We have a Avantra 44s and at start up it sometimes gives us a error code of 168 and sometimes it doesn't. Either way when we go to send film we get error 1 carriage jam. Sometimes we can turn the machine off and back on and all will be fine and other times we will have to unload film and move the carriage by hand some and restart, reload and it will be fine. The rest of the day it will be fine it's just at start up we have these issue's. Any ideas.
