DocuPen Scratch Removal Procedure

The DocuPen uses contact image sensors to capture the information you would like to

scan. In case you accidentally scratch the lens surface or dust particles enter within the

lens the scanned image could have a distortion in the location of the scratch.

If the Auto Color Calibration procedure does not solve the problem completely then you

can refer to the Manual Scratch Removal procedure.

The Scratch Removal procedure allows you to manually enter the scratch, dust or dead

pixel(s) location(s) so the DocuPen can correct the distortion.

In order to be able to edit the Scratch list you need to perform an image scan in

tion 200

dpi. Open the scanned image in Microsoft Paint (standard Windows OS appli-

cation) and place your mouse cursor on the location of the distortion. In the lower right

corner of the Microsoft Paint window you will then see the precise {x,y} coordinates of

the error pixel location in the format e.g. {135,50}. If the distortion covers more than one

pixel please note all error locations.

In the Edit Dust&Scratches dialog window that

appears please enter the error pixel {X} coordinate, e.g. if

the error pixel location is {135,50} enter {135}.

When you enter all error pixel locations please click OK.

Note:

a time and a maximum of 128 in total.

Finally, click Upload Values button in the Calibration dialog window to send the values

result to the DocuPen. You will be prompted to turn the DocuPen ON. Turn ON the scan-

ner and click OK in the dialog window.

Note:

Your DocuPen must be

Perform another test scan to test if the distortion has been corrected. In case there are

still some inaccuracies please perform the procedure again.

Points to Remember Before You Scan

What you scan is what you get. The DocuPen is sensitive to changes in direction and

scan speed and records every movement you make. The more uniform your scan swipe,

the better your scanned image results. This may take a little practice at first. Scanning

too quickly or abruptly changing acceleration causes the

you to reduce your scanning speed. To obtain the best scan results, note the following:

Hold document

resolu-

The document you scan must be well supported on a smooth flat surface. It is recom-

mended that you hold the top of the document with one hand while you scan with the

other. Place the DocuPen just above the area you want to scan, with the LEDs on the

left side of the document to be scanned.

Press the Power ON button, select the desired color and resolution settings and slowly

glide the DocuPen down across the area you want to scan. The unit begins scanning as

soon as you start moving the pen. When you stop moving, the scan light (at the bottom

of the pen) shuts off and the DocuPen saves the data. You must wait momentarily till the

data is stored in memory. The DocuPen will then automatically shut off.

Do Not tilt

Remove staples or clips as they will impede the glid-

ing movement and the resulted scan will be distorted.

Apply even pressure, in the center of the scanner to

allow the rollers to rotate smoothly.
