Automatic identification system and method for printer recording medium

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, etc. 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 was determined by the user. After the user determined the type of recording medium, he...

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 by the printer manufacturer, the recording medium cannot be judged.

Therefore, if you use paper other than the standard recording media specified by the printer manufacturer for printing, automatic identification cannot be performed, and the printing quality cannot be guaranteed.
