Scanning Thick Media

6. Scanning Thick Media
Many industries, such as reprographics and GIS, will find the need to digitize or copy images
printed or pasted on thick media such as cardboard, foamboards, gatorboards etc. To support
such needs you can change the vertical size of the insertion slot (pressure-platen height) on
your scanner to fit the slot to the thickness of your original. Depending on your scanner model,
adjusting the pressure-platen's height is either a manual or automatic process.
6.1 Adjustment for Thick Media – Slider Controls
On Scanners:
You can manually change the insertion slot size (pressure-platen height) on your scanner from
2mm to 15mm (up to 0.6") so you can fit the slot to the thickness of your original. Originals up to
2mm thick should be scanned with the Normal (2mm) setting. Thicker originals will require
adjustment for thick media.
Adjusting the insertion slot for thick media – Normal Method – For all original types:
1. Measure the thickness of your original to find the right setting.
2. Insert your fingers in the insertion slot and lift to open the scanning area lid.
3. The thickness adjustment sliders are on right and left sides of the pressure-platen.
4. The slider is divided into a Normal position and Extended positions.
5. The Extended settings are marked in inches and millimeters. Each step marks an
interval, i.e., the 4 setting means documents from 2mm to 4mm etcetera.
6. The round metal button indicates the current setting (see illustration below). For paper
thin originals this will be on the 2mm (0.08") setting – also called the "Normal" setting.
7. Press down on the right slider and move inwards (towards middle of scanner) to the
correct thickness setting.
8. Press down on the left slider and move to the same thickness setting as above.
9. Close the scanning area lid.
10. Feed your thick original. The Paper Ready key will turn yellow (stop blinking) when the
pressure-platen is positioned correctly and is ready to scan your thick original.
Quick method –for stiff and thick originals only:
You can use the following Quick method for stiff and hard surface originals. This method is not
recommended for soft or flexible media such as originals mounted on foam boards, as there is a
high risk for creating an over-tight insertion slot and causing damage to the original.
1. Insert your fingers in the insertion slot and lift to open the scanning area lid.
2. The thickness adjustment sliders are on right and left sides of the pressure-platen.
3. Press down on the right slider and move inwards (towards middle of scanner) to the
highest setting, the 16mm (0.63") mark thickness setting. Repeat with the left slider.
4. Slide the original into the insertion slot and under the pressure-platen.
5. With both hands, press down gently on each side of the pressure-platen until you feel it
contacts the original underneath and the sliders adjust themselves to the proper height.
6. Be sure to control that both sliders (on each side) are set to the same thickness value. If
not, adjust the sliders so they are.
7. The Paper Ready key will turn yellow (stop blinking) when the pressure-platen is
positioned correctly and is ready for thick media scanning.
