2) Factors affecting toner consumption
Standard number of output pages per cartridge shows the average number of output pages under
the condition that the data of print ratio 6% is printed on the standard paper size (A4/LT) at a normal
temperature and humidity.
However, users do not always print under the above condition. As for the type of original, copy/print
mode and environment, each user has different tendency, and as a result, the number of output
pages per cartridge becomes different depending on the user.
The major factors affecting toner consumption are as follows:
- Original/Data coverage
- Original/Data density
- Original/Print mode
- Density setting
Also there are other factors in addition to the above, such as environment, individual difference of
equipment, difference in lot quality of materials, toner density and drum surface potential.
The general relations between the 4 factors mentioned in the previous page and toner consumption
per output page in the Copier Function are as follows:
