Possible Solutions
Make sure the resolution of the scanner is not set too high.
Set the Parallel Port Mode inside computer's BIOS to EPP.
Check that printer cable is properly secured to printer and scanner.
Make sure printer is turned on.
Turn off the computer and the printer. Make sure that the scanner is
plugged into a constant power source (leave scanner on at all times).
Turn the computer on and enter Windows. Once inside Windows turn on
the printer and try printing a document.
Reset the computer (turn it off and on).
Unplug the power cable from the rear of the scanner and open the
scanner's lid. Looking at the front of the scanner while the lid is open
plug the power cable back into the scanner. If the light turns on and off
quickly, the scanner is properly working.
Check your computer's printer to see if it's an EPP. Enter the computer's
BIOS and check the Chip Set. If the parallel port mode is set at ECP or
SPP, change it to EPP. Save and exit BIOS and run Windows. Enter the
Scanner Utility and click the proper address and EPP. Choose Verify
Port.
The scanner's light source is designed to stay on all the time. To turn off
the scanner's light, enter the Scanner Utility and choose Accessories.
Shorten the printer's cable. Sometimes when information has to travel a
long distance it becomes distorted. Shortening the printer's cable can
decrease the possibility of information becoming damaged.
Upgrade printer port, or controller card to an EPP interface.
Enter BIOS and change the printer port to EPP and its address.
If your system's motherboard uses a UMC8669, or UMC8663 I/O
chipset, then enter the computer's BIOS and change the parallel port
address to 378H and its mode to EPP (enhanced parallel port).
If the above step does not solve your problem, add the following
statement to the SYSTEM.INI file below the heading "[386Enh]:"
PORT_CHIPCONTROL=1
If the power from your A/C outlet is below the necessary voltage
required to properly run the scanner, the scanner's light source will blink
intermittently causing poor scans. Try turning off any unnecessary
appliances and try scanning again.
Look at the Scanner Setup option inside of the application and make sure
the correct scanner is chosen.
Check all connections and make sure they're secure and correct.
