Error Message:

ALE: timeout waiting for Roller 4-Up suction to build up, threshold = <n>, current level = <n> (index word)

timeout waiting for Roller 4-Up suction to release, threshold = <n>, current level = <n> (index word)

Applies to:

• Trendsetter_400/800_Proofing

Operator Action:

This error is likely due to the media not being loaded properly. Select RESUME from the workstaion dialog box. If this does not correct the problem, select CANCEL IMAGE from the workstation dialog box. You may need to open the proofer and remove the media if it isn't ejected on it's own. If CANCEL IMAGE is not available, select MEDIA CLEAR and make sure that you remove all media other than the carrier in the machine. If this problem recurs frequently contact Creo service.

Service Information:

When the problem happens, determine if the media is grabbed correctly by the indicated roller. If it is not, then watch a few load/unload cycles with the doors open and try to determine what is going wrong. If the media is being loaded correctly, then the roller suction sensors are not working properly, the suction thresholds are mis-adjusted, or the roller suction is not being generated properly. You can check the suction sensor readings using the "proof" command. Additionally, at the end of the error message, an index word is printed to help determine which threshold in NVS is being used when error occurs.

• (load_3a) : 0
• (load_3b) : rvgt
• (load_3c) : rvgt
• (load_5) : rvgt
• (load_6) : rvot
• (unload_3a) : rvot
• (unload_3b) : rvgt
• (unload_4a) : rvot
• (unload_4b) : rvgt
• (unload_4c) : rvgt
• (unload_4d) : rvgt
• (unload_4e) : rvot
• (unload_4g) : rvot

Please make sure that the error is NOT due to mechanical alignment before adjusting NVS thresholds.

Service Information:

The suction sensors can be over-ridden using the "alproof vsi" parameter. This will allow the machine to operate, but in a much slower and more dangerous manner. In this state, the machine should only be used if absolutely necessary and if it will be fixed very soon. When the sensors are disabled, the machine is running "blind", so it could incur additional damage if used. Use extreme caution.

Cause:

• The machine checks suction levels on the roller almost every time it is turned on, to ensure that the suction level builds up to the appropriate threshold. When this error occurs, the indicated suction level did not build up in time. This is most likely due to the media being loaded or grabbed incorrectly. It is also possible that the indicated suction sensor is not working properly, the thresholds are not set properly, or vacuum is not being generated properly.
