Page 4: Introduction
Advanced Printing Systems 1. INTRODUCTION The SS205-V4+ LV (Super small 205, version 4+, high speed) is a new improved version of latest SS205-V4 optimized for low cost application. It is also compatible with SS205-V3. The SS205-V4+ LV printer has been designed to be the smallest, wide voltage range (from 3.0V to 9.5V), and high efficiency easy loading printer on its market. -

For good print quality, it is advised to keep the current into the windings between two successive dot-lines. It is also recommended to have a few dot lines not printed at motor start to avoid print compression effect due to play take-up into gear box. SS205-V4+ LV - Technical Manual - Rev B Page 13... -
