Device and method for controlling imaging component working in printing system

Abstract

The invention discloses a device and a method for controlling the work of an imaging component in a printing system, and aims to solve the problems that a plurality of paper existing signals coexist, the paper existing signal is lost, or a plurality of paper existing signals simultaneously drive the imaging component to work in the prior control device and the method thereof. The device for controlling the work of the imaging component in the printing system comprises a sensor, an encoder, an interval counter and a pulse counter which are respectively connected with the sensor and the encoder, and a comparator respectively connected with the interval counter and the pulse counter. The control method comprises the following steps: the paper existing signals are generated; the pulses for recording the paper transmission distance are generated; the number of the pulses between two continuous paper existing signals is counted; the real-time counting is performed to the pulses; whether thenumber of the pulses between the two continuous paper existing signals is equal to the real-time count value is compared, and when the two values are equal, the imaging component is started. The invention is used for controlling the imaging component in the printing system.

Description

technical field [0001] The invention relates to a device and a method for controlling an imaging component to perform printing actions in a printing system. Background technique [0002] Inkjet printing and laser printing are currently the most widely used printing technologies. Ink-jet printing includes continuous ink-jet printing and on-demand ink-jet printing, where on-demand ink-jet printing refers to the piezoelectric crystal in the nozzle when the substrate (such as paper) reaches a predetermined position Generate a pulse to squeeze out the ink, and directly spray mist ink droplets on the surface of the substrate (such as paper); or use a micro-resistor to rapidly heat a thin layer of ink, so that a small part of the ink evaporates and forms bubbles, which pass through the nozzle , spray the ink and the air in the ink channel to the substrate at a high-speed frequency. [0003] The working principle of laser printing is that the photosensitive drum generates a charg...

Problems solved by technology

To use such a large number of delay circuits in the controller of the actual inkjet printing equipment control device, on the one hand, it will greatly increase the cost of the control device; on the other hand, due to limited resources and other reasons, many inkjet printing equipment control device, it is difficult to implement a delay circuit with such a large number of stages
