You can install one of two different interface cards to connect your Epson scanner to your computer: Ll Epson b&directional parallel adapter @3808011), or 3 Adaptec AHA-1510 AT-to-SCSI host adapter. Note Epson TWAIN supports the built-in bidirectional parallel interface on the IBM PS/2. If you have a PS/2, you don’t need to install an additional interface card. Turn to Chapter 2 for instructions on installing Epson TWAIN.
Removing the Cover Follow these steps to remove your computer’s cover: 1. Turn off the computer and any peripheral devices. 2. Disconnect the computer’s power cable from the electrical outlet and from the back panel. Also disconnect any cables that are connected to the computer, including the keyboard cable. 3. Remove the cover. (If you need instructions, see your computer manual.) 4.
2. Locate jumper J1 on the card. (Ignore the J2 jumper.) J1 A jumper’s setting is determined by where the jumper is placed on the pins. It connects either the left pin and the middle pin or the right pin and the middle pin, as shown below.
Refer to the table below to see which setting is appropriate for your system. J1 Jumper settings Position Function LPT2’ Identifies the port address as LPT2 LPT1 Identifies the port address as LPT1 ‘Factory setting Most people use LPT1 to connect a printer, so you probably want to leave the jumper at the factory setting so that it supports the LPT2 address for your scanner.
installing the Card Your computer has several standard option slots that can accommodate either the Adaptec SCSI or the bidirectional parallel adapter card. You can install the interface card in any available slot. See your computer manual for detailed installation instructions or follow these general steps: 1.

If you have problems using Epson TWAIN, check this section. It describes potential problems and provides possible solutions. When you select an Acquire device, Epson Scanners is not listed. Either Epson TWAIN was not installed or was not installed correctly. Reinstall Epson TWAIN using the Setup program from within Windows. Nothing happens when you select Acquire. Make sure your scanner is turned on and the cables are connected properly. Epson Scanners may not be selected as the “Acquire” device.
You may have tried to install Epson TWAIN using the Setup utility for the Adaptec AHA-1510 SCSI Host Adapter when you were using another Adaptec host adapter. The Epson TWAIN SCSI installer installs SCSI support only for the Adaptec AHA-1510 SCSI Host Adapter. If you are using a different adapter, follow the software installation instructions in the adapter user manual. Then run the Epson TWAIN Setup program and select Use Existing SCSI Support Software at the SCSI Interface Options screen.
When you type a value that exceeds the right edge of the scanning area, the value is not accepted. Move the selection rectangle to the left edge and retype the value. An error in the scanner or a paper jam in the Automatic Document Feeder caused an error message. Reset the scanner to clear the error condition, then try scanning again. The Sharpness setting is “grayed out” in the Epson TWAIN Scanner Control dialog. You are using a scanner that does not support the Sharpness feature.
If your application has an INVERT function, use it to reverse the image. The predefined Scan Mode and Target Device settings don’t meet your specific scanning requirements. You can define your own settings using the instructions in Chapter 3 of this manual. Sometimes the halftone or dither settings you select in Scan Mode seem to be ignored.
