Embodiment Construction

[0014] see figure 1 , figure 1 It is the characteristic diagram of photosensitive circuit of PR2E printer. The abscissa in the figure is the driving current, and the ordinate is the A / D sampling value of the output voltage after photoelectric conversion, and the unit is mv. As shown in Table 1, the driving current is divided into 16 levels from small to large, but because the values ​​​​of the 7th and 8th, 9th and 10th are very close, it is useless to remove the 7th and 10th. Therefore, only 14 gears are used now, and each gear current corresponds to an output voltage. According to the above curve, it is easy to judge whether the printer feeds paper. The greater the gap between the voltage without paper and the voltage with paper, the easier it is to judge whether the printer feeds paper, that is, the stronger the environmental adaptability of judging paper feeding.

[0015] Through the principle and characteristic diagram of the photosensitive circuit, we can find that wh...

Abstract

The invention discloses a method for regulating a drive current of a photosensitive element of a PR2E passbook printer. The method comprises the following steps of: acquiring output voltage of each range of drive current photosensitive element and comparing output voltage values corresponding to the adjacent drive currents to acquire the drive current of an inflection point; setting the drive current as a maximum range of current and recording the output voltage value of the photosensitive element in the maximum range of drive current; and comparing multiple relation between the output voltage of the inflection point and the output voltage in the maximum range of drive current, judging whether the inflection point is shifted leftwards or rightwards according to the multiple relation and accordingly regulating the drive current. The method has the advantages of adaptively regulating the drive current of the photosensitive element of the printer, making the printer keep relatively higher paper detection sensitivity and improving the printing efficiency of the printer when the paper detection sensitivity of the printer is reduced because of the change of the service environment of the printer.

Description

technical field [0001] The invention relates to a method for adjusting the driving current of a paper photosensitive element of a PR2E passbook printer. Background technique [0002] The PR2E passbook printer is a commonly used printing device in the banking system. During the use of this PR2E passbook printer, sometimes there will be a problem that after the paper is inserted, the printer cannot detect the paper and directly returns the paper. Greatly affect the efficiency of operating staff. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the PR2E passbook printer, the present invention provides a method for adjusting the driving current of the photosensitive element of the PR2E passbook printer paper, which can greatly improve the paper detection sensitivity of the PR2E passbook printer. [0004] The technical scheme that the present invention solves the problems of the technologies described above comprises the following ...
