The life of the toner container will vary according to the density of print in your documents. If you
print documents with an actual toner coverage of approximately 5% (A4 or letter size, landscape
feed and with the Ecoprint mode* turned off), the toner container will need replacing approximately
once every 10,000** pages (A4 or letter size, 20,000 pages with the TK-20H.)
* Turning the Ecoprint mode ON conserves toner. Refer to Chapter 2 for details.
** In the case of a new printer in which a toner kit has been installed for the first time, the number
of pages that can be printed will be 5,000 or less.
