    First time posting, so feel free to redirect me if this has been asked and answered, but I'm trying to trouble shoot blanket problems on a 3600.

    Had one blanket "explode" on press and damage the PIP. Replaced the blanket and the PIP. Press ate another blanket. Replaced the blanket again. Ate it again.

    There's a slight chance I'm at fault, but I've changed blankets before and haven't had problems. This is my first year with the Indigo.

    Sorry I'm late getting back, but thanks for replies. We had to get tech support and learned that

    1). When the press ate the first blanket, it ate it so badly that the impression and ITM cylinders got out of timing badly. Jumped multiple teeth.

    2). This caused multiple problems with paper transport, and with the next four blankets we installed.

    3). We never did learn exactly why the first blanket failed so catastrophically. Apparently it can just happen.

    4). I did infact install one blanket wrong, without impression engaged. Good catch! But the remaining blanket failures did not appear to be related. The timing appeared to have also affected the alignment of the drums so that even with impression engaged they weren't sticking correctly.

    Hope this helps anyone else in a similar situation.

    Thanks for the quick replies.

    Good to know. We still have tech support package, so we're lucky to have someone came out to do it for us. But if we end up buying outright I'll be back with questions.
