1) Place the cartridge with the handle facing away from you. Slice off the 3 plastic rivets with a Square Xacto type blade on the contact (chip side) end cap.

12) Clean the PCR with your normal PCR cleaner and install in the cartridge. Make sure the guides fit in place and the rollers fit into the holders properly.
WARNING: Do not clean the OEM PCR with alcohol, as this will remove the conductive coating from the roller. If the PCR is an aftermarket, follow the cleaning methods recommended by the manufacturer. If the PCR is an OEM, we recommend it be cleaned with your standard PCR cleaner.
