First introduced in March 2009, the Lexmark T650 series is based on the Lexmark T650 1200 dpi engine. Depending on the
model, the print speed is from 45-55 pages per minute. As with all of Lexmark’s new heavy duty machines these machines are
loosely based on the older Optra S machines but these are much faster. Due to the speed and fuser characteristics, the toner is
completely different and unique to this series.
THE MACHINES CURRENTLY AVAILABLE BASED ON THE T650 ENGINE ARE:
Lexmark T650dn
Lexmark T650n
Lexmark T650dtn
Lexmark T652dn
Lexmark T652dtn
Lexmark T652n
Lexmark T654dn
Lexmark T654dtn
Lexmark T654n
As with the T640 machines, these cartridges have killer type chips installed in the Prebate or “Return Program” cartridges that
will not allow the cartridge to be used again until the chipboard is replaced. As with other Lexmark cartridges, the non-prebate or
standard cartridges will work with out replacing the chips. Replacement chips are currently being worked on and at the time of
this writing (July 2009), are not available. They should be available as you read this.
These cartridges have a huge profit potential. They are slightly different than previous versions, but still easy and very worthwhile
to do.
Lexmark has also released cartridges for different areas of the world.
The Americas are one region; Europe, Middle East and Africa are another (EMEA); Latin America, and Asia Pacific region is the
last.
As in the past, most likely the only difference in the cartridges besides the part numbers is the chips.

The T65x series of cartridges are slightly different physically from all the rest in the Optra and T series. Since all of the car-
tridges from the Optra S on are somewhat similar, we are showing all the different cartridge versions here and throughout
the next page.

It should be noted that because of the play between the toner hopper and the OPC drum, a shipping lock should be installed in
every cartridge. This holds true even if you are going to hand deliver the cartridge. This lock keeps the pressure off the develop-
er rollers and helps prevent flat spots form occurring during storage.
Machine/cartridge troubleshooting as well as how to run test prints will be covered at the end of this article.
REQUIRED TOOLS
1. Toner approved vacuum
2. Small screwdriver (common style)
3. Phillips head screwdriver (#1)
4. Needle nose pliers
5. Spring hook
REQUIRED MATERIALS
1. T650 toner
2. Drum padding powder
3. Cotton swabs
4. Isopropyl alcohol
5. Cotton pads
6. Long life OPC drum (optional)
7. Wiper blade
8. Shipping lock
9. Recovery blade (optional)
10. Retaining blades (optional)
1. Vacuum the exterior of the toner cartridge. Be careful of the
drum. Place the cartridge on the bench drum-side up (label
face down) with the toner supply towards you. With a spring
hook, remove the two springs from each end of the cartridge.
2. There are two plastic posts from the hopper that fit into the
cartridge shell. Pull the edge of the shell out to release the
posts, and lift up the hopper so that the posts are free.

3. Slide the hopper to the right, and remove from the cartridge.
Pull it out so that the large white bearing comes free. Place the
hopper aside.
4. Remove two small screws from the drum axle plate.
5. Press the drum axle plate out from the inside of the cartridge.
Hold the small helical gear while pulling it out so that the drum is not damaged in the process. Note the location of the spring.

6. On the opposite side, turn the locking ring until it spins freely. Carefully pry off the locking ring and white drive gear.
Gently lift the drum up and out of the cartridge, if you are going to reuse the drum, place it in a light protected area.

8. Place the cartridge so that the waste bin is face-up. Take a
razor blade and cut the foam seal that runs along the back
edge of the wiper blade to separate it from the cartridge. Make
sure to cut along the plastic/foam and not the blade.
9. Hold the cartridge so that it is upright (standing up with the waste bin on the table). With one hand, hold the laser shutter open,
and with the other hand, remove the wiper blade. Work the blade off carefully so that the alignment pin does not break!

12. Place a piece of clear tape along the edge of the wiper
blade. If the tape does not stick well, the area should be
cleaned with alcohol. It is very important to get a good seal
with the tape, otherwise the cartridge will leak. Trim away any
excess tape. Be careful not to allow any tape into the laser port
opening.

13. On the supply hopper, take a pair of needle nose pliers and gently pry off the encoder wheel. Make sure you pry it off from
the center shaft so that the wheel does not become damaged. Also take great care to work the wheel off. If it is pulled straight
off, the shaft may pull through the clutch gear on the opposite side of the shaft. Place the wheel in a safe place. Remember, this
wheel tells the cartridge what type of cartridge it is: Prebate or Non-Prebate. The chip is what tells the machine what type of yield
the cartridge has. If this wheel becomes damaged, it must be replaced.

14. Remove the fill plug from the hopper.
Dump out all remaining toner.

17. Remove the developer roller cover by releasing the tab on the left side, and sliding out the right from the pins.

18. On the left (fill plug) side of the static roller there is a small
metal bushing. Press down on the metal spring, take a small
screwdriver, and pry the bushing up so that the tab on the
bushing is facing up. This will release the bushing and devel-
oper roller.
19. Remove the developer roller. Note that there are no spac-
ers on these cartridges. NOTE: Always remove the doctor blade
spring before removing the developer roller. Failure to do this
will cause the doctor blade to slide down from its original posi-
tion and possibly ruin the alignment. Vacuum/blow the toner
hopper clean.
20. With a cotton swab dipped in alcohol, clean the developer
roller seals located on either end of the static roller section.
These seals are made of a white plastic. Also clean the electri-
cal contact that touches the developer roller shaft. Carefully
vacuum or blow off the developer roller. Be careful not to touch
the roller with your hands, or to damage the roller in any way.
21. Remove the doctor blade by sliding the blade down out of
the track.

22. Inspect the inner and outer retaining blades. If they are
bent in any way, they must be replaced, as they will leak.
23. Clean and install the doctor blade. Make sure the contact
spring is on top of the blade.

24. Place the longer keyed end of the developer roller into the cartridge and install the roller.

25. Install the bushing onto the developer roller shaft, turning
it so that the tab is facing down. This will lock the roller in
place.
26. Install the doctor blade spring.
27. Fill the hopper with the appropriate amount of toner.
Remember: the amount of toner that can be placed in the
cartridge is controlled by the chip. Install the fill plug.
28. Install the developer roller cover. Make sure the pins are
aligned correctly in the cover.

29. Install the encoder wheel. 30. Take the OPC drum and lightly coat with your preferred
Lexmark drum lubricant. Place the OPC drum into the cartridge
with the long thin axle on the contact or non-chip side of the
cartridge. Make sure that the spring is in the proper position.
31. Install the drum axle plate and two screws as shown. 32. On the opposite side of the cartridge, install the black
plastic bushing. Turn it until it locks. Press on the white gear
inside the bushing.

33. Take the toner hopper and install it left side first.
Make sure that the left side post and the white bearing are in their proper slot.
34. On the right side of the cartridge, pull the cartridge shell
out so that the right side post falls into its slot.
35. With the spring hook, replace both springs on to the toner
supply chamber.

36. Re-install the developer roller drive gear. Hold the gear
train and turn the gear until it locks. It’s a little hard to get on
now than if installed before, but it’s easier to install the hopper
this way. Either way is fine though.
37. Replace the chip by removing the screw and sliding the
chip out. When replacing the chip keep the contact side facing
the cartridge.
38. A shipping lock must now be installed. This lock should be
used even if you are going to hand deliver the cartridge. It will
prevent the toner hopper from coming in contact with the OPC
drum, and causing damage to either the drum or the develop-
er roller. Press the two red tabs into the sides of the cartridge
as indicated in the picture supplied with the lock.
