TECHNICAL TIP: HOW TO CIRCUMVENT SAMSUNG’S ML-2160/2165 CARTRIDGE REPLACEMENT LIMITATION

UniNet offers solutions for optimal performance powered by our Award Winning Technical Team.

On this opportunity we will touch on the Samsung ML-2160, 2165, SCX-3405 printers with cartridge part number MLT-D101S.

Samsung has built in a very devious cartridge replacement limitation on this printer series in which there is a maximum

limitation of 250 cartridges per machine allowed.

There are two issues to consider with this system, one is that a testing bed can be rendered useless after testing 250 cartridges;

the second is that an end users machine can be rendered useless (or dramatically reduced) if the final chip is used

during testing.

- This means only 250 new cartridges (the OEM are included on the count) in total can be installed into the printer.

- Whenever you insert a new cartridge (to be recognized by chip serial number) to the printer, the printer will count "+1" for

the replacement. At the same time, the total accumulated number will be recorded to both the printer and chip of the cartridge.

Now comes the sneaky part: If you take this recorded cartridge to another printer, the install count record in the chip will be writ-

ten to the printer and of course "+1" will be counted, and so on...

In other words, if you take a cartridge from a machine that has run 240 cartridges and install it in a brand new machine, that new

machine will have a total life left of nine cartridges (240+1)!

Once the replacement limitation of 250 has been reached, the printer will stop its functionality.

As a result, our technical team strongly recommends: “Do not test the toner cartridges with a new chip before delivery." Use an

in-house testing chip (marked with bright paint) to run all the cartridge testing and then after it has passed, install a new chip on

the cartridge.

Otherwise, customer printers would be counted up to the number on the cartridge (from your testing printer), and once changed,

it is unrecoverable.

Consumable Yield

As stated by Samsung, the MLT-D101S cartridge, shipped with the machine (starter), will print 700 pages while the replacement

cartridge will print 1,500 pages as per ISO/IEC 19752 specs.

The starter cartridge shipped with the machine can only be identified by its serial number and the word “Initial” printed in its label.

The aspects of the cartridge are rapidly recognized as a Samsung product, however as with prior releases, the presence of

plastic rivets instead of classic screws to secure end plates, does create the need to carefully drill all seven positions and replace

the rivets with standard self-tapping cartridge screws for proper removing, remanufacturing and assembling.

In the following figures, we can see the relevant details in both end covers.

The real surprise is inside the cartridge as soon as it is removed and separated into its two sections. First, we find that the

developer roller is no longer made of controllably conductive urethane as with prior models but replaced by a aluminum sleeve

set at a particular non-contact distance marked by the presence of bushings at each end of the roller. This metal roller is treated

at a given rugosity and does not have any resistant coating as we find in a cartridge working with magnetic toner, except that in

this case the toner is non-magnetic and there is no magnet inside the roller.

The separation between the roller and the surface of the OPC is about 0.14mm, meaning in effect there is a jump of the toner

from the roller surface to the OPC surface in the moment of development of the latent image in the photoreceptor. The surprise

does not end there and we see that the doctor blade working at a tangential position is made of stainless steel instead

of polyurethane. This metal to metal contact with toner as intermediate can only mean severe degrading or wear of the surface

with use, particularly if a non-specific toner is used, such as the “Universal” being offered by suppliers.

Our lab tests have shown that the actual MLT-D101S toner is of a new design and might not be exactly as in previous models.

The use of a non-specific toner could accelerate the wear of the developer roller surface treatment and a rapid decay of the print

quality offered by the cartridge.

REQUIRED TOOLS

1. Toner approved vacuum

2. Small common screwdriver

3. Phillips head screwdriver #3

4. Needle nose pliers

5. Chisel blade X-Acto style knife

6. Small drill bit 5/64” (to match self-tapping screws) and small electric drill

REQUIRED SUPPLIES

1. New replacement toner for use in Samsung ML-2165W / MLT-D101S

2. New replacement chip for use in ML-2165W to match region

3. New OPC drum (optional)

4. New developer roller (optional)

5. New PCR (optional)

6. New doctor blade (optional)

7. Self-tapping cartridge screws 1/8” x 1/4” (7 pieces)

8. Conductive grease

9. 99% isopropyl alcohol

10. Wiper blade lubricating powder

1. Place the cartridge in position, and with the chisel blade section, the head of each plastic rivet holding the left end cover.

2. Mark the center of each cut and drill a hole with the small

drill bit no deeper that 3/16”.

3. Tap the four screws into position.

4. Repeat the work sectioning the heads of the rivets on the opposite end cover (marking the center of the rivets, drilling and tap-

ping the three screws).

5. Proceed now to remove the screws of the end cover on the right (contact side) and pry open with the small screwdriver at

different consecutive points until separation is accomplished. Even though the cover seems to be formed by two sections, it is a

unit with a rather thin centerpiece. Worth noting also the way the chip is internally held and the need to be replaced prior to

reinstalling the cover.

6. Repeat the removal of the left end covers in its two parts, starting with the top one and then the lower one.

This will allow separation of the cartridge in two sections.

Begin working in the image section.

7. Slide the OPC drum axle out just enough to allow the opposite end of the drum to be lifted out of position and remove it.

Leave the drum axle inside the OPC.

8. Remove the PCR, applying slight leverage to both holders with the small screwdriver.

10. Vacuum the waste bin and surrounding areas. Inspect also

the state of the wiper and the recovery blade seals.

9. Remove both Phillips screws and remove the wiper blade by prying it out.

11. Lubricate the wiper blade with lubricating powder and install with the two Phillips screws.

12. Wipe the PCR surface with a soft cloth to remove all traces of toner, and if need be, use a PCR cleaning liquid. Most marks

and even fingerprints can be removed with a damp cloth containing a few drops of neutral detergent and fractioning the surface

with axial strokes. Then, use a damp cloth to remove the rest of detergent and dry completely before installing the PCR. Clean the

PCR saddles with isopropyl alcohol and apply a slight coating of conductive grease to both ends. Continue to install the PCR

observing the proper location of each saddle. The green end to the right saddle and the white end to the left saddle.
