I printed 80 pages 300gr. SRA3+ Biotop, this paper we use almost everyday and never had any trouble with it.
When the 80 pages where printed i wanted to print the other side, as you do. So turned them like I always do and enterd them in to the tray.
It printed at first normally untill +-5 pages where done than sudenly tray 5 kept opening and closing.
As soon as it was at the top where the printer normally stops and takes his paper it opend again, without any error.
And it never stops untill i delete the file in the Fiery Command Workstation.
I even restarted the printer and it's still the same.
I deleted the order in the Fiery rebooted it and put a new order in it, still the same.
I even shutted the printer down, put it out of the electric socket and waited about 30 min and put it back in, start it, put a new order in and still the same happens...
Please help me.
Sorry for my bad English and correct me if I misunderstood, but tell me that the machine said the tray cover 5 is open or is a missfeed (in this case the machine show a faut code). Because if it said the cover is open it could be a defective cover switch or a broken wire and if is about missfeed could be used or dirty feed rollers. Also it could be a small lift gear broken.
