Understanding SCSI Connections Read the following sections to determine how to set up your SCSI devices. SCSI Chain The SCSI interface allows you to connect up to seven devices (such as a scanner, hard disk, CD-ROM, and so on) to the computer. Only the first SCSI device in the chain is connected to the computer; each of the other devices is connected to another SCSI device.
SCSI Cables The cable you use to attach the scanner to your computer must not exceed 9.8 feet (3 meters). If you are connecting multiple SCSI devices to your computer, you may need to purchase several SCSI cables before setting up your SCSI chain. Be sure the SCSI cable connectors are suitable for your hardware, depending on the maker of your SCSI device and SCSI interface board. To connect the scanner to another SCSI device, the length of cable must not exceed 19.
SCSI Termination Remove the terminator plug or turn off the termination switch for any devices in the SCSI chain other than the first and last device. The first device and the last device in the chain (not including the adapter) must be terminated, either by a terminator plug or a termination switch set to ON. No other device in the chain can be terminated. The EPSON Expression 800 has a termination swtich which is located at the rear of the scanner. The default position of the termination switch is ON.
Setting the SCSI ID Number Make sure the scanner is turned off before changing the SCSI ID number. Do not set the SCSI ID to an ID number that is already assigned to another device. Otherwise the computer, scanner, and other devices will not operate properly. The scanner’s default SCSI ID number is 2. If you add the scanner to a system in which one of your SCSI devices already uses SCSI ID 2, you can change the ID number to an unused number using the rotary switch at the rear of the scanner.

Loading Paper in the Auto Document Feeder The ADF can hold up to 30 sheets of the following paper sizes, based on a paper weight of 17 lb and a thickness of 0.2 inch (6.0 mm) or less: Do not feed photographic sheets or valuable original artwork into the ADF; misfeeding may result in accidental wrinkling or damage to your original. Also, photo quality and glossy paper are too thick to feed into the ADF successfully. Checks: 3 × 5 inches (76 × 127 mm) B5: 7.17 × 10.1 inches (182 × 257 mm) A4: 8.27 × 11.
Follow the steps below to load paper in the ADF: 1 Slide the edge guides all the way out. For checks, move the left edge guide toward the center until it stops, then place your checks in the tray. Move the right edge guide flush against the checks. 2 Arrange your stack of originals face up, with the page you want to scan first on the top. Insert the paper stack into the ADF until it meets resistance. Make sure that the side you want to scan is facing up.
3 Slide the edge guides to the edges of your paper. When scanning high-quality color or halftone documents, it is best to open the ADF and scan documents as described in Loading documents manually. Don’t open the ADF while scanning. You’ll get an option error and possibly a paper feeding error. 4 Follow the steps in your electronic EPSON TWAIN Pro User’s Guide to scan your document. Loading documents manually You can load documents manually while the ADF is installed.
Fixing Paper Jams in the Auto Document Feeder If there is a paper jam, open the ADF’s cover to see where the paper jam occurred. Pull the jam-release lever forward and slowly pull the jammed paper out of the feeder mechanism. Be careful not to pull too hard on the paper. It may tear, making it more difficult to remove.
Maintaining and Transporting Your Scanner This chapter gives tips on caring for your scanner and preparing it for a move.
Cleaning the Scanner Never open the scanner case; doing so will void your warranty. If you think repairs or adjustments are necessary, consult your EPSON Customer Care Center. To keep your scanner operating at its best, you should clean it periodically. Before cleaning it, turn the scanner off and unplug the power cable. Then clean the outside with mild detergent diluted in water. If the glass of the document table gets dirty, clean it with a soft, dry, lint-free cloth.
Replacing the Fluorescent Lamp Never open the scanner case; doing so will void your warranty. If you think repairs or adjustments are necessary, consult your EPSON Customer Care Center. The luminosity of the fluorescent lamp declines over time. If the lamp breaks or becomes too dim to operate normally, the scanner stops working and both the READY and ERROR lights flash. If this happens, the lamp assembly may need to be replaced.
Transporting the Scanner If you need to transport the scanner or store it for an extended period, you must secure the carriage beforehand. If the scanner is inoperable, the carriage may not automatically return to the home position. If it doesn’t, slowly raise the front of the scanner and hold it up until the carriage comes to rest in the home position (at the back of the scanner). Then slide the transportation lock to the LOCK position. 1 Make sure the transportation lock is in the UNLOCK position.
6 Slide the transportation lock to the LOCK position.
Transporting the Transparency Unit After you’ve removed the transparency unit from the scanner, prepare it for shipping as follows: 1 Slowly raise the front of the transparency unit to allow the lamp assembly to slide to the home position at the back of the unit. Wait until the lamp assembly comes to rest.
2 Reinstall the unit’s shipping screw in the hole marked CLAMP.
Troubleshooting This chapter helps you solve scanner problems. It includes the following sections: ◗ Diagnosing Problems ◗ Upgrading Your System ◗ Problems and Solutions Diagnosing Problems Some problems can involve your software or computer, such as: ◗ Incorrect setup of the SCSI interface ◗ Inappropriate selection of the scanner functions ◗ Incorrect setup of your computer or software ◗ Incorrect operation of your scanner software If an error occurs, check the scanner’s indicator lights.
Indicator Lights If an error occurs, the scanner stops operating. The READY and ERROR lights indicate the type of error. ERROR light READY light Error type On On Command The scanner has received incorrect commands from your error scanning software. Try rescanning the document. If the error still occurs, try restarting the scanner. Solution Flashing Off Interface error The interface setup is wrong or the scanner is not properly connected to the computer. Check the interface connection.
Upgrading Your System To improve your image processing speed and the appearance of the images on your monitor, you can add the following items to your system: ◗ Additional memory. Scanned images use much more memory than text files, so you may need more RAM in your computer and a larger hard disk. ◗ Processor. You may want to increase your system’s processing speed; large files take longer to process than small ones. ◗ Video card.
Problems and Solutions Check these sections for the problem you’re having and for possible solutions: ◗ Operation Problems ◗ Scan Quality Problems ◗ Image Matching Problems Operation Problems The OPERATE light does not come on. Problem Solution The scanner is not getting power. Make sure the power cable is correctly plugged into the scanner and the power outlet. Make sure the outlet is operational and is not connected to a timer or switch. The READY light does not come on.
The scanner does not start scanning. Problem Solution The scanner is not ready to scan. Wait until the READY light is on. Your software or interface is not operating properly. If you’re running Windows, make sure you selected the SCSI interface port when you installed your scanner software. Also, make sure the SCSI interface board on your computer is installed properly. See Setting Up and Using Your Scanner for details. Confirm that the terminator and SCSI ID are set correctly.
Scan Quality Problems The entire image is distorted or blurred. Problem Solution The document is not placed correctly. Make sure the document is placed flat on the document table. You may have accidentally moved the document during scanning. Check the position of the document and don’t move it while the scanner is operating. Be sure the scanner is not tilted or placed on an unstable surface. Part of the image is distorted or blurred.
The edges of the document are missing from the scanned output. Problem Solution The document is positioned incorrectly. The document table has non-readable areas around the edges. Reposition your document so that the image you want to scan is within the readable area. Color is patchy or distorted at the edges of the image. Problem Solution The document may be letting in external light. If the document is very thick or warped at the edges, the edges of the image may be discolored.
The image is too dark. Problem Solution Your software settings may be incorrect. Adjust the brightness setting in your software. Also check the brightness and contrast settings of your monitor. Straight lines in the image are jagged. Problem Solution The document may be placed at an angle on the document table. Align it so that the horizontal and vertical lines are carefully aligned with the scales on the top and side of the document table. Scan resolution may be set too low.
The image cannot be printed, the printout is garbled, or the printout is not an image. Problem Solution Your printer may be causing the problem. Check that the printer is properly connected to the computer and is correctly set up. (See your printer manual for instructions.) Your printer software may be causing the problem. Check that your printer software is properly installed and configured. (See your software manual for details.) Color stripes appear when scanning film.
Image Matching Problems The image does not look the same as the original. Problem Solution Your application software settings may be incorrect. Try different image settings in your scanner software. (If you’re using EPSON TWAIN Pro, first try changing the Destination to see if your problem may be screen or printer calibration.) Your application may not have sufficient color matching and color management features, or these components of your software may not be correctly installed.
Colors on your monitor are different from those in the original image. Problem Solution You’re using EPSON TWAIN Pro and didn’t calibrate your screen to the scanner. Use the EPSON Screen Calibration utility as described in Setting Up and Using Your Scanner. Your scanner software settings may be incorrect. Check the image settings in your scanner software, especially data format (bits/pixel/color), gamma correction, and color correction. Try a different combination of these settings.
The printed image is larger or smaller than the original size. Problem Solution You may have adjusted the image size settings in your scanner software. Change the image size settings in your scanner software to resize the scanned image. Don’t use the size of the image on your monitor to judge the printed size. The colors of the preview for your negative film image look strange. Problem Solution The wrong Document Source setting is selected in your EPSON TWAIN Pro software. Make sure TPU for Neg.
