Background

The laser printing toner boxes of brothers, fun, association and other series on the market are all provided with a detection device, when the detection device of the toner box on the machine touches a sensor of the machine, a signal is given to the machine at the same time, the machine identifies the toner box, a printing page number is defaulted, the detection device fails, when the printing amount of a user reaches the number, the machine stops printing, and when the detection device is damaged or not operated properly, the machine cannot detect the toner box, so that the toner box cannot be used.

The detection devices of BROTN2425/760, XERP235, RICSP230 and other series of products have the same structure and work reason, the most common detection devices in the industry are basically developed and designed according to the original structure, the original structure detection device is operated to the machine identification process, when a bump on the detection device touches a sensor of a machine after a carbon powder box is installed, a printing device drives a carbon powder box driving gear to rotate for about three circles (the detection assembly before three circles is not rotated), the detection device starts to rotate and is separated from the contact with the sensor of the machine, when the printer drives the driving gear to rotate for about five circles, the bump on the detection device touches the sensor of the machine, the printer finishes detection, the printer can normally use for one week life, the detection device fails, the D-shaped port of a stirring frame needs to be reset if the detection assembly needs to be reused, the original factory structure detection assembly is driven by a stirring tooth, so the reset requirement needs to align the D-shaped port of the stirring frame at a designated position, just stirring to drive the detection device to start rotating when the driving gear rotates for about three circles, then adjusting the detection device to the starting position, adding powder for reuse by many users at present, simultaneously, in order to ensure the product quality when the factory is produced, 100% of products are processed on the machine for quality detection before the factory leaves, the positions of the detection device of the carbon powder box and the D-shaped opening of the stirring frame are changed after printing, the driving gear needs to be rotated to carry out counterpoint adjustment again, the whole transmission mechanism is rotated by rotating the driving gear, the D-shaped openings of the counting gear and the stirring gear are appointed to be in positions, because the driving gear, the counting gear and the stirring gear are not at the same end, whether the specified position is reached is observed unfavorably during rotation, the transmission ratio of the driving gear, the counting gear and the stirring gear is large, and after the driving gear rotates for many circles, the positions of the counting gear and the stirring gear are changed very little, the operation is complicated, and it is difficult to ensure that the counting gear and the stirring gear are in the specified positions during production, causing the printer not to recognize the toner cartridge, and the efficiency is very low.

In addition, the existing market also has an automatic resetting structure, the machine can be reset again as long as the carbon powder box is taken out and reloaded, the carbon powder box possibly has the situation that paper is taken out and reloaded in the actual use process, the machine can be reset to zero, the printing quantity of the carbon powder box cannot be accurately calculated, and meanwhile, the carbon powder box can not be reported and stopped when being printed to be short of powder.
