Replacing the Toner Cartridge (OKI P/N 52111701)
The number of pages you can print with one toner cartridge varies de-
pending on the type of documents you usually receive or copy. A toner
cartridge will print about 1,875 pages/A4 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 because the image drum unit itself has to
be filled.
If your MFP 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 MFP machine displays REPLACE TONER CART.,
gently wipe the lens surface of the LED array (see Step 6).
If the print density does not improve, replace the toner cartridge. When
your MFP 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 materials.
See the Safety section at the beginning 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.
1 Lift the MFP machine’s top cover into an upright position.
