1. Are you
using genuine Brother toner cartridges?
you are using a refill or non-Brother toner cartridge, you should install a
Brother toner cartridge. Since Brother is not the manufacturer of the
toner cartridge you are using, we cannot guarantee or troubleshoot the
performance of the toner. Using non-Brother drum units and toners may
affect the hardware performance, print quality and machine reliability.
Each Brother laser printer is designed to work at pre-set temperatures that are
matched exactly to each of our individual toner formulations. Each
individual component is designed to work with the others to ensure quality and
reliability. Brother strongly recommends that customers use only genuine
Brother drums and toners for best results.
2. What types
of documents do you typically print on your machine? For
documents (such as letters and memos)
(such as photos or Internet pages)
3. What is
the average size of your print jobs? For example, do you typically print
one or two page jobs a few times throughout the day or do you print larger print
jobs more frequently throughout the day?
Our toners are
produced with a specific amount of toner to yield the following:
TN Starter Toner
cartridge - approx. 1,000 pages (Letter)*
cartridge - approx. 2,200 pages (Letter)*
TN210Y cartridge - approx. 1,400 pages (Letter)*
toner yield is in accordance with the testing protocol called ISO/IEC 19798
(Letter). The testing protocol involves, among other things, continuous
printing of a 5% coverage sample page of text. Users who typically print
one or two-page jobs or who typically print documents with a toner coverage
higher than 5% should expect to receive a lower page yield.
The actual amount
of pages you get out of a toner cartridge is dependent upon multiple
- What you
print (small memos, long documents, graphics, spreadsheets/reports)
- The amount
of toner coverage on a page
- The size of
each print job (number of pages per print job)
typically get the maximum yield from a toner cartridge by printing at about 5%
coverage which is a short memo or letter with approximately 150
characters. Print jobs with graphics, charts and/or large amounts of solid
coverage will use much more toner and will reduce the page yield of a toner
- You also
typically get the maximum yield from a toner cartridge by printing larger,
continuous print jobs (many pages printed with one print command), rather than
numerous small print jobs (one or two pages printed with one print
command). Because we want to ensure the highest quality print from the
machine, toner life is not only detected by the amount of toner in the
cartridge, but also the number of rotations of developer roller inside the toner
cartridge. The development roller performs additional rotations for the
first page of each print job. This means the life of the toner cartridge
varies according to the average number of printed pages per job. As the
number of rotations of the developer roller increases, the chemical properties
of the toner change and the possibility of poor print quality increases.
So, if the developer roller reaches its upper limit of rotations, the machine
will indicate "Replace Toner" even though there is toner left in the toner
