Fusing the toner into the paper finishes the process. This is done by a set of fusing rollers that apply heat and uniform pressure to the paper and toner.

The toner itself contains small particles of plastic that allow for better fusing into the paper. This is the reason printed pages are warm when they come out of a laser printer.

WARNING: Fuser rollers get extremely hot. You should always let a laser printer cool down before putting your hands in it.

Knowing the six steps and the components involved in the process allows you to determine a myriad of challenges that can occur with laser printers.

For example, when you pick up a printed page from a laser printer and the toner falls off of it, you may deduce that the fusing rollers are not applying enough heat or pressure to fuse the toner into the paper.

Many of these components used in the laser printing process are contained within the toner cartridge itself.

The cleaning blade, toner, developing roller, and the photosensitive drum are all contained within this cartridge.

The cartridge can be easily replaced should any of the components fail or if the toner runs out.

This makes toner cartridges one of the most environmentally friendly components used in the computer industry.
