Error Message:

HEAD: Possible errors detected in image control data, check image for artifacts.

Applies to:

• Trendsetter_400/800_Proofing

Service Information:

When imaging proofing media with special_plot_mode enabled, an array of imaging control data, called the ILUT, is loaded into the DPE memory. This array is checked for errors both before and after a plot, and if any are found then this message is displayed.

If errors are detected before the image starts then this message will appear to the operator as an error message fatal to the image.

If errors are detected in the array after the image, then the message is displayed to the operator as a warning message only. If this is the case, the image may have artifacts in the form of missing or extra pixels repeating every 5 mm across the image and every 5-20 mm down the image.

Report the error immediately to the Creo firmware group, as it most likely is due to an intermittent firmware error.

When the error occurs, extra diagnostic information will be displayed at the recorder diagnostic interface, which is most critical to help engineering solve the problem. Try and capture all the diagnostic information regarding the plot on which the error occurred.

Operator Action:

If this message occurs as an error message before an image started, then cancel the image and try it again.

If the error occurs as a warning message after an image has completed, check the image for artifacts.

In either case, immediately report the error to Creo Customer Support as the machine may need servicing.

Cause:

• Most likely due to an intermmittent firmware error. Contact someone in the Creo firmware group ASAP with details and a diagnostic capture of the failed image.
• Very small, but non-zero, chance that it is a FDPE hardware error. Try swapping in a new FDPE if the problem persists and Creo engineering can't help in time. If this makes the error go away, tag the FDPE to be sent to Greg Peregrym at Creo for analysis, and specify "ILUT corruption error" on the tag.
