Estimated Replacement Cycle For Toner Cartridges - Oki B412dn User Manual

Estimated Replacement Cycle for Toner Cartridges

When toner level is low, the [TONER LOW] message is displayed on the operator panel--prepare a replacement toner cartridge.
If you continue using the toner cartridge after the above message has been displayed, printing stops with a message [REPLACE TONER/
413:TONER EMPTY]; replace the toner cartridge when that occurs.
Depending on your environment, prints may become light before the above messages are displayed. In such a case, remove the toner
cartridge, and then check the toner inside the image drum cartridge; if the toner is empty, replace the toner cartridge with a new one.
The estimated replacement cycles for toner cartridges are based on the premise of using A4 paper and factory default print density,
which conforms to "ISO/IEC 19752".
Toner cartridge (large): Approx. 12,000 sheets
Toner cartridge: Approx. 7,000 sheets
When the first toner cartridge is installed in a new drum cartridge, the estimated replacement cycles for the toner cartridges are as
follows (The values are not compliant with ISO/IEC19752.):
Toner cartridge (large): Approx. 10,500 sheets
Toner cartridge: Approx. 5,500 sheets
This is because there is no toner in the new image drum cartridge, and toner is drawn from the first toner cartridge.
If the [CHECK TONER CARTRIDGE/ 547:IMPROPER LOCK LEVER POSITION] message is displayed, there may be toner left in the toner
cartridge. Check that the knob of the toner cartridge does not turn in the direction of
gently tap the toner cartridge that is installed in the image drum.
About ISO/IEC 19752
ISO/IEC 19752 is a standard intended to standardize the method of measuring a toner cartridge's printable number of sheets. The
printable number of sheets and running costs of a toner cartridge based on this standard are the values obtained when continuously
printing standard data specified by ISO/IEC 19752 on A4-size paper.

Memo
The estimated number of sheets that can be printed before the [REPLACE TONER] message is displayed after [TONER LOW] is
150 sheets. (using print density with standard print pattern)
Note
The print quality deteriorates after one year following the unpacking of the toner cartridge; prepare a new toner cartridge.
Even after [REPLACE TONER] is displayed, you can continue to print for a while if you open and close the top cover; however, if
you print approximately 100 sheets (with the print density in the standard print pattern), printing completely stops to protect the
printer and the image drum. Since printing after [REPLACE TONER] is displayed causes the image drum to malfunction, replace the
toner cartridge.
