Cartridge/Machine Reset Guide Version 4
By Mike Josiah, Summit Laser Products
In the early days of this industry, life was fairly simple. There were only 3 or 4 cartridges to remanufacture, and
nothing to reset. Then Sharp released the JX-9500 Engine which needed a fuse to reset the counter in the printer.
Okidata followed suit with the OL-400 where you have to follow a procedure through the menu of the printer.
These days, almost every engine released has it’s own unique reset procedure. Even Canon has gotten into the act
with their color lasers (HP-4500, 8500). The drum units have a microprocessor (IC) that has to be reset or
replaced in order for the cartridge to continue to work.
How to reset a particular cartridge or machine has become the most commonly asked question our technical
support department gets. (Especially from delivery people at the customer’s site!). With the amount of different
engines being used these days, it's almost impossible to keep all of these procedures committed to memory. In
light of this, we have compiled the reset procedures for the more popular machines/cartridges being used today.
They are listed in alphabetical order.
Some of the cartridges/machines listed currently cannot be recycled, (usually due to a lack of replacement parts).
We are listing those now against the day that replacement parts become available.
Since cartridges that need some type of reset seem to be the wave of the future, this will be a work in progress.
As such we will be posting updates to this guide on our web site as they become available. If you have a reset
procedure that you have confirmed works and is not listed here, please let us know and we will include it in our
next update. This is definitely an area where a little knowledge shared can benefit the entire industry!
We highly recommend that a copy of this guide be kept in your delivery van.
We would also like to add a special thanks to Brett at The Parts Drop for his help on the Xerox machines.
Brother HL-630 OPC
Brother Cartridge Part #DR-100
OEM Stated Yield: 11-15,000
This cartridge does not use any type of reset procedure. These cartridges according to the Brother manual should
be replaced whenever the copy quality deteriorates. Since this could occur almost at any time, there is no need to
have a counter. We only included it here because all of the other Brother engines DO have some sort of reset
procedure.
Brother HL-720 OPC
Brother Cartridge Part #DR-200
OEM Stated Yield: 20,000
New drum cartridges come with a clear “Starter Sheet” installed inside the cartridge. When the cartridge is
installed and the cover closed, the printer will eject the sheet and at the same time, reset the drum counter. This
sheet is also present in the DR-300 cartridges.

Brother Cartridge Part #DR-300
OEM Stated Yield: 20,000
New drum cartridges come with a clear “Starter Sheet” installed inside the cartridge. When the cartridge is
installed and the cover closed, the printer will eject the sheet and at the same time, reset the drum counter. This
sheet is also present in the DR-200 cartridges.
Brother HL-1240 OPC
Brother Cartridge Part #DR-400
OEM Stated Yield: 20,000
After replacing the drum unit, keep the front cover open and press “Clear”. The display will show “Replace
Drum? 1.Yes 2.No” Press “1” the display will show “Accepted”, close the front cover. The counter is reset!
Canon NP-1010/1020/C-100 OPC
Canon Cartridge Part # F43-2101-700
OEM Stated Yield: 15-20,000
The copier will show “Replace Drum” when the waste chamber fills up with toner. The cartridge must be taken
apart, cleaned thoroughly, drum and wiper blade replaced (uses A-30 parts). Make sure that the waste chamber is
cleaned thoroughly as the machine will not reset if there is toner left inside.
Canon NP-6012/C-120/6412 OPC
Canon Cartridge Part # F43-5411-700 (NPG-11)
OEM Stated Yield: 30,000
To reset the counter in the NP-6012/6412/C-120 OPC cartridges the connector on the rear of the cartridge must
be replaced. New replacement chips are available with the housing. Unscrew the old connector and replace with
the new. These drums are rated for 30,000 pages.
Canon NP-6016/C-160 OPC
Canon Cartridge Part # F43-4921-700 (NPG-9)
OEM Stated Yield: 40,000
The drum unit for these cartridges is rated for 40,000 pages. The machine will show “Replace Drum” at 40,000
pages or when the waste toner section is full. These cartridges have a reset chip built into the connector. This
connector must be reset before a rebuilt cartridge will work. Currently no new replacements are available, but
there are some companies that will reset the OEM chip for you.
Canon NP-6521/C-200 OPC
Canon Cartridge Part # F43-4921-700 (NPG-9)
OEM Stated Yield: 50,000
These machine use the same cartridge as the NP-6016, but the yield is 50,000 not 40,000. Since the same chip is
used, the decision must be made by the machine not the cartridge.
The drum unit for these cartridges is rated for 50,000 pages. The machine will show “Replace Drum” at 50,000
pages or when the waste toner section is full. These cartridges have a reset chip built into the connector. This
connector must be reset before a rebuilt cartridge will work. Currently no new replacements are available, but
there are some companies that will reset the OEM chip for you.

Canon PC-850
Canon Cartridge Part # F100 (F41-9921)
OEM Stated Yield: 10,000
If the "Replace Cartridge" light is still lit in the display after replacing the cartridge, the customer can follow the
below steps to reset the copier. This procedure should be done every time the cartridge is replaced:
Hold down the "A" (Automatic Exposure) key for approximately four (4) seconds or longer.
After approximately four (4) seconds have elapsed, "UC" appears in the Copy quantity/Copy ratio display. Press
the "Start" key. "UC" will flash for about 20 seconds in the Copy quantity/Copy ratio display. The copier will
automatically perform a toner distribution operation, and then you will return to the normal copying mode.
NOTE: - Be sure to press the "A" key after replacing each cartridge. If you do not, your first few copies will
not be clear copy images or the Replace Cartridge indicator may light. If either of these two problems occurs,
press the main unit power switch to OFF and then to ON again. Afterwards, perform the above steps.
If copies are too dark or too light after you have replaced the cartridge, open the front door and adjust the copy
exposure using the exposure re-calibration slide control switch.
DEX 625 (Samsung SF-5500)
Dex Cartridge part # 6950
OEM Stated Yield: 12,000
This cartridge is actually two separate cartridges, a toner and a drum cartridge. They are sold as one unit under
part # 6950. NOTE: It is very easy to ruin the sensor on these cartridges when cleaning. They are very static
sensitive. We highly recommend that the sensor be removed before cleaning and replaced before the cartridge is
filled.(There is a hole in the chamber that will leak if not replaced.
There are two reset procedures that must be followed in order to have this cartridge operate properly. On the
drum unit there is a glass fuse that must be replaced. The fuse is a 125V,100mA, 5x20mm fast acting glass type.
Once the cartridge(s) have been installed, you must perform the toner initalization. Press FUNCTION, 7, YES,
NO, YES, YES. The machine is reset!
Fuji-Xerox XP-11 Toner & OPC (Xerox 4030)
Xerox Part #’s 6R281/13R32
OEM Stated Yield: 20,000
With the printer off, press and hold the reset button located next to the power cord. While still holding the reset
button in, turn the power on. The reset procedure is the same for both the toner and drum cartridges.
HP Color LaserJet 4500 OPC (Canon LBP-83X)
HP OPC Part # C4195A
OEM Stated Yield: 25,000
These cartridges have what has become known as a killer chip installed on the left side of the cartridge. The chip
is actually just an IC plugged into a socket on the back of the electrical connector, which can easily be changed. It
would seem that HP or Canon has plans to recycle these cartridges. Even though they look the same, the
programming on these chips is different from the HP-8500.
New reset chips are now available to reset these cartridges. These cartridges also have windows that work with an
optical sensor inside the printer that determines if the waste chamber is full or not. It is more than likely that if the
waste chamber fills up, the machine will shut down. We are not sure if the cartridge waste chamber is cleaned
out, it will continue to run until the chip finishes its page count. The Canon version of this printer is the CLBP460PS

Kyocera OPC Part # DK-3
OEM Stated Yield: 10,000
There is a small black fuse located on the board inside the cartridge. This fuse must be replaced each cycle by unsoldering the old and soldering in the new. This fuse is a special 250mA one that should be purchased from your
supplier. The same fuse is used in the F-3010 OPC Cartridge.

Lexmark Optra Se
Lexmark Cartridge Part # 12A0825 (Prebate), 12A0725 (Non Prebate)
OEM Stated Yield: 23,000 (Both) (Lexmark does not currently produce a low yield cartridge.)
The “Prebate” cartridges have what has become known as a killer chip installed on the top left side of the
cartridge. The packaging for the chip looks more like a battery than a chip, but it is definitely a chip. This
package allows a special reader inside the machine to read the chip with out any wires connecting it. Some
companies are now starting to offer a reset service, but there may be some restrictions. Check with your supplier
for more information. On the Non-Prebate cartridges however, the chip is also present, but the killer part is not
active. These cartridges can be re-manufactured as much as you want , the chip will not interfere.
Lexmark 4069 (Optra T)
Lexmark Cartridge Part # 12A5840/12A5845 (Prebate), 12A5740/12A5745 (Non Prebate)
OEM Stated Yield: 5840/5740: 10,000. 5845/5745: 25,000

Lexmark 4045 (Optra M)
Lexmark Cartridge Part # 17G0152/17G0154 (4K00198/4K00199 Discontinued)
OEM Stated Yield: 0152: 5,000, 0154: 15,000
Included here only because of the physical similarity to the other Optra S, Se. & T. These cartridges do not have
any chips, or anything else that has to be reset. They even eliminated the Yield Wheel! At this time there are only
“standard “ cartridges, Prebate cartridges have not been released, and there does not seem to be any plans for
Lexmark to do so.
Minolta Color PageWorks
Minolta Part # 1710437-001 (Black), 1710437-004 (Cyan), 1710437-003 (Magenta), 1710437-002 (Yellow)
**Old Minolta Part Numbers 0940-501/701/401/601 Discontinued**
OEM Stated Yield: 20,000 (Minolta and Lexmark)
Lexmark Optra SC 1275 Toner
Lexmark Part # 1361751 (Black), 1361752 (Cyan), 1361753 (Magenta), 1361754 (Yellow)
The Minolta Color PageWorks Toner cartridges all have a glass fuse located under the two metal contacts on the
bottom of the cartridge. The replacement fuse is a fast acting, 5 x 20mm, 250V, 80mA, glass type. These fuses
should be replaced every cycle. The Minolta and Lexmark cartridges are NOT interchangeable. The small fins on
the bottom of each are in different locations. These fins will block the installation of the wrong cartridge into the
machine. The same fuses are used for both cartridge types.
Mita LDC-650
Mita Cartridge Part # 63582010, Pitney Bowes Part # 9640
OEM Stated Yield: 10,000
On the gear side of the cartridge there is a large white gear with a floating tab mechanism that has two notches in
it. For the machine to accept the cartridge as new, the tab must be set so that the outermost notch is engaged. Be
careful to reset this tab after testing as it will automatically move to the inner notch every time the cartridge is
installed. If the tab is left in this position, the machine will show change cartridge when the cartridge is installed.
NEC LC-800 OPC
NEC OPC Cartridge Part # 20-020
OEM Stated Yield: 7,000
With the power on, open the cover.
Press and hold the PC RESET button down. While continuing to press the button, insert the OPC cartridge.
Release the button and close the door. Press the ONLINE button. The counter is reset!
OKIDATA DRUM CARTRIDGES
Okidata over the years has released a lot of printers/fax machines all with different engines. Unfortunately almost
all of them require a different reset procedure. In fact even some of the machines that use the same engine have
different reset procedures! The following procedures are grouped by the Engine, (underlined), and then by the
machine model number/s. The machine model numbers are also in a slightly smaller point size. The first engine is
the Okidata OL-400/800, but the first actual reset procedure is for the OL-800 series only, followed by other
machines that use the same engine but have different reset procedures. Just to make things a little more crazy,
there are also machines that use different engines, but use the same reset procedure. These are grouped as above,
but with a note that says what other machines also use that procedure.
Hopefully this will help clear up some of the confusion on what procedures to use.
