Our answer to the question: I recently encountered a problem with a Chemcut developer's (series 2000) rollers. The rollers were coated with TPE rubber. The rollers swelled up allowing the aluminum core to spin freely, obviously not allowing boards to pass through the machine. It is unclear as to what caused this problem. Several factors have been changed within the last 3 months. A new developer solution has been in use on a feed and bleed system. Two new anti-foam chemistries were tried. A new film was evaluated for about 2-3 weeks. Of these changes, does anyone have experience with a similar problem, and could you identify any potential incompatibility issues. I would rather not list the specific vendors, but would like to know if a specific chemical reaction might cause this. Thanks in advance. We experianced this and also roller marks from the swoller pinch rollers rubbing on the converor wheels. This also caused the wheels to skip. We purchased EDPM rollers and have not seen the problem since.
