Page 11: Scanner Properties
2.1 Scanner Properties The Scanner Properties window allows you to specify how documents are to be scanned. This includes setting the resolution, page orientation, color preferences, and whether documents are scanned in simplex or duplex mode. 2.1.1 Source The Source drop-down list is used to select how the document is to be fed into the scanner. If Flatbed is selected, documents are scanned from the glass and can only be scanned single-sided. -
Page 12: Paper Size
2.1.4 Paper Size Use the Paper Size option to specify the size of the documents to be scanned. Refer to the Trūper Operator Manual for a list of page sizes. 2.1.5 Orientation The Orientation section is used to specify the layout in which the documents scanned are to be displayed on the computer screen. -
Page 13: Sides
2.1.11 Sides This section allows you to choose if your documents are scanned single-sided (one side only) or duplex (front and back). Note When ADF and Duplex are selected, both sides of the document are scanned, but the top loaded side is output to the PC first followed by the back side. -
Page 14: Page Layout
2.2.1 Page Layout The Page Layout section has the same functionality as “2.1.5 Orientation” on page 12. However, setting the Page Layout here overrides the Orientation setting on the Scanner Properties window. 2.2.2 Feed The Feed section allows you to choose which edge of the document is to be fed first in the ADF (Automatic Document Feeder);... -
Page 15: Detect Double Feed
2.3.2 Detect Double Feed This function detects the feeding of more than one sheet at a time. Ultrasonic waves are aimed at the document to detect double feed by the level at which the waves pass through the sheets. This function can detect double feed even when sheets are superimposed exactly on top of each other, but it may not detect properly with some paper thicknesses and when creasing and other factors are present. -
Page 16: Manual Feed Mode
2.3.6 Manual Feed Mode Manual Feed mode allows you to choose how documents are fed to the scanner. Note Scanning does not stop if the application does not come with a cancel function.

Page 18: White Level From Paper
2.4.2 White Level From Paper This function uses white as the reference for the background colors of documents being scanned. When a document with a colored background other than white is scanned, the resulting images contain a lot of noise. This is because the texture of the paper is scanned, however, when the White Level From Paper function is set to On, the texture is ignored resulting in clear images and text. -
Page 19: Gamma
2.4.7 Gamma This function selects the gamma curve (shading adjustment curve). The settings available for the gamma curve are Normal, For CRT, User Download and Linear, which are described in detail in Table 3, "Gamma Settings".

Page 35: Page Size
3.4.2 Page Size Use the Page Size option to specify the size of the documents to be scanned. Note Changing the page size initializes the “3.4 Scan Area” “3.5 Sub Area”. Ensure that the Page Size and Feed properties are set before adjusting the Sub Area. 3.4.3 Page Layout The Page Layout section is used to specify the layout in which the documents scanned are to be displayed on the computer screen. -
Page 36: Sub Area
3.5 Sub Area The Sub Area function enables separate scanning conditions to be set in one part of the scanning range. For example, if there is a region of the document that consistently contains a color graphic, you can achieve better scanning results by specifying the whole page in Black and White mode and then specifying the photo area as a Halftone. -
Page 37: Dither
3.5.2 Dither The Dither mode is primarily used for black and white photographs. It accelerates scanning speed by choosing one of the five preset dither patterns described in “3.1.3 Dither” on page 3.5.3 Brightness For information on the Brightness property, refer to “3.1.4 Brightness”... - Page 38 More than one image filter can be set at a time.
