 CHAPTER 3 LOADING A DOCUMENT
3.1 Compatible Document Types
Because the scanner scans a document while feeding it, the document types that it can scan are
subject to the following restrictions.

Compatible Media Widths for Scanning

Documents with a maximum width of 965 mm
Size ISO Size ANSI
A4 210 x 297mm A 8.5 x 11in
A3 297 x 420mm B 11 x 17in
A2 420 x 594mm C 17 x 22in
A1 594 x 841mm D 22 x 34in
A0 841 x 1189mm E 34 x 44in
Note: An A4-size document can only be loaded in Landscape (horizontal) orientation.

Compatible Media Lengths for Scanning

Documents up to approximately 16 m in length can be scanned.
However, the actual document length that can be scanned is limited by the available memory
(hard disk or other data storage device) of the computer to which the scanner is connected,
and also by the grade of the document being scanned.

Compatible Document Thicknesses for Scanning

The SK200-09 cannot scan a document that is thicker than 0.8 mm.
When using the carrier sheet that is available as an option, ensure that the combined
thickness of both the document and carrier sheet does not exceed 0.8 mm.
Moreover, documents of an uneven thickness cannot be scanned.
Note: The carrier sheet alone is 0.2 mm thick.

Compatible Media Grades and Thicknesses for Scanning

Media Grades
• The scanning precision is guaranteed for the special chart (Mylar) used in the test (see
APPENDIX B, “SPECIFICATIONS”).
• The compatible media types are listed below.
♦ High-grade paper: 60 g/m2
♦ Tracing paper: 50 to 55 g/m2
♦ Mylar: 50 µm
♦ Copy paper
♦ Diazo photo-sensitive paper
Be sure to use the carrier sheet that is available as an option when scanning a document
where the ink or toner comes off when it is rubbed. If the carrier sheet is not used, there is a
risk of the document feed path becoming stained, and causing subsequent documents to
become stained as well.

3-1
3.2 Loading a Document

How to use the document guides

Insert the document (the surface to be scanned) face up into the scanner until the top edge
of the document contacts the feed rollers. At this time, make sure that the document is
straight and that it is centered in the scanner.
(1) With the top cover in the closed status, turn on the scanner’s power supply.
(2) Move the document guides to the left and right until they are adjusted to the document width.
(3) Place the document between the document guides, and then insert the document into the
gap between the top cover and the document-scanning table, making sure that it is straight.
(4) When the preset delay time specified in the driver software has elapsed, the rollers start
turning to automatically feed the document to the position to start scanning. The
document is now loaded.
(5) After the document has been loaded, move the document guides back to the position
where the Document edge dotted lines can be seen. If the guides are not moved, the
document may get damaged if it is fed at an angle.

If you want to reload the document, press the [EJECT] key to eject the
document. Reload the ejected document.
When the document has been loaded, the [PAPER] LED (green) lights.

Checkpoint If the PAPER LED does not light after the document feed operation has stopped,
press the EJECT key to eject the document.

Caution • If the document is inserted at an angle, the image may be scanned in at an angle
or a scanning error may occur. Make sure that the document is aligned with the
document guides when it is inserted.
• When the scanner has been turned on, the automatic feed operation starts after
the specified interval of approximately three seconds has elapsed.
• Load the document in the scanner with the surface to be scanned face up.
• Do not place anything other than the document to be scanned on the document-
scanning table. If you do so, the scanner rollers may start rotating, which is
extremely dangerous.
• The document may not be fed in correctly if it is curled. The carrier sheet that is
available as an option should be used for curled documents (see Section 3.5,
“Using the Carrier Sheet” for details).
• Load the document in the center of the scanner, as the document may be fed in
at an angle and not scanned correctly if it is significantly off-center.
• Load the document in the center of the scanner. If it is significantly off-center, the
document may shift and may not be scanned correctly.

3-2
3.3 Handling Documents According to their Material and Thickness
The following problems may occur, depending on the thickness and surface condition of the
document being scanned.

• The document cannot be loaded.

• Scanning of the document stops half-way through.
• The document slips (resulting in displaced images).
• The end of the document is not scanned.
Such problems may be avoided by taking the following corrective measures.
• Lower the scanning speed.
• Support the document at the front and the back of the scanner.

3.4 Distance Correction

Corrections to the distance can be achieved using the driver software. The “Adjust” button on the
TWAIN driver’s “Settings” tab can be used to perform distance correction and adjust the scanning
precision.
The adjustment function must be performed when a scanned drawing needs to approximate the
accuracy of the original drawing closely. (This is for making fine adjustments to the accuracy of the
scanned drawing to suit the quality of the paper being used.) It is not normally necessary to perform
this adjustment.

Adjustment method
Perform the distance correction process according to the type of document to be scanned.
Distance correction can be set in a range of ±1%, which remains effective until the scanner’s
power is turned off. The practice of distance correction necessitates that you measure a
vertical line drawn on the document before following the procedure described below.
(1) Choose a document that has one or more vertical lines drawn on it and scan it at a
resolution of 600 dpi in Portrait (vertical) orientation.
(2) Use a ruler or similar implement to measure the length of the selected vertical line in the
document and classify it as “x” (distance on the document).
(3) Load the saved file into an application capable of measuring and calculating the line
length in the image.
(4) Measure the length of the same line in the image data, and call it value “y” (Distance
Measured After Scanning).
(5) Click on the [Distance Correction] button in the [Adjust] screen to open the [Distance
Correction] screen.

(6) Enter the value “x” (distance on the document) and the value “y” (distance after the scan
has taken place) in this screen The values entered here must be within the distance
correction range (±1%).
(7) Click the [OK] button to calculate the correction value. The distance will be corrected the
next time a document is scanned.

3-3
3.5 Using the Carrier Sheet
Use the carrier sheet according to the condition of the document to be scanned.
In the case of scanning the following types of media, always place the document in the carrier sheet
that is available as an option before loading it into the scanner.

• To scan a document that is smaller than A4 size or a document of non-standard size

• To scan a document that is as limp as or limper than a newspaper
• To scan a document that tears or becomes damaged easily
• To scan a document that is considerably damaged
• To scan a document that is badly creased
• To scan a curled document
• To scan a transparent or translucent document
• To scan a document to which other pieces of paper have been attached
• When the target document cannot be properly advanced to the initial position of scanning
(because the target document is not flat, or otherwise hard to load in the scanner)
• Curled documents with a width that exceeds A2-size (420 mm)
• Fragile documents with a width that exceeds A2-size (420 mm)
As shown in the figure below, place the document in the carrier sheet with the document’s
surface to be scanned face up (against the transparent top sheet). For scanning, load the
carrier sheet into the scanner with the document’s target surface (the transparent top sheet)
face up.
