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. The rubber roller can be separated from the mechanism and fixed to the customer’s
door, allowing for a very easy integration.
The patented locking system of the rubber roller onto the chassis and easy opening lever makes the door
position and rotation axis independent of the cover position, giving the customer total freedom when
designing the housing. The ergonomically centred paper path allows uniform and aesthetic housing design.
Thus, no access to the cover’s sides is required to open the door.
1.1 ELM205-V10 Features
•Patented easy loading and easy door opening system
•Ultra compact design
•Up to 95 mm/s printing speed
•Ultra light (40g)
•Starting operating voltage (logic and dots) from 2.7V up to 8.5V
•High resolution printing (8 dots/mm)
•Life of 100 million pulses, 100 km
•Low consumption
•Low noise due to its technology (thermal)
