Anyone have any tricks or suggestions?  We can't seem to get the old rubber off.  :(

This worked well for us a few times...

Use a manual press flash. Leave the flash above the platen, wait awhile, and the adhesive should get hot enough to peel off the rubber.  We then used some solvent to get the access adhesive off of the aluminum.

You could use a stiff paint remover blade the one with a handle, it has a sharp edge and you can start on one corner and just work your way underneath the rubber.

This method works very well rubber gets big bubbles and browns like a marshmallow  , my printers like to practice this method every once and a while :)

Yup.  When I had my first auto, we had to use a manual press flash in one of the heads.  Needless to say after lunch one day I was ordering up some new rubber from action engineering.  I then knew how to remove the other 7... ha!

Yep, heat to soften the adhesive. Great on old self stick floor tiles too...

Thanks everyone.  It took two hours, but I got it off finally.  Phew...what a pain.

Xylene.  Totally gross but melts that 3M adhesive.  Ventilate!
