Sensors?? "t jam"

Anyone know what the "t jam" is for? i was having bother with it when was running sheets and didn know what it was so couldn fix it

 

Could you be more specific.

 

As i was starting the press printing first few sheets would come through then the machine would stop dead and on the ok screen would be the "T Jam" sensor signal

 

Are we talking about QMDI press.

 

34 di ?

 

Sorry can't help you this is a presstek, I have no experience with it.

 

ah right ok thanks anyway

 

That is your Sheet travel jam detector.

 

If it is shutting down after a few sheets and there is no jam up, then it is a dirty sensor. Look in your manual to find it and go over it with a dry rag. On rare occasion I have had paper cut to just the wrong lenght as to fool the sensor, in which case I just turn it off on the console. Of course turning it off opens you up to the possibility of bigger problems, so do that at your own risk.
