Aligning device for passbook printer

Abstract

The invention discloses an aligning device for a passbook printer. The aligning device comprises a microprocessor, a sensor module and a paper feeding module, wherein the sensor module and the paper feeding module are respectively connected with the microprocessor, the sensor module is externally connected with a sensor, the sensor senses properties of print media and transmits property data to the microprocessor, the microprocessor carries out judgment according to the transmitted property data and sends print media inputting commands to the paper feeding module, the paper feeding module is externally connected with a paper feeding device, and the paper feeding device is used for controlling the inputting of the print media. The sensor is used for detecting paper feeding positions, the print media inputting can be carried out under the control of the microprocessor, so that positions and strokes of the print media can be controlled accurately, a phenomenon that printed information is printed on fault positions by a print head can be avoided, the print accuracy and the print efficiency can be effectively improved.

Description

Technical field [0001] The invention relates to a printer accessory, in particular, a printing paper or card aligning device for a passbook printer. Background technique [0002] The passbook printer is used to print bills in the financial system. The passbook printer is mainly used for financial industry savings and corporate accounting services, and is used for front-end customers to print passbooks, statements, deposit and withdrawal receipts, interest receipts, charge documents and other vouchers. [0003] In the working process of the passbook printer, the paper feeder controls the travel of the printing medium to be able to print passbooks, statements, deposit and withdrawal receipts, interest receipts, and charge receipts. Therefore, at the beginning of use, the passbook printer needs to be set to meet the needs of the printing medium and printing range. However, after the printer has been working for a period of time, due to various reasons, the print medium may not be ac...

AI Technical Summary

Problems solved by technology

However, after the printer has been working for a period of time, due to various reasons, there will be situations such as printing medium strokes and inaccurate alignment, which will lead to deviations in printing effects. For ordinary printing media and usage conditions, this defect can be tolerated Yes, but for important bills, the deviation of the printing position will often lead to important mistakes. Therefore, people need to control the printing position and quality of important documents. At this time, whether the printer can accurately print according to the predetermined position becomes a key factor
