Problems solved by technology

However, LEDs and optical sensing devices, which are very difficult to manufacture, must be installed on the printer, and an analog-to-digital converter (A / D converter) circuit must be installed to interpret the signal received by the optical sensing device, so the hardware will be increased. the cost of
At the same time, when the type of surface reflected light is not within the range defined in advance by the printer manufacturer, the recording medium cannot be judged.
Therefore, if you use paper other than the standard recording medium specified by the printer manufacturer for printing, automatic identification cannot be performed, and the printing quality cannot be guaranteed.

Embodiment Construction

[0024] figure 2 It is a block diagram of the automatic recognition system for printer recording media of the present invention, which is used to detect at least two different recording media when a printer is printing, and the at least two different recording media have different load characteristics. The system includes a transmission device 210, a driving device 220, an optical encoder 230, an optical sensor 240, a processing device 250, an amplifying device 260, a position pulse counter 270, an optical detector 280 and a Non-volatile memory device 290 .

[0025] The conveying device 210 is used for conveying at least two different recording media. The driving device 220 is coupled to the conveying device 210 for driving the conveying device 210 , and the driving device 220 may be a motor.

[0026] The optical encoder 230 is disposed on the conveying device 210. When the conveying device 210 conveys at least two different recording media, the optical encoder 230 generates...

Abstract

An automatic recognizing system for the record media of printer in composed of a transfer unit for transferring different record medium, a driver, an optical encoder on said transfer unit for generator the position signal of record medium, an optical sensor for sensing said position signal, and a processor for receiving said position signal and distinguishing different record media from each other.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an automatic identification system and method for printer recording media. Background technique [0002] Current printers, whether laser or inkjet, can usually print on different recording media such as plain paper, photo paper, transparencies, and the like. For different recording media, in order to achieve better printing quality, usually different printing methods must be adopted. For example, photo paper and plain paper have different ink loading capacity. Photo paper can hold much more ink per unit area than plain paper. Therefore, even if the printed images are the same, different colors must be used for photo paper and plain paper. processing, halftones, and even different dot stacks to produce good print quality on both photo and plain paper. [0003] In the past, the type of recording medium is determined by the user. After the user determines the type of recording me...
