Error Message:

ALE: No media detected on unload ramp, check inside machine

Applies to:

• Trendsetter_400/800_Proofing

Operator Action:

An unload of the media has failed. Select RESUME from the workstation dialog box. If this does not work, select CANCEL IMAGE from the workstation dialog box. You may need to open the proofer and remove the media if it isn't ejected from the proofer on it's own. If this problem recurs frequently contact Creo service.

Service Information:

Determine if the media is being dropped during the unload or if the sensor is not working. Under normal operation, the media should stop just before the sensor, and jog out over the sensor until the media is detected, and then eject the media at high speed. If the media is present over the sensor then the sensor is probably not working. Check the sensor alignment and cabling, and the TEE board. This sensor is analog and detects the presence of the media during an unload by measuring reflectivity. You can read the sensor using the proof command and should see it jump by at least 300 when media is present on the unload ramp over the sensor.

Service Information:

The sensors can be over-ridden using the "alproof si" 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:

• Media is not being detected on the unload ramp. Either the media is not there (because it has been dropped before this step in the unload procedure) or the unlaod sensor is not working.
