I have a Studer A807 and I need to replace the pinch roller because the old one just "melted" and thick sticky rubber ran down the front of the machine whilst it was in storage.
Can anyone explain this?
I haven't put chemicals on it and its just a mystery to me.
Certainly heat can cause the rollers to deteriorate, however, this can also be caused by using improper chemicals to clean pinch rollers if you did not purchase the unit new. If you purchased it used, the previous owner may have caused this problem.
