HP designjet 450c problem

Hi all,

I've just started having this problem. Nothing has been done to the printer
to cause this. Sometimes the print heads will catch the right side of the
paper rip it and get gaught up in the mess. It just started happening this
week. I thought it might have been the paper. I got another roll of paper.
It's still catching. It doesn't happen every print. Only when I'm not here
and someone is in desperate need of using it. Has anyone else experienced
this before?


TIA,
Dan
