Stuck Print Core

[Choclit99 0]

I have an S5.  The left print core got trashed by a nylon print that detached from the glass and eventually yielded a melted nylon blob surrounding the bottom of the print core.  It got most of the blob off but the print core is no "toast" (technical term...).  The wires are damaged so the system doesn't think there is a print core there at all.

 

When you normally change a print core, the system releases some type of locking mechanism.  I can't do that so I need to know how to manually unlock the bad print core so I can replace it.

 

Anyone know how to do this?

 

Thanks,

Ed
