Error Message:

HEAD: Warning - possible dirty edge strip detected - edge strip on drum should be cleaned

Applies to:

• Green

Service Information:

At least 2 false edges were detected while searching for the plate edge. These false edges are often caused by a dirty edge strip. Clean the strip following instructions in the Service Manual. Check the strip for scratches while cleaning. If the strip is badly scratched it may need to be replaced.

False edges can also be caused by a foreign object near the plate edge, such as a slipsheet stuck to the plate.

If the false edges continue after cleaning the strip, a "daom cal" should be performed and saved. Also the position of the edge strip should be checked by performing a "plot edge cal" command followed by a "drum edge" command. The green edge spot should be centred on the bottom half of the strip.

Operator Action:

The edge detection strip should be cleaned as soon as possible, following the instructions in the Platesetter Operator's Manual.

Cause:

• Dirty or scratched edge strip
• DAOM calibration inaccurate
• Slipsheet stuck to plate
• Edge search spot not centred on bottom half of edge strip.
