2.10 Adjusting the Print Density
Print density is the term used to describe the relative thickness of the line
used to print characters. The thickness of a line is known as the line weight.
The print density adjustment controls the amount of toner applied to the
paper to make the line weight thinner or thicker.
You can significantly extend the life of an Electrophotographic Supply (EP-
S) cartridge by setting the print density adjustment dial to the highest
possible number (lightest setting) that gives you acceptable print quality.
For most applications a print density setting of 7 can be used to produce
high-quality print, and extend the life of the cartridge.
NOTE: The EP-S cartridge life can be up to 4,000 A4 or letter-size pages.
This specification is based on 4% toner coverage with the print density set
at 7.
You can check the line weight thickness by printing the Engine Test Print
after performing the adjustment (see Section 2.11).
Use the following procedure to adjust print density.
1. Press the release button forward and then down.
— The top cover releases and opens slightly.
