This bulletin was created to inform customers of issues that can occur when using the
Perfection 4990 Series or Perfection V700Photo / V750 M-PRO scanners to scan large film or
large X-rays such as dental panoramic X-rays.

Description of Issue:
When customers scan large photographic film or large X-rays such as dental panoramic X-rays
that are typically 5" x 11", the preview and final scan may appear “washed out” or display lines.
This issue occurs when the panoramic X-ray is placed on the scanner bed lengthwise (long
side of film placed against long side of scanner) but may be intermittent depending on where
the film is placed on the bed. When the panoramic X-ray is turned to a horizontal position
where it is sticking out the side of the scanner, the scanned image appears normal on the
monitor but is clipped. The film must be repositioned on the glass in order for the scanner to
capture the rest of the film image; this may require multiple scans.

Reason:

The Perfection 4990 series and V700 / V750-M PRO can scan up to a maximum 8" x 10" film.
Scanning film (whether photographic film or X-rays) larger than the maximum supported film
size is not recommended. For film larger than 8” x 10”, we recommend the Expression
10000XL Photo. This model supports a film size up to 12.2" x 16.5".

When using the Perfection 4990 series and V700 / V750-M PRO to scan larger size X-rays or
any film that does not fit into one of the included conventional size film holders, you must use
the film area guide. The guide properly masks off the allowable film scan area. When placing
film inside the film area guide make sure you do not block the white reference calibration area
on the guide—the notched area at the top of the film area guide is where the scanner performs
its calibration. The scanner takes a transparency white reference calibration reading through
this notched area every time a preview or scan is performed and it must not be blocked or
covered by any part of the film.

When scanning large X-rays or any film larger than 8" x 10" it may be necessary to scan the
film as 2 or more images, so that the white reference calibration area does not get covered by
the film. If you can place the film slightly lower than the white reference calibration area and do
not mind a slight crop of the image then you should be able to scan it as one image. For proper
or complete scans as 1 image, we again recommend that a larger film scanner be used.

The Expression 1600 / 1680 series do not have this issue using the same size film or X-rays
because the TPU supports letter size (11" x 8.5") film scans. The Expression 1600 / 1680
series also have a white reference calibration reading area for film, but it is above the
document bed area, and is less susceptible to this issue as customers generally do not cover
the white reference calibration area on these models. If transitioning from the Expression
series to the Perfection series, it is highly recommend that the user carefully read the film
scanning sections in the Perfection series User's guide.

If you are having issues scanning large film or X-rays on the Perfection series, please verify
you are placing the film properly on the glass and are using the film area guide.

Instructions and Examples:

In Epson Scan use "Professional Mode” and "Film - (with Film Area Guide)" as your Document
Type. X-rays are typically scanned as "Positive Film" film type.

Below is the Film Area Guide for the Perfection 4990 Series / V700 / V750-M PRO scanners.
This image shows the proper placement of a panoramic dental X-ray, where the film is placed
below the notched area and does not cover any part of the white calibration area.
