Page 4: Introduction
Advanced Printing Systems 1. INTRODUCTION The ELM205-V10 printer has been designed to be the smallest, wide low voltage range (from 2.7V to 8.5V) and high efficiency (20% less consumption than standard 5V mechanisms) easy loading printer on the market. The unique easy loading APS concept makes the ELM205-V10 an ultra compact, reliable and cost- effective mechanism. -

On the above example, if the ELM205-V10 works consecutively for 15 seconds, it must rest for 22.5s to allow the motor to cool down. ELM205-V10 - Technical Manual - Rev. F Page 14... -
Page 15: How To Optimize Speed, Consumption And Max. Peak Current
MaxPS will be the invert of the activation time multiplied by the number of blocks the head is divided into. Example: at 6.5 V with the ELM205-V10, let’s set the activation time as 1.76ms. If the maximum current available for the head is 2.4A, the maximum number of dots to be simultaneously activated will be 2.4A/(6.5V/176 )=64 dots. -
Page 16: Sensors
6.2 End of Paper Sensor The ELM205-V10 has an end of paper sensor achieved by a photo-transistor. Arrange the circuitry so that no energy is applied to the head when there is no paper. If the head is energized when there is no paper and the head is in the down position, then both roller and head may be strongly damaged. -
