2.7.3 Pixel counter and its related code
Pixel counter
1. Outline
Pixel counter is a function that counts the number of dots emitted by the laser and converts it into the
print ratio (%) per standard paper size. This “Print ratio (%) per standard paper size” is called Pixel
count (%).
This function enables you to know how each user uses the equipment and to grasp the tendency of
toner consumption (number of output pages per cartridge).
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.
