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.
2) Gently pry off the end cap. The end cap looks like it’s in two pieces but it’s not. Be careful not to break it when removing!

4) Gently pry off the end cap. This one is actually in two pieces.

10) Clean out any remaining toner from the waste chamber. Be careful to keep the wiper blade seal clean.
11) Re-install the wiper blade and two screws
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.

It is highly recommended that the Doctor Blade be cleaned. Failure to do so will cause streaking. Dampen a cotton swab with alcohol, and clean the blade. Be careful not to press too hard and damage the blade. If the blade has a heavy buildup of toner on it, clean it with Acetone, and then alcohol.
