Epson 3200 transparencies

[Ian]

Hi folks,

I have a stack of old (mostly1890s) family photographs in the form of
glass negatives. The plates measure 120mm x 164 mm, image size is
114mm (4.5") x 158mm (6.25") . I want to scan these on my Epson
Perfection 3200 scanner.

The transparency adapter on the scanner is specified as being 4" x 9"
and when I scan using either the Epson Scan software or Vuescan I get
an image which is 100mm (4") wide. The scanner illuminator is 120mm
wide - does anybody know if it is possible to use the full width of
the lamp so that I can scan my transparencies in one pass?

I am using a home made negative holder (cut from mounting board) which
centres the plate under the illuminator and has a cut-out at the end
to match the standard Epson holders.

Any suggestions would be very welcome.
TIA,

Ian

I think the extra 10mm on each side is to make sure there isn't any light
fall off at the edges. I'm not sure if the 3200 is limited by
hardware/firmware (marketing). I know the 4870 has a full light lid.

Not true. The window on the Transparency Illuminator on the Epson 4870 is roughly 6" x
10.5" ... and the Specifications say "Versatile, built-in transparency unit (6" x 9") with
moving light"

See

for more information.

PS - I've had good luck scanning 5" x 7" transparencies with mine ... haven't tried 8" x
10" transparencies ... YET.

Yes you can.
EPSON Twain 5 - Go to the Configuration button and select the Preview
tab. Deselect the Thumbnail preview option.
EPSON Scan - In the Professional mode click on the drop down arrow to
the right of the Preview button and select Normal.

Both these options disable the automatic thumbnailing and allow the
scanner to scan the full area under the overhead light source.
Remember to use your own Marquee or the exposure will be incorrect.

Thanks Tim,

I had tried this but the width of the scan is still a maximum of
101.6mm! Do you get a different figure?

The width of the lamp is approx 120mm so I think the limit must be
embedded in the hardware / driver .

Ian -

You have the correct limitation on the 3200. As you (or someone else here)
stated, I am pretty sure that the limitation is there in order to avoid
light falloff at the edges.

Yes this is correct the limitation is to avoid fall-off in
illumination and is written into the driver.
