8 TROUBLE SHOOTING

Lights on scanner control panel fail to come on

~ Check that the power supply is connected to the scanner.

~ Check that the scanner is switched on.

Error symbol on the display panel indicates a failure during power up

~ Scanner needs re-calibrating.

~ Dirt or major scratches seen by scanner during warm up. Clean glass

~ If the fault persists then a service engineer is required.

Streaks appear on the image

~ Dirt or scratch on glass.

NOTE: If the lines are vertical and continuous please recalibrate the scanner first making

sure that the calibration target is as clean as possible.

There is a vertical discontinuity in the image half-way across the scanned image.

~ Carry out the stitch procedure.

There are visible colour artifacts in the image, very noticeable in the horizontal

direction and the scanner stops and starts while scanning.

~ Use the fractional speed function in ScanWorks to slow down the document scan

speed. This will prevent the scanner from pausing while the queued data is written to the

computer’s hard disk. By avoiding scanner ‘stop and start’ during a scan the generation

of artifacts is eliminated.
