This sealing channel end foam is Static Control's solution for properly sealing and preventing leakage from the mag roller section of the toner hopper.

Foams should be replaced when they are damaged or worn. Even if only one foam needs replacing both foams should be replaced at the same time.

Made with a polyester film strip on the top side that prevents the seal pull film from sticking to the foam as it's pulled.

One of each type of foam (open and closed) is necessary for each cartridge.
