Problem: The scanned images are of poor quality even after I recalibrated and cleaned the scanner.

Try reinstalling the scanner driver. The driver software may have been corrupted.

STATUS LIGHT TROUBLESHOOTING

The status light indicates the current state of the scanner:

• Steady blue—indicates the scanner is receiving power. When the scanner driver is installed, it also means

the scanner is ready to scan.

• Blinking blue—indicates that the scanner is busy (e.g. when scanning or calibrating).

• Blinking red—indicates that there is a hardware error.

ERROR CODES

If your scanner experiences a hardware error, the status light will blink red. It will flash in a numerical sequence,

pause, then repeat the same number of flashes. The number of times the light blinks between pauses indicates

the error code number. The following table describes the error codes.

Error Code Problem Description Solution

4 Paper jam Open the scanner and remove the jammed document.

To reduce the number of paper jams, make sure the

paper return is closed when scanning thick documents

and plastic cards. Also make sure the paper guide is

properly adjusted to the width of the item you are

scanning. If the paper guide is too narrow for the paper

being scanned, it will cause the paper to warp and get

stuck in the paper path.

6 Cover open Make sure the scanner is fully closed after performing

maintenance on the scanner or removing a jammed

page. If needed, open and close the scanner again. If the

problem persists, try power cycling the scanner through

un-plug and re-plug of the USB cable.

8 Calibration error This may occur if the USB cable was unplugged during

calibration, the calibration was canceled, or the

calibration page was not used.

First, power cycle the scanner through un-plug and re-

plug of the USB cable, and then restart the calibration

routine. Please refer to Calibrating Your Scanner on

page 172 for instructions.

Make sure you have the scanner’s calibration page ready

when you start the calibration utility.
