Laser Printing Features: Reliable and Efficient, but Cost High.

   In principle, laser printing uses laser heating to transfer carbon powder through the drum to the carrier, thus printing the image, and its consumable parts are divided into two parts: light drum and toner. The manufacturers, of course, are also aware of the ability to achieve  precise cost control by the research and development of consumable technology, and they have come out  a variety of different designs.

●Drum and Powder Integrated

Most of the black and white laser printers use a drum - powder integrated design. If the toner is exhausted, the user needs to replace its consumable components as a whole. This design simplifies  the maintenance of changing the the printer consumables  and reduces the cost for daily maintenance  of the equipment.

●Drum and Powder Separated

Some of the manufacturers think that the drum cartridge and toner cartridge for the printing consumables can be designed separated. Especially for the color laser equipment , different colors have different consumption.  This  design can change whichever color as needed and minimize the waste of consumables.

●Supply by Demand

The so-called "supply by demand”is  that, through the internal mechanical structure, we can evolve the original cartridge into the powder bin. With toner consumption, new toner in the powder bin can be added in  the developing unit according to the needs. The powder in the bin  keeps fresh all the time so as to avoid deterioration due to touch the air prematurely. Intuitively, the volume of the bin becomes smaller, but the printing capacity maintain the same, meanwhile , it can reduce the purchase cost of the user and lower the original consumables usage threshold .
