ALWAYS refill in an area where you can tolerate a spill. Use a area such as a workbench when refilling.
1. Turn the cartridge upside down, so that you are facing the BOTTOM of the cartridge.
2. Locate the plastic handle plastic TAB on the side of the cartridge. They are sometimes blue
in color. The tab is about 1cm x 1cm in size. Depress the TAB. This will unlock the handle.
3. Now you can turn the HANDLE until it exposes a slit opening. Inside this opening is the
chamber that holds the toner.
4. Connect the toner pouring nozzle to the toner bottle, and using the funnel provided you can
now start pouring toner into the toner cartridge. After you have poured all the toner, you
need to close the cartridge by turning the handle in the opposite direction to when you
opened it. You need to make sure that you COMPLETELY close the slit-hole opening
so that no toner can fall out. You need a tight seal to prevent spillage.
The OKIDATA C5100 cartridges have sensors to detect how much toner is left in the cartridge. Some -
times, this sensor will prevent the refilled cartridge from printing. You can quickly and easily “reset”
your cartridge so that the printer recognizes it as a brand new cartridge and allows you to print. First,
it is important to note which cartridge you have - is it a “starter cartridge” (the type that come with a
new OKI C5100 printer), or is it a “replacement cartridge” (did you buy the cartridge separate to the
printer). To identify which cartridge you have, see the picture below
2.If you have the starter cartridge you will need to cut a 1.5” X 11” strip of paper. You will use this piece of
paper to fool the printer and avoid the “cartridge is empty” message. You have 1 sensor for each color, place
this piece of paper between the sensors and the printer as shown in picture above. When you insert the strip of
paper the printer will think that you are using the replacement cartridge from the store (not the starter
cartridge).

1. Look at your cartridge on the side with the blue handle. Determine wich cartridge you have by the tab on
the blue handle. If you have a WHITE tab (show on left) then you just need to wipe this sensor down with a
clean paper towel. This sensor needs to be ABSOLUTELY CLEAN in order for the printer to recognize the
cartridge. You do not need to use the paper reset method. If you have a SILVER tab (shown on right) then you
will need to use the reset method shown below.
