Most of the modern laser printers with the color printing functionality use single luminodiode (LED) for the printing in different colors. Thus, the paper passes the printing mechanism several times, every time for a new color laying.

Oki is a company, which is known, first of all in the printing solutions market. It develops and manufacturers monochrome and color devices for different market shares, starting from small business and up to serious corporate solutions. Recently, the company has presented several new printers and has explained the difference in the principles of their functioning.

The fact is that the company equipped its printers with several separate printing blocks for each color. Each block includes line of luminodiodes, a toner cartridge and a roll. Therefore, the printing is performed with a single pass of paper through the printer.

It makes possible to increase the speed of the printing, as there is no need for the paper to pass the printer mechanism several times. Moreover, the quality of the printing is also improved. Oki implemented a special feature of the automatic color balancing and the printing density correction. Usually, when the toner is running to the end in the cartridge, the amount of it, applied to the paper, decreases, thus, the density of the printing also reduces. Naturally, it causes the decrease in the quality of the printing. Oki equipped its printers with a special system, which periodically measures the toner density and, in case of necessity, the system makes the appropriate calibrating of the printing mechanism.

The first models of the printers, built in accordance to the new technology, are the C3200n and C5450n. These are color laser printers with the single pass document printing. Due to the technology of the printing, they have a specific construction. These printers are much deeper, as the several printing blocks are in use. At the same time, the devices are not as high as the color laser printers from other manufacturers.

The Oki printers have an integrated LCD display and functional buttons for the direct controlling of the unit. The menu options are duplicated in the Web interface, which can be accessible with the web browser application. This type of the printer's setting and controlling may become easier and more comfortable for the network use of the printer.

Both, the C3200n and C5450n models, have two types of paper feeding. There is a main paper bay for three hundred pieces of paper and a universal feeder, ensuring the direct passing of the paper through the printer. It is usually used for printing on the high density paper.

Oki supplies additional paper for the printing of visit cards. This paper has special cuts, thus, the visit card can be made very quickly and easily. Moreover, the printers include the software, offering an easy and fast way to create and print the personal visit cards. Speaking about the quality of the printing, Oki offers several drivers; each of them provides several modes for the printing in monochrome, color and photo mode.

In general, the Oki C3200n and C5450n printers are the first printers in its class, showing a real record speed in the color laser printing.
