Mono Laser Printers

Our High Quality Refurbished Mono Laser Printers come with warranty and working consumables. We have a few choices below such as A4 Mono Laser Printers and A3 Mono Laser Printers.

Below is an explanation on how Mono Laser Printers work.

The laser printing process starts with the transmission of the data from the computer or data storage device to the printer's image processor. The image processor rasterizes the data and converts the information received into a graphic image; this image is then sent to the printer's memory in preparation for 'transmission'. Meanwhile, the photosensitive drum revolves and touches the charged roller or the charged corona wire.

The wire or the roller imparts its negative charge to the drum and as a result the latter acquires a negative static charge. This static charge remains on the drum's surface as long as it's dark. At this point, the laser assembly emits a light beam onto the revolving photocell. The laser beam passes through a series of focusing mirrors so that it would hit the drum precisely. This laser beam is activated and triggered by the data stored in the image processor memory. At the points of the drum hit by the laser beam, the charge is reversed from negative to positive .

Through this process, the image is outlined and drawn on the drum by the laser beam; that is, the positively-charged portions of the revolving drum or photocell represent the complete image of the text or picture to be printed. Now, the drum or the photocell touches the negatively charged toner. This toner clings to all the positively charged portions of the photocell and leaves all the negatively charged portions alone.

At this point, the photocell bears the actual image. Next, the photocell or the drum rolls over the paper and the toner is transferred to the latter. The paper with toner then passes through the fuser assembly which bonds the toner particles to the paper. Through a combination of heat (coming from a heat source within the fuser's tube) and pressure, the toner powder (made of wax or other easy to melt substance) melts on and gets bonded with the paper. The paper then comes out printed.
