Unpacking the Scanner This chapter describes how to set up and test your scanner. When you unpack the scanner, make sure that you have all the parts and that none have been damaged. In addition to this User’s Manual and the Epson Color Image Scanner Image Samples booklet, you’ll find these items: Scanner main unit Power cable After removing the parts, save the packing materials in case you need to transport your scanner.
Choosing a Place for the Scanner Keep the following in mind when selecting a place to set up the scanner: l l . . l . l Place the scanner on a flat, hard, stable surface. Place it close enough to the computer for the scanner cable to reach. Leave adequate room around the scanner to allow for easy operation and maintenance. Make sure you can easily place and adjust a document on the scanner. Use a grounded outlet; do not use an adapter plug.
Assembling the Scanner After you’ve found the best place to set up your scanner, the next step is to assemble the parts. Removing the Transportation Screw Before plugging in the scanner, you must remove the transportation screw. This screw secures the carriage mechanism during transport to protect it from damage due to shock or vibration. 0I l CAUTION: Do not plug in the scanner before removing the transportation screw. 1. Place the scanner on a flat, stable surface with the back panel facing you. 2.
Assembling the Scanner 4. Remove the screw by turning it counterclockwise. 5. Insert the transportation screw into the storage hole on the left side of the back panel. Push the screw all the way into the hole; it does not screw in.
Assembling the Scanner 6. Place the stopper over the transportation screw with the round side of the stopper toward the top of the scanner. Note: Do not discard the transportation screw or the stopper. You will need to replace the transportation screw whenever you transport the scanner.
Assembling the Scanner Attaching the Document Cover The document cover keeps outside light from interfering with the scanning process. 1. Place the scanner on a flat, stable surface with the control panel facing you. 2. Hold the document cover perpendicular to its base while holding the base parallel to the scanner. 3. Insert the metal tongues on the base of the document cover into the slots at the back of the scanner. The tongues slide in easily; do not force them.
Scanner Components Now that the scanner is assembled, you can examine the scanner components. Document cover Carriage (at home position Document table The document cover prevents outside light from interfering with the scanning process. Close the cover when you are scanning a document. You can remove the cover to scan bound or thick material. You place the document to be scanned on the document table. The carriage contains the optical sensor and three fluorescent lamps.
Scanner Components The control panel contains indicator lights that show the status of the scanner, and buttons for controlling the brightness, zoom, self test, and direct print features. DIP switches (located under the cover) let you select settings for the direct print function. Serial interface connector onal parallel interface connector You connect the power cable to the power inlet. The transportation screw is shown in its stored position.
Testing the Scanner Now that your scanner is fully assembled, you can use its built-in self test function to see that it is working correctly before you connect it to your computer. You should perform this test to make sure the scanner was not damaged during shipping. Before running the self test, you need to connect the scanner to an electrical outlet. Plugging in the Scanner 0 1. CAUTION: Make sure you have removed the transportation screw before you connect the scanner to a power source. 1.
Testing the Scanner 3. Plug the power cable into a properly grounded electrical outlet. Turning on the Scanner When you turn on the scanner, the POWER and ZOOM lights come on. The display shows 100, which indicates a zoom value of 100 percent. The scanner performs a self-initialization; it returns the carriage to the home position and checks the fluorescent lamps. After a few seconds, the READY light comes on. 0 1.
Testing the Scanner 3. To perform the self test in page sequence mode, hold down @ (Increase) while you turn on the scanner. The carriage makes three passes from the home position to the front of the scanner; first with the green light on, then the red light, and then the blue light. To perform the self test in line sequence mode, hold down @ (Decrease) while you turn on the scanner. The carriage makes one pass from the home position to the front of the scanner using all three lamps.
Connecting the Scanner to Your Computer After testing the scanner, you are ready to connect it to your computer. If you plan to use the ES-300C with an IBM compatible computer, you must install the bidirectional parallel interface board in your computer. You then connect the scanner to the computer using the bidirectional parallel interface. See Appendix B for details on how to do this. If you plan to use the ES-300C with a Macintosh computer, you connect them using the SCSI interface.
Setting Up Your Application Software After connecting the scanner to your computer, you are ready to begin using the scanner. See the documentation that comes with your scanner utility program or interface kit for details on how to use the software.

Operating the Control Panel The ES-300C scanner’s control panel consists of four indicator lights, an alphanumeric display, and three buttons. The control panel shows the current status of the scanner and allows you to start the self test and the direct print function (see Appendix D).
Operating the Control Panel READY (green) On when the scanner is ready to receive commands from the computer software. Flickers during scanning. ZOOM (orange) On when the display is in zoom mode. Use the @ (Increase) and @ (Decrease) buttons to change the zoom value shown on the display when you are using the direct print function. BRIGHT (orange) On when the display is in brightness mode.
Operating the Control Panel @ (Increase) Pressing this button increases the zoom value (in increments of 1%) between 50% and 200% and increases the brightness value in increments of 1 between seven values, from -3 (lightest) to 3 (darkest). Use this button to adjust zoom and brightness only when you are using the direct print function.
Using the Document Table This section tells you about the document table and how to place documents and bound materials in the scanner. The Document Table The document table has an origin mark and scales to help you adjust the document position. You can scan documents of any size up to and including U.S. letter and A4 documents. Horizontal scan 11.7 in. 1 ./ Origin mark (297 mm) Scale I -,418.5 in. (216 mm) Note: There is an unscannable margin around the four edges of the document table.
Using the Document Table Origin The origin, which is the starting point of the scanning area, is located in the upper right corner of the document table as shown in the previous illustration. When placing your document face down on the scanning area, you normally align the upper right comer of your document with the origin. Horizontal scan and vertical scan The direction along the top (shown above by black arrows) is called the horizontal scan.
Using the Document Table 2. Place the document face down on the document table. Adjust the document position using the origin mark and scales. 3. Close the document cover gently to avoid moving the document.
Using the Document Table Note: Make sure that the document is flat against the glass surface so that the image is properly focused. Also be sure to close the document cover to prevent interference from external light. 01 . CAUTION: l Always keep the document table clean. See Chapter 3 for information on cleaning the scanner. l l l Avoid twisting the document cover when you open or close it.
Using the Document Table 1. Lift up the document cover. Lift the base up and out of the scanner. 2. Place the book on the document table. 3. Push down gently on the book spine so that its surface is flat against the document table.
Preparing Scanner Software For the scanner to operate, it must interact with the computer using various settings for scanning and image data transfer. Therefore, to use the scanner you need a software utility program that enables your computer to communicate with the scanner. To purchase the proper software for your scanner, consult your Epson dealer. Using Application Software The main advantage of using an image scanner is that you can edit the scanned images on a computer.
Scanning an Image Your scanner can accommodate a maximum document size of 8.5 inches x 11.7 inches, slightly larger than U.S. letter size or A4 size. Note: There is a small unscannable margin around the four edges of the document table. See page 2-5. 1. Turn on the scanner and then the computer. Check that the scanner’s READY light is on. 2. Place the document face down on the document table. 3. Close the document cover. 4. Start the scanner software on the computer and scan the image.
Using the Scanner Functions Numerous image processing functions are built into the ES-300C and many can be combined to produce a variety of effects. Note: Do not use DIP switch settings or the control panel to control l scanner functions unless you are using the direct print function (see Appendix D). l l With some scanner software, not all of the scanner functions may be available or the range of settings may be limited. When using application software, see its documentation for details.
Using the Scanner Functions Normally you should choose the setting that matches the resolution of your output device, usually your CRT display or printer. To find a matching resolution, check your software manual or follow the guidelines below.
Using the Scanner Functions Scanning Area Use this function to scan a specific portion of the original image. You can choose a rectangular area anywhere within the maximum scanning area of the scanner as determined by the current resolution and zoom settings. Data Format The data format determines how many bits are used to represent a pixel. A pixel (picture element) is the tiniest area a scanner “reads.
Using the Scanner Functions Monochrome mode (standard) Use this mode when you want to scan a black and white image. If you scan a color image in monochrome, you may need to specify a dropout color to recover or delete detail. See Dropout color below. Standard monochrome scanning uses all three lamps so that the original image is scanned with white light, thus minimizing the dropout color.
Using the Scanner Functions Halftoning mode A Use this mode for scanning most images with continuous tones. This mode produces higher contrast images than mode B. Available for 1 and 2 bits/pixel/color data in all color mode settings. Halftoning mode B Use this mode for images that contain large areas of similar tones. The image is converted to soft tones to blend each tone into the next. Available for 1 bit/pixel/color data. This mode is not effective when color line sequence is selected.
Using the Scanner Functions Printer output B Use this setting for low density printers, such as 9-pin printers and printers that produce finer dots, such as laser printers and ink jet printers. If your results are unsatisfactory, try Printer output A. Printer output C Use this setting for enhanced contrast and definition when scanning images that contain both pictures and text.
Tips on Using the Scanner This section provides you with some tips and further information for using the scanner. Note: Use these guidelines and your scanner software to obtain better results when scanning and reproducing images. Scanning Line Art and Characters If the line art contains many straight lines, adjust the document position so that lines are aligned with the horizontal scan or vertical scan directions. If it is placed askew, the straight lines will have jagged edges.
Tips on Using the Scanner Transparent document Transparent material may not be scanned properly because the ES-300C scanner scans an image by reflecting light off the document surface. In the case of overhead projector transparencies, if you can clearly recognize the image on a transparency by placing it on an opaque surface, it can be scanned. Film negatives or 35 mm slides cannot be scanned because the images on them are too dark and too small for the scanner to recognize.
Tips on Using the Scanner The Scanning Speed As the amount of image data increases, the time to scan the image and transfer the image data increases. The amount of image data increases as you increase the resolution, data format, zoom, and scanning area. The speed is also affected by the interface transfer speed, computer performance, and software performance.

Using the SCSI Interface This section introduces you to the SCSI interface. If you are unfamiliar with the SCSI interface, be sure to read this entire appendix thoroughly. Introducing the SCSI Interface The SCSI board included in the kit allows you to connect the ES-300C scanner to an Apple Macintosh computer using the industry-standard set of hardware and software specifications known as the Small Computer System Interface (SCSI).
Using the SCSI Interface WARNING: l Before handling the SCSI board, first touch a grounded metal object to release any static electricity on your body that may cause damage to the components of the board. 0 Hold the interface by its edges and the shielding plate. Do not touch the edge connector or the components on the board. 1. Locate the rotary switch on the SCSI board to check or change the SCSI ID. 2.
Using the SCSI Interface 0 I. CAUTION: l l Do not set the SCSI ID (the rotary switch) to 8 or 9. These numbers are not available for SCSI connection. Do not set the ID number to an ID that is already assigned to another device. If two or more devices have the same ID number, the computer, the scanner, and/or the other device will not function properly.
0I . Using the SCSI Interface CAUTION: Do not connect more than two devices with terminators along the SCSI interface. Having more than two terminators connected at one time could cause serious damage to the SCSI devices on the daisy chain.
Installing the SCSI Interface Board You install the SCSI board into the option board slot located on the back panel of the scanner as described below. CAUTION: To connect the ES-300C in the middle of a daisy chain, you must have the terminator resistors removed from the SCSI board by your dealer before installing the board in the scanner. 1. Turn off the scanner and disconnect the power cable and any other interface cables connected to the scanner.
Installing the SCSI Interface Board 2. Remove the three screws that secure the interface slot on the back of the scanner. 3. Remove the interface slot cover, Keep the cover in a safe place for future use.
4. Holding the SCSI board by the shield plate, gently insert the board into the guides of the option slot. You will feel a slight resistance as the board connectors plug into the connectors inside the scanner. Press firmly to secure the connectors. If the board does not fit, do not force it; look to be sure you inserted the board evenly into the connectors. 5. Check that the board’s back panel rests flush against the scanner’s back panel.
Installing the SCSI Interface Board 6. When the board is properly installed, align the shield plate of the SCSI board with the three screw holes on the back panel of the scanner.
Connecting the Scanner to the SCSI Interface This section shows you how to connect the ES-300C to the SCSI interface. Consult your dealer to obtain the proper SCSI interface cable. CAUTION: If you have a Macintosh Plus, you must first set DIP switches SW1-1, SW1-2, and SW1-3 on your scanner to on. (See pages D-4 to D-7 for information on how to change DIP switch settings.) Connecting the Scanner as a Single SCSI Device The simplest connection hooks the computer directly to the scanner.
Connecting the Scanner to the SCSI Interface Connecting the Scanner to Other SCSI Devices If you are connecting more than two SCSI devices in the daisy chain, you need a 50-pin to 50-pin SCSI peripheral cable. follow those guidelines could cause damage to or interfere with operation of the scanner and/or computer. 1. You must place the scanner (containing the SCSI board with an internal terminator) at the end of the daisy chain. The order of connection does not affect the speed of scanning operations.
Connecting the Scanner to the SCSI Interface 3. If you have a Macintosh without an internal hard disk and you want to connect one or more SCSI devices in addition to the scanner, you must be sure the first SCSI device in the chain has a terminator (either external or internal) as shown in the illustrations below. Computer SCSI device Internal terminator LComputer SCSI device - I ES-300C scanner Normally, in this arrangement, the first SCSI device is an external hard disk.
Connecting the Scanner to the SCSI Inferface The Power on Sequence SCSI devices with terminators (the first and last devices in the daisy chain) must be turned on before the Macintosh to allow information to pass through the SCSI interface. The Macintosh may not start up if these devices are not turned on. SCSI devices in the middle of the chain may be left off if you don’t plan to use them at this time.
Removing the SCSI Board When you need to change the SCSI ID or take the SCSI board to your dealer, you must remove the SCSI board from the scanner. 1. Turn off the scanner and disconnect the power cable. 2. Remove the three retaining screws from the back panel of the SCSI board on the back of the scanner. Keep the retaining screws in a safe place. 3. Pull the board straight out using the remover grips. CAUTION: Do not pull the board by the connectors or cables.

About Direct Print The direct print function allows you to use your ES-300C scanner as a color copier if you have an Epson LQ-2500, LQ-2550, or LQ-860 printer with a color ribbon or an HP PaintJet or HP3630 color graphics printer with a parallel interface. With direct print, you connect the scanner directly to your printer and print the scanned image in color. Consult your dealer to obtain the special parallel interface cable required for the direct print function.
About Direct Print Note: l l l l This function does not work properly with monochrome (noncolor) printers or 9-pin color printers. With an Epson 80 column printer or an HP PaintJet, the full scanning area of the ES-300C cannot be printed the same size as the original. This function cannot be used with an HP PaintJet printer that has an HP-IB interface or RS-232C interface. See the printer user’s manual for details on your printer’s operation.
Using the DIP Switches The ES-300C has two sets of DIP switches located under the DIP switch cover to the left of the control panel. Change DIP switches in the following cases: l If you have a Macintosh Plus computer. (See Appendix C.) l When you use the direct print function. l When your software cannot specify the functions that are selectable with DIP switches. (See your software manual.
Using the DIP Switches The values corresponding to the above factory settings are as follows: Baud rate: 9600 bps Stop bit: 2 bits Parity check: None Printer type: Epson 24-pin color printer (80 column) (for the direct print function only) Halftoning mode: Halftoning mode A Gamma correction: CRT Display A Color correction: CRT Display Parallel interface: Bidirectional Changing the DIP Switch Settings 1. Turn off the scanner and remove the DIP switch cover by sliding it toward you.
Using the DIP Switches 2. Use a pen, tweezers, or other pointed object to change the DIP switch settings. A DIP switch is on when it is away from you and off when it is toward you. 3. Replace the DIP switch cover, Note: The new DIP switch settings take effect when you turn the scanner on. Changes you make to DIP switch settings while the scanner is on will not be effective until you turn the scanner off and then back on. The DIP Switch Tables The tables below show the settings for each DIP switch.
Using the DIP Switches DIP switch 1 settings DIP switch 1 determines the serial interface protocols and the direct print function. Table 2. DIP switch 1 settings See table 2. Table 2.
Using the DIP Switches Table 3. Printer type for direct print 1 ON 1 ON Epson LQ-2500 or LQ 2550 (with color ribbon) I DIP switch 2 settings DIP switch 2 determines the scanner operation normally required for the direct print function. For normal scanning operations, your scanner software sets these scanner functions and overrides the current DIP switch settings. Therefore, except for the direct print function, you are unlikely to change these switches from the factory settings. Table 4.

Preparing for a Direct Print Operation Before starting the direct print function, you need to make the appropriate settings on the scanner and the printer as described below, then connect them with a suitable parallel interface cable. Consult your dealer to obtain the proper parallel interface cable. Scanner Settings On the scanner, you have to set the interface direction, printer type, and scanning functions with the DIP switches.
Preparing for a Direct Print Operation CAUTION: l l l Be sure to change SW2-8 to on. This changes the signal direction of the scanner’s parallel interface, which must be set to unidirectional for the direct print function. After a direct print, be sure to set SW2-8 back to off. Otherwise the scanner does not work properly with the computer. Do not use the LQ-2500 or LQ-2550 printer setting when using an 80 column printer.
Preparing for a Direct Print Operation The recommended settings for Epson impact dot matrix color printers are as follows: Gamma correction SW2-3 SW2-4 SW2-5 Printer Output A OFF ON OFF Color correction SW2-6 SW2-7 Impact dot matrix printers OFF OFF The recommended settings for the HP PaintJet color printer are as follows: Gamma correction SW2-3 SW2-4 Color correction SW2-6 SW2-7 Ink jet printers OFF ON SW2-5 1 Printer Output A Note: For explanations on halftoning mode, gamma correc
Preparing for a Direct Print Operation 2. Turn on the scanner. The zoom mode is in effect and the display indicates 100%, the default zoom setting. 3. Press @ to increase the image size or 0 to decrease the image size. The size range goes from 50% to 200% in 1% increments. Note: @ and 0 on the control panel set the same values for both the horizontal scan zoom and the vertical scan zoom. 4. To select brightness mode, press the ZOOM/BRIGHT button.
Preparing for a Direct Print Operation If you are using an Epson LQ-860 printer, use the printer's DIP switches to select unidirectional printing for better results. See your printer’s manual for details on how to set these values. Note: If you have changed the DIP switch settings or the interface type with SelecType, turn the printer off and back on to reset the printer’s defaults.
Preparing for a Direct Print Operation Paper Size and Printable Size The maximum printable sizes available with the direct print function are as shown below. Epson (80 column) and HP PaintJet 1416 dots (7.1 inches or 200 mm) 1680 dots (9.3 inches or 237 mm) I Maximum printable size (Printed at 180 dpi) Epson (136 column) 1744 dots (9.
Starting a Direct Print Operation To start a direct print operation, follow the steps below: 1. Turn on the printer and then turn on the scanner. Note: If the scanner is turned on first, its control panel may display an error message indicating that the scanner cannot detect the interface signals correctly. To return the scanner to normal, turn off the scanner and go back to step 1. 2. Make sure that the printer has paper and is on line (ON LINE light is on) and ready to print.
Starting a Direct Print Operation 5. When the scanner has finished scanning the image, its carriage returns to the home position and the READY light comes on. Note: l l Because the printer is much slower than the scanner, the scanner occasionally stops scanning to allow the printer to catch up. Direct printing with a zoom setting of 100% takes about 7 minutes. At 50%, it takes about 5 minutes. 6.
Tips for Direct Printing This section provides information that may help you in using the direct print function. Terminating a Direct Print Operation Direct printing does not stop until the whole of the scanning area is scanned or the scanner is turned off. When the printer is set off line or runs out of paper, the scanner stops sending data. To resume printing, set the printer on line or load more paper.
Tips for Direct Printing As the zoom value increases, the percentage of scannable image decreases. If, for example, you have an 80 column printer and you are using direct printing, you must set the zoom value at 80% or less to scan and print an entire image. If you scan with a zoom setting of 100% with an 80 column printer, the scanner crops the right side and bottom of the image. The relationship and approximate values of the scannable and printable sizes are shown in the tables below.
Tips for Direct Printing 136 column printer (Epson 136 column) Scannable size inches (mm) Zoom Number of dots scanned Printable size inches (mm) 50% 8.5x11.5 (215x291) 760x1032 4.2x5.7 (107x146) 60% 8.5x11.6 (215x294) 912x1248 5.0x6.9 (128x176) 130% 7.5 x 9.1 (189x232) 1744x2136 9.7x11.9 (246x301) 140% 6.9 x 8.5 (176 x 215) 1744x2136 9.7x11.9 (246 x 301) 150% 6.5 x 7.9 (164x201) 1744x2136 9.7x 11.9 (246x301) 160% 6.1 x 7.4 (154x188) 1744x2136 9.7x11.9 (246x301) 170% 5.
Tips for Direct Printing Scanning Line Art and Characters Line art and text characters usually do not consist of continuous tones and do not require the halftoning process. The following settings are recommended for scanning line art. Data format: 1 bit/pixel/color (bi-level) Halftoning: Disabled Gamma correction CRT Display A If the line art contains many straight lines, adjust the document position so that lines are aligned with the horizontal scan or vertical scan directions.
Tips for Direct Printing If Direct Print Does Not Work This section discusses typical problems and offers possible solutions about operation of the direct print function. The problems you may encounter while using the direct print function often involve inappropriate selection of the scanner functions and/or operation of your printer. See your printer documentation for possible solutions. Problem Solution Direct print does not start or doesn’t work as you expected.
GLOSSARY baud rate A measure of the speed of data transmission. Usually equivalent to bits per second. bi-level data Image data that uses 1 bit per pixel. A single bit of digital data that can express only 1 (light) or 0 (dark) represents a pixel. bit A binary digit (0 or 11, which is the smallest unit of information used by a computer, scanner, or printer. bit/pixel Indicates the number of bits allocated for a pixel. The larger the value, the more detailed the pixel.
default A value or setting that takes effect when the equipment is turned on, reset, or initialized. document The physical material, such as a sheet of paper or a book, containing the image you wish to scan. dpi Dots per inch. A unit of measurement for resolution. The higher the value, the higher the resolution. dropout color The color recognized by the scanner to have the same luminosity as white; therefore it is not scanned.
ink jet printer A printer type that transfers ink onto the paper by spraying it through a number of small nozzles. interface Hardware, method, or standard used for connection between or among computer devices. laser printer A type of printer with an imaging system driven by a computer that allows the printer to compose an entire page in internal memory before printing. line sequence A type of color scanning in which the image is separated into colors line by line.
pixel Short for picture element. Each pixel is comprised of units of dots, and an image is composed of a number of pixels. plain bi-level The bi-level image data without the halftoning process. port A channel or interface through which data is transmitted between devices. quad-level data Data that consists of two bits per pixel and can express four light to dark levels: 00 (light), 01, 10, and 11 (dark). resolution Indication of how finely an image is resolved into pixels.
