Stepper motor overhauling method based on printer

Abstract

The invention discloses a method for checking and repairing a stepping motor of a printer. The resistance of the stepping motor is measured according to the resistance marked on the stepping motor. The stepping motor is divided into two windings, and the two windings have the same structure. The central end of a winding is symmetrically equal to the resistance of the other two ends, and is consistent with the marked resistance. The order of the lead wires of different motors is different. When measuring, you can first divide the lead wires into two groups with a multimeter, and the leads that are connected are one group. , and then use the method of measuring resistance to find the center tap end of each group. The center end should have equal resistance to the other two ends and match the marked resistance value. If the resistance value is asymmetrical or different from the marked resistance value, the motor may be damaged. The method can accurately detect the damage of the stepping motor, is convenient for maintenance and replacement, makes subsequent printing more convenient, and solves the problem that the damage of the stepping motor in the existing printer cannot be detected and the printer cannot complete the printing work.

Description

technical field [0001] The invention relates to a maintenance method based on a stepping motor of a printer. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element hits the paper, it can be divided into impact printers and non-impact printers. According to the structure of printing characters, it can be divided into full-size character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, it can be divided into serial printers and line printers. According to the technology adopted, it is divided into printers such as cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and light-emitting diode. The damage condition of th...
