Types Of Toner Cartridges And Numbers Of Pages That Can Be Printed With Them - Oki B820N Setup Instructions

Types of Toner Cartridges and Numbers of Pages that Can be Printed with
Them
The life expectancy values for the toner cartridges are based on ISO/IEC19752, converted on an A4
paper size basis for the factory default print density setting.
The standard toner cartridge is the same as that supplied with your product.
The toner cartridge (large) contains an increased amount of toner.

Toner Cartridge Life Expectancies
Toner Cartridge
Toner Cartridge (Large)
The toner cartridge life expectancies are provided for printing at the print density of the ISO/
IEC19752 standard print pattern and in general use (three pages per job). The numbers of pages
that can be printed with the toner cartridges are substantially smaller than the above expectancies
for printing one page per job or at a high print density.
• The toner cartridges lower print quality one year or more after they are unpacked.
Note!
• Use genuine Oki Data original consumables to ensure optimum performance of the product.
When using a non genuine Oki Data original consumable, the product may not deliver its optimum performance, as
well as lowering its print quality.
Even during the warranty period, Oki Data with charge deals with troubles that may arise with use of a non genuine
Oki Data original consumable (although not all non genuine Oki Data original consumables cause a trouble when used
for the product, note this enough in use of them).
• The printer may transiently output light images directly after the toner cartridge is replaced. After the printer
performs printing for a while, it recovers.
• The printer may fairly infrequently produce darker print images when using the toner cartridge for a long period.
Set [DARKNESS] to [-1] or [-2] through MAINTENANCE MENU on the printer, or set and adjust [Printer Darkness] in
your printer driver to [Light] or [Medium Light]. After the printer's toner cartridge is replaced with a new one, put the
setting for the option back to the original one.
• After displaying [TONER LIFE], the printer can still perform printing operation on approximate 20 pages through
opening and closing the top cover and, after the toner cartridge runs out of toner or the printer prints a predetermined
number of pages, the printer cannot perform printing to protect itself. In such a case, replace the toner cartridge.
• If a used toner cartridge/image drum is exchanged with one of another machine, the quantity of the used toner is not
counted normally.
※About ISO/IEC19752
ISO/IEC19752 is a standard that aims to standardize the methods for
measuring the numbers of pages that can be printed with toner cartridges.
Defined by the standard, the numbers of pages that can be printed with
toner cartridges as well as the operation cost are values measured by
printing ISO/IEC19752-defined standard data continuously on A4 size paper.
The life expectancy before [TONER LIFE] after displaying [ORDER TONER] is
Memo
approximately 250 pages (at the print density of the standard print pattern).
