Epson Perfection 4990 Photo Product Support Bulletin(s) - Page 2

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.
