the previewed image by using the Mirroring
button.

SCAN 35 MM NEGATIVES AND FILM STRIPS

1. Slide the edge of the strip into the 35 mm film

holder, base side facing down. Then place it so
that the entire frame is positioned inside the film
holder.

2. Place the film holder on the document table so that the
triangle mark on its tab is aligned with the triangle on
the document table. The projection on the tab then goes
into the hole on the document table.
