A preheatable toner cartridge

Abstract

The invention discloses a novel preheatable toner cartridge, which includes a drum body and a heating module, the heating module includes an L-shaped bracket, a temperature sensor and a heating chamber; the bottom of the heating chamber is symmetrically arranged with paper inlets and At the paper outlet, at least one infrared heating tube is arranged in the heating chamber; one end of the L-shaped bracket is fixed to the waste powder collection bin on the left side of the drum body, and the other end is fixed to the top of the heating chamber; the temperature sensor is connected to the L-shaped bracket fixed; the temperature sensor and the infrared heating tube are respectively electrically connected to the central controller and the control circuit of the printer. The invention adopts the structural design of the heating module and the drum body, which is not only convenient for disassembly and assembly, but also can reduce the repair and maintenance costs in the later stage; in addition, the invention improves the preheating effect of the toner, and further improves the printer's performance in low temperature environments. Printing quality, at the same time, it has the advantages of high preheating efficiency, less heat loss, and energy saving.

Description

technical field [0001] The invention relates to the technical field of printer equipment, in particular to a novel preheatable toner cartridge. Background technique [0002] Toner cartridges, also known as photosensitive drums, generally consist of a base substrate made of aluminum and a photosensitive material coated on the substrate. The toner cartridge not only determines the quality of the print, but also determines how much money the user needs to spend during use. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the print quality is actually largely determined by the toner cartridge. [0003] At present, the existing laser printers on the market have relatively strict operating environment requirements, especially relatively high requirements on the ambient temperature. For example, the Pantum P2500 black and white laser printer requires an ambient temperature of 10°C to 32.5°C, so these printers generally cannot...

Problems solved by technology

For example, the Pantum P2500 black and white laser printer requires an ambient temperature of 10°C to 32.5°C, so these printers generally cannot be used normally below freezing point

However, our country has a vast territory. In the north of our country, the temperature is lower than 0°C for a long period of time. At this time, the laser printer may need to work in an environment lower than 10°C. Often because of the short heating time of the fixing roller, As a result, the toner cannot be completely melted on the paper, causing the toner to blur or fall off; but increasing the fixing time will slow down the paper output speed of the printer

However, in some existing toner cartridges equipped with preheating devices, most of the preheating devices are integrated with the toner cartridge, which leads to inconvenience in later maintenance and high maintenance costs; in addition, its preheating efficiency is low, resulting in more waste of electric energy
