AI Technical Summary

Technical Problem

The anti-static design of traditional printers results in a cumbersome and complex structure, which affects the convenience of assembly, disassembly and maintenance, and makes it difficult to effectively discharge static electricity, which can easily lead to malfunctions or damage.

Method used

The design employs a compression spring and a conductive assembly to ensure that the printhead assembly fits snugly against the roller assembly and is grounded via a wire. The conductive assembly includes a conductive plate and an abutment arm to effectively discharge static electricity. The compression spring is a V-shaped spring to increase the contact area and elastic movement space.

Benefits of technology

It simplifies the printer's structure, improves assembly and maintenance efficiency, ensures effective static electricity discharge, avoids malfunctions and damage, and improves print quality.
