This document introduces the development of the SE3002-DC70A series high-speed thermal printheads. The features include high speed, high quality, and high durability, achieved through a step-free structure with high performance partial glaze and highly conductive overcoat layer. The series is suitable for all types of barcode labeling printers, from direct to thermal transfer, and normal to high speed (over 300mm/s). Applications include barcode printers, label printers, packaging printers, ATMs, and ticket printers.
The SE3002-DC70A is a high‑speed thermal printhead designed for barcode, label, packaging, ATM and ticket printers. It supports both direct‑thermal and thermal‑transfer printing and can operate at speeds exceeding 300 mm/s while maintaining clear 300 dpi images.
Key features include ROHM’s STEP FREE structure for high corrosion and scratch resistance, a high‑hardness W‑coat protective layer rated for 150 km of abrasion, and an integrated history‑control function that enables high‑speed printing. The document provides the equivalent circuit, pin assignments, and a full set of electrical and mechanical specifications. This manual is written in Chinese.
