CARRIAGE: unexpectedly arrived at AWAY position - image size may have been too large |
Applies to: |

Service Information: |
The carriage AWAY switch was tripped unexpectedly. This can happen if the carriage stalls when moving towards the HOME switch, or if the image data sent from the workstation is incorrectly sized or positioned with respect to the actual plate size. This error is also reported if the "carriage move" command moves the carriage to the AWAY switch. If this error is occurs while imaging, the likely cause is incorrectly sized or positioned image data. Check that the actual plate size matches the plate size entered at the workstation. Also check that the start of the image has not been offset by workstation or NVS parameters. The following NVS parameters should be checked: "set gc sss", check with integrators for correct setting "set gc sssa", check with integrators for correct setting "set mode <N> sssa", which should normally be 0. It is also possible that the carriage stalled while performing asynchronous retraces (when waiting for the RIP). The imaged plate should be inspected for artifacts. Look for dark bands where the carriage stalled, or places where the image is "compressed". Another image can be attempted, preferably one with many asynchronous retraces, and the leadscrew watched. Watch particularily where the carriage starts and stops while it waits for the RIP. If any stalling is detected, check the leadscrew for binding and the leadscrew hanger for alignment. Also check the following NVS parameters for correct settings: "set carriage pgain" "set carriage mgain" "set carriage again" These can be temporarily increased from their factory settings if it helps the problem. However this may lead to over-heating the carriage motor so the real cause of the problem should be found. If there is no problem detected with the leadscrew or NVS parameters, the motor or ALE may be at fault. However, check the carriage drive voltages (all carriage drives currently use 80VDC) before swapping these. If this error occured while the carriage was moving in the "home" direction (like when imaging, etc) or the carriage stopped along way from AWAY, suspect that a false AWAY signal caused the error. This is likely due to either a foreign object tripping the AWAY switch, a faulty HOME/AWAY board, or a faulty or loose HA-BP cable. Check for any slip sheets, loose head wires, cable ties, etc in the vicinity of the HOME/AWAY board. If none are detected, move the carriage back and forth ("carriage away" or "x" and then "carriage home" or "w") to see if the error can be replicated by flexing the cable track. |
Operator Action: |
Click on CANCEL (if it's available) or RESUME, since the Platesetter should recover automatically from this error. Check the plate(s) imaged around the time of this error carefully for artifacts. In any case, record the error message and call Creo Service for help as the machine probably needs servicing. |
