DUAL COMPONENT TONER CARTRIDGES
These types of toner cartridges use both toner and developer. There are two
separate chambers within the toner cartridge. One chamber is for the toner
and one chamber is for the developer. Our refilling instructions will show
you which chamber is which. During the printing process, a little of the
toner is consumed with each print and is used to create the image on the
paper. The developer is not consumed like the toner but does act as the carrying
agent for the toner and is vital to the development process. Developer can
and will fatigue with use. When the fatigue becomes severe enough, it will
have a detrimental effect on the print quality. Typically, the prints will
become more and more grayish and fuzzy as the developer fatigues.
If consistent "new cartridge like" prints are not required, the developer
can be skipped every other refill. However, we strongly recommend that it
be installed on the first refill to replace the original developer that came
in the cartridge. Replacing the developer on the first refill is especially
important when refilling starter cartridges.
