and generally used as 5% coverage. 5% coverage means that an A4
sided paper has about 5% image or text on it. So, if the paper or original
has complicated images or lots of text on it, the coverage will be over 5%
and at the same time, toner usage will be as much as the coverage.
scanning. Generally, more dots per inch result in a higher resolution,
more visible detail in the image, and a larger file size.
for a month. Generally the printer has the lifespan limitation such as
pages per year. The lifespan means the average capacity of print-outs,
usually within the warranty period. For example, if the duty cycle is 48,000
pages per month assuming 20 working days, a printer limits 2,400 pages
a day, which is not small amount.
It consists of two hot rollers. After toner is transferred onto the paper, the
fuser unit applies heat and pressure to ensure that the toner stays on the
paper permanently, which is why paper is warm when it comes out of a
laser printer.

Toner is a powder used in laser printers and photocopiers which forms the
text and images on the printed paper. Toner can be melted by the heat of
the fuser, causing it to bind to the fibers in the paper.
