Replacing the Toner Cartridge (OKI P/N 52111701)

The number of pages you can print with one toner cartridge varies depending on the type of docu- ments you usually receive or copy. A toner car- tridge will print about 1,875 pages/Letter size of standard business communications at a typical print coverage of 4% (equivalent of ITU-T No. 1 test chart). The first toner cartridge installed in a new image drum unit will have a decreased yield be- cause the image drum unit itself has to be filled.

If your machine displays REPLACE TONER CART., replace the toner cartridge with a new one. However, if the print density is high enough, you can continue to use the toner cartridge without replacing it until the print density becomes too low. If the print density becomes low even before your machine displays REPLACE TONER CART., gently wipe the lens surface of the LED array (see Step 7).

If the print density does not improve, replace the toner cartridge. When your machine’s display shows CHANGE DRUM, replace the image drum unit.

Warning: Be careful when handling the toner cartridge. Do not let toner spill on your clothing or other porous materi- als. See the Safety section of this manual.

CAUTION: If you open the top cover, you will see a

label that reads: (CAUTION-HOT). This portion is extremely hot and must not be touched under any circumstances.

1Lift the top cover into an upright position.

2Grasp the control panel. Pull upward and toward you until it releases. Swing the control panel up and out of the way.

3Pull the gray lever on the old toner cartridge all the way toward you. Carefully pull the old toner cartridge out of the image drum unit. Dispose of it in the plastic bag you received with your new toner cartridge.
