Title:
PAPER FEEDING PRECISION CALIBRATION METHOD AND CALIBRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/226960
Kind Code:
A1
Abstract:
A paper feeding precision calibration method and calibration system. In the calibration method, the paper feeding distance is corrected by correcting the number of micro steps comprised in a full step. By adoption of the technical solution, each full step can be compensated, and printing content data is segmented according to each full step, so that the uniformity of printing content can be ensured, local elongation or compression can be effectively avoided, and excellent printing quality can be ensured. In summary, by adoption of the technical solution, calibration compensation can be performed on the paper feeding precision problem caused by the outer diameter error of a rubber roller, and the manufacturing difficulty of a printer is reduced; moreover, the worn or aged rubber roller can also be calibrated, thereby extending the service life of the rubber roller. In addition, for the paper feeding precision problem caused by changes in the thickness and friction coefficient of paper itself, the paper feeding precision of the printer can also be recovered by the technical solution.
