Originally these printers were equipped with a separation pad that was all one unit. The pad was part of the holder. Within a year or two the separation pad was updated and the new separation pad assemblies came with the holder and a pad that is easily removed without removal of the whole assembly. If you see the old one-piece pad still installed, are you noticing multiple feeding? Typically, then, you can only feed one sheet at a time because otherwise it grabs five or six sheets at a time. Replacement will be necessary (part# RG5-5281). Replacement is easy.

The 4100 series comes with the updated part so if multiple feeding is occurring, only the pad will have to be replaced (part# RF5-3086). It's a good idea to have an updated separation pad assembly in stock.
