Multi-toner cartridge and multi-transfer printing print system for office equipment

Abstract

The invention relates to a multi-toner cartridge and multi-transfer printing print system for office equipment, which is characterized by comprising a plurality of groups of toner cartridges, toner cartridge drawing mechanisms matched with the toner cartridges, a plurality of groups of transfer printing mechanisms with the same structure, and a laser scanning unit comprising a plurality of groups of laser scanners, wherein a main-control unit comprises a main control chip and a peripheral circuit; the main control chip controls the laser scanners through a plurality of LSU control logic circuits, andcontrols charging voltage, development voltage and transfer printing voltage of a plurality of high-voltage circuits through a plurality of high-voltage control logic circuits; the plurality of high-voltage circuits are respectively connected with a plurality of OPC to perform high-voltage control; and the multiple toner cartridges and multiple transfer printing mechanisms can perform printing at the same time, so that toner cartridges of different colors can be conveniently changed according to various needs, the print cost is low, the size is small, the mounting is convenient, the number of the toner cartridges, the transfer printing mechanism components and the laser scanners can be increased as required, and multi-color printing is realized. The print system can be widely applied to printers, copying machines and fax machines.

Description

technical field [0001] The invention relates to an accessory for office equipment, in particular to a multi-drum multi-transfer printing system for office equipment. Background technique [0002] Existing office equipment (laser printers, fax machines, copiers) all print in black and white, that is, use a black toner cartridge (the first toner cartridge) for monochrome printing. The printers are used as representatives for discussion below. Traditional monochrome black-and-white printers only need a toner cartridge and a set of transfer mechanism components to achieve printing. Even for color printers, it attaches powders of various colors to the same photosensitive belt and prints them out through a set of transfer mechanism components. , and its required precision and manufacturing cost are relatively high. [0003] In recent years, with the emergence of color printers, multi-color printing has become a trend. However, color printers are equipped with a variety of sta...
