The Lexmark Opera T, Opera S and Opera SE 3455 laser printer cartridges are all very similar, yet not interchangeable with a few distinct differences that will be pointed out to you later.

Since the remanufacturing process is basically the same for all, the following guidelines will be based on the Opera T, yet address all three cartridge types.

Below are the 53 steps to know how to remanufacture your Lexmark Optra:

T/S/SE 3455:

•1382920
•1382620
•1382625
•1382925

Step #1:

•Place the cartridge on the work table with the drum facing upward and the small drum gear towards you. Using a small bladed screwdriver, pry off the developer roller drive gear and set it aside.

Step #2:

•Rotate the cartridge to the right so the toner hopper is facing you. Using a spring hook or needle nose pliers, gently remove the toner hopper tension springs from the posts at each side.

Step #3:

•Grasp the toner hopper with the left hand and the waste hopper side plate with the right. Gently bend the side plate outward, while sliding the toner hopper to the left to expose the right guide post.

Step #4:

•The drum cover may be taped back to facilitate handling. Using a small flat bladed screwdriver or needle-nose pliers, take off the retaining clip on the left side of the drum shaft.

Step #5:

•Now you will need to hold the large gear end of the drum with your left hand, pull the drum shaft out with your right. Remove the drum and set it aside, just be sure not to lose the washer on the small gear end. If lost, it may take some time finding a new one, so be careful, time is valuable.

Step #6:

•Next, remove the two screws holding the wiper blade using a #1 Phillips Screwdriver.

Step #7:

•Carefully, slice the sealing tape on the topside of the waste hopper covering the top of the wiper blade (instead, some cartridge uses a foam seal behind the wiper blade, if so, delete this step if necessary). The PCR access door opens inward and sets on the horizontal lip of the wiper blade. Open the PCR door to remove the wiper blade and be careful not to break the two small plastic alignment pins positioning the wiper blade.

Step #8:

•Empty out the toner from the waste hopper and inspect the recovery blade for nicks, tears, or wrinkles and replace as necessary.

Step #9:

•While holding the waste hopper cavity firmly with your right hand and the wiper blade in your left. Open the PCR door with your left thumb and install the wiper blade on the waste hopper and secure with the Phillips screws.

Step #10:

•Now, apply a small amount of padding powder to the wiper blade, drum and recovery blade. Install the drum, washer, drum axle and retaining clip and set the waste hopper aside for now.

Note: If the OEM (original equipment manufacturer) drum comes with a one way spring, it may need to be transferred to the new drum.

Step #11:

•Place the toner hopper on your work area (label up) with the developer roller facing you. Using your fingertips of both hands, gently pull off the doctor blade spring and set it aside.

Step #12:

•Using a small flat bladed screwdriver pry against the base of the contact plate and remove the contact and lift the end piece from the developer roller.

Step #13:

•Grasp the left end shaft of the developer roller and lift it out to the left, doing your best not to damage the Teflon washers or Mylar blades.

Step #14:

•Remove the Teflon washers from the developer roller and inspect them thoroughly for damage and wear. Replace the Teflon washers as a set.

Step #15:

•Turn the toner hopper to the right so the fill plug is facing you. Using a small flat bladed screwdriver, pry the slotted encoder wheel off and set it aside.

Step #16:

•Using the same screwdriver, pry out the toner fill plug carefully and doing your best not to damage it. Clean the filter inside the plug with either vacuum or compressed air.

Step #17:

•Empty out all the toner from the toner hopper and clean the hopper with vacuum or compressed air. Be very careful not to damage the foam rollers or Mylar blades.

Step #18:

•Using a cotton swab and isopropyl alcohol, clean the developer roller ends, and seal at each end of the foam roller.

Step #19:

•Clean the underside of the DR bar with a cotton swab and isopropyl alcohol.

Step #20:

•Clean under the ground contacts for the foam roller shaft and the DR bar with a cotton swab and alcohol.

Step #21:

•Clean the developer roller with a dry soft lint free cloth or compressed air only. Clean the developer roller shaft with a cotton swab and alcohol.

Step #22:

•Install the Teflon washers on each end of the developer roller and slide the flat (keyed) end of the roller into position on the right side of the toner hopper. Lower the left end into position being careful not to damage the Teflon washer on that side.

Step #23:

•Install the brass end piece and contact plate into position on the left end developer roller shaft. On the Optra T and SE 3455 rotate the brass end piece downward until the lobe rests between the legs of the contact plate.

Step #24:

•Re-install the DR bar leaf spring with the point of the “V� stamped on the spring pointed towards you.

Step #25:

•Carefully pour the correct amount of toner into the hopper and re-install the fill plug.

Note: The toner amount must be matched to the correct encoder wheel, key tab and chip to ensure that the customer’s machine does not reject the cartridge.

Step #26:

•Re-install the plastic encoder wheel.

Step #27:

•Place the waste hopper top down on your work area with the opening facing you and the hopper tension springs out of the way. Turn the toner hopper label down and insert the left roller guide into the slot. Lower the right side downwards, while pulling outward on the waste hopper side plate.

Step #28:

•Re-insert the guide posts into the proper holes in the waste hopper side plates and reattach the hopper tension springs. Inspect thoroughly for correct toner hopper position and ease of movement.

Step #29:

•Re-install the developer roller drive gear. The cartridge is now ready to test.

Step #30a:

•At last, align the encoder wheel with the three slots in the down position before packaging.

Step #30b:

•Test the cartridge.
