Introduction

Features
The EPSON GT-7000/GT-7000 PHOTO/GT-7000 USB scanner offers the following features: Maximum optical resolution of 600 dots per inch (dpi) for main scanning, and 2400 dpi with micro step for sub scanning (36-bit input, 24-bit output). Start Button control for shortcut scanning operation. Light body with A4/Letter size scanning area. Full color or grayscale scanning. Capture your images with 256 colors, or over 16 million colors; or up to 256 shades of gray. EPSON Scan! II scanner utility and EPSON TWAIN let you take full advantage of your scanner's advanced features. Auto Area Segmentation (AAS) allows you to separate text from photographs on a page so that grayscale images are clearer and text recognition is more accurate. Text Enhancement Technology (TET) enhances text recognition accuracy for optical character recognition (OCR) scanning. EPSON TWAIN's Quality & de-screening option automatically removes unwanted moir patterns from scanned images for higher quality output. The GT-7000 PHOTO includes the Film Adapter which enables negative film and slide film to be scanned. The Film Adapter is available as an option for the GT-7000/GT-7000 USB.

Connecting the scanner
Connect the scanner to your computer or to another SCSI device as follows: Note: The combination of 50-pin and 25-pin connectors you need varies depending on the maker of your SCSI device and SCSI interface board. 1. Make sure the scanner, computer, and all other SCSI devices are turned off and unplugged from the power source.
Caution: Do not connect the scanner to the computer or other devices while they are turned on as damage may occur.
2. Connect one end of the interface cable to one of the scanner SCSI connectors until the locks on both sides snap in.
Note: To connect the scanner to a SCSI device other than the computer, the length of cable in the daisy chain must not exceed 6 meters; otherwise the system may not work properly. To connect the scanner to a PC using SCSI-2, the length of the cable must not exceed 3 meters. 3. Connect the other end of the cable to the SCSI port of your computer or another SCSI device. Note: The SCSI port on the Macintosh is the larger port with the SCSI icon over it. 4. Plug in the power cords of your computer, scanner, and other external SCSI devices. Note: Before turning on your system, be sure to read Power-on sequence following.

Power-on sequence

Keep the following in mind every time you turn on your computer and SCSI devices, including the scanner. Be sure to turn on the SCSI device which is connected at the farthest end of the daisy chain first, then the second farthest and so on, until finally your computer. If you attempt to use a SCSI device which has been turned on after the computer, it may not work properly, or the computer may not work properly. For Windows 95 or 98 users: The first time you turn on the computer after turning on the scanner, one of the following dialog boxes may appear.

Removing the Cover for Thick or Large Documents
For thick materials or documents that are larger than the document table, remove the document cover.
Hold the back of the document cover and lift straight up.
Note: When scanning with the cover removed, do not leave any area of the document table exposed to prevent interference from external light.
When you are finished scanning, reattach the document cover by pushing straight down on the back until it clicks into place.
Caution: Make sure both of the cover's notches are directly above the clips on the scanner before pushing it down into place; otherwise damage may occur.

Sizing Up Your System

Your scanner is sufficient for most scanning needs, but if you are not satisified with the quality of the images on your monitor or with the speed of image processing, read this section. While it does not contain specific recommendations, it describes various possibilities for improving your scanning system. For further information, seek advice from your dealer or an experienced scanner user.

RAM and hard disk size

Scanned images use much more memory than text files, so you may need more RAM (Random Access Memory) in your computer and a larger hard disk than you have used previously.

Accelerator boards

In addition to memory, processing speed is important because large files take longer to process than small ones. Therefore, you may want to add an accelerator board to your computer.

Video cards

A video card that is sufficient for text may not be good enough for displaying graphic images, especially in color. If all your scanned images look coarse on your monitor, you may want to upgrade your video card. You will need 24-bit color, also called true color or millions of colors, to make the highest quality image reproductions.

Monitors

The resolution of your monitor affects the quality of the image you see. Consider a high resolution monitor if you do precise color work, but also be sure you have a high quality video card.

Caution: Hold the film at the edges, or else use gloves. Touching the film surface with bare hands can leave fingerprints or other traces on the film.
Note: The base side of the film is the side which the film makers name and film ID numbers are shown.
35 mm negative or positive film
Insert a strip of film in the 35 mm film holder, base side facing down.
120/220 (6 cm x 9 cm) film
Insert film in the 120/220 (6 cm x 9 cm) size film holder, base side facing down.

4 x 5 inches film

Insert film in the inch film holder, base side facing down.

Loading slides and film

You can scan slides and film strip in the inch (101.mm) scanning area of the Film Adapter. Note: Wipe the inside of the Film Adapter cover, the scanners document table, and the narrow window near the hinges before scanning transparencies. You need to select TPU for Neg. Film or TPU for Pos. Film in the Document Source settings in EPSON TWAIN depending on the type of film (negative or positive) you are scanning. The scanner software automatically controls the operation of the Film Adapter. Follow the steps below to load film or slides.
1. Open the top of the Film Adapter, holding the base down.
2. Load the transparency to be scanned face down on the scanners document table in the window of the Film Adapter as shown below. If you are scanning 35 mm strip film, use the 35 mm film holder to set the film.
If you are scanning slides or transparencies which will not fit in the film holders, place them directly on the document table.
Note: Place the film holder on the document table in alignment with the upper left-hand corner of the Film Adapter. When scanning 120/220 (6cm 9cm) or similar film, use the film holder as shown below.
If the film size is 4" 5" or similar, use the film holder as shown below.
3. Close the unit. Note: Make sure the unit is completely closed, otherwise an option error results and you cannot scan the document, nor attain proper colored images. When previewing images on EPSON TWAIN of negatives scanned using a film holder, the color may appear odd as the frame of the film holder is perceived as white, causing your scans to appear darker. To see the correct color, click and drag the mouse over an area, then click the zoom preview button. You can move and adjust the position of 35mm film by sliding the strips in the film holder so the frames you want to scan are positioned in the window.

To remove a film holder from the document table, slide it left or right then take it out of the window.
Leave the opening shown below uncovered, otherwise the colors in your scans will be affected.

Scanning normal (reflective) documents
When you return to scanning normal reflective documents, you can simply turn off the Film Adapter, then place documents between it and the document table. If you will not scan transparencies for a long time, you can remove the Film Adapter and store it in the original package. Remove the Film Adapter in reverse order as described on page 3-3. Note: When scanning thin documents, you may see an impression of the underside of the Film Adapter in your scans. If so, change to using the document cover instead of the Film Adapter.
Using the Automatic Document Feeder
The Automatic Document Feeder (B81314) allows you to automatically load multiple-page documents into your scanner. This document feeder is particularly useful for OCR (optical character recognition) scanning, or for creating an image database.
Unpacking the Automatic Document Feeder
When you unpack your Automatic Document Feeder, make sure you have all the parts shown below. If any items are missing or damaged, contact your EPSON dealer immediately.

4.5 Notes for SCSI Data block sent by Scanner consists of two parts: an information block and data. The information block includes a Byte-counter word that indicates the length (in bytes) of the data block. In the case of SCSI, since data length should be set in the CDB (Command Descriptor Block) field by an initiator (HOST), the information block and the data are sent separately. The initiator (HOST) receives the information block and detects the byte length of the data, then it receives the data.

[ Download Dither Pattern] (1) Code: ESC b ASCII: decimal: hexadecimal: (2) Function: ESC b i j d(j ) 27,98 i 1B,62 i
Downloads the threshold values of the dither pattern. 2 patterns can be sent to the scanner, and the parameter i indicates their identity. i = 0 : Pattern A, i = 1 : Pattern B The parameter j has the value of 4, 8, or 16, and it indicates the number of pixels for a side of the square forming the basic element of the dither pattern. The data trailing j are the threshold values to be arranged in the dither pattern square. The data is arranged in the order shown in Fig. 1. The total number of items in the threshold data is 2 j. For example when j = 4, then items = 16, when j = 8 then items = 64 and when j = 16 then items = Fig. 1 The order of 256. arrangement of data The threshold data value should range between 0 and 255 because the size of the image data is one byte. Thus, in the case of a spiral pattern of 4*4 square shown in Fig. 2(a), the threshold values should correspond to those in the Fig. 2(b), respectively.
