READY light is on or flashing.

The green READY light is on when the scanner is ready to scan. It flashes when scanning is in progress.

ERROR light is flashing; READY light is off.

There's a problem with your cable connection. Reconnect the cable to both the scanner and your computer, and then restart your computer. If this doesn't work, try using a different cable. If you have a USB connection, use the USB cable that came with your scanner. If you have a SCSI connection, always restart your computer after changing or reconnecting the cable.

ERROR and READY lights are both on.

The scanner has received an incorrect command from your scanning software. Try rescanning the document.

ERROR and READY lights are both off.

There's a problem with either the transparency unit or automatic document feeder. Make sure your unit lies flat against the scanner. Then reconnect it to the OPTION connector on the back of the scanner. If you have a transparency unit, make sure you removed the shipping screw from the hole labeled CLAMP. Make sure your automatic document feeder has paper and there's no paper jam.

ERROR and READY lights are both flashing.

Check that the transportation lock on the back of the scanner is set to UNLOCK. If not, unlock the scanner, then turn it off and back on again. If this doesn't solve the problem, contact EPSON as described in "Where To Get Help".
