Recycling Batteries Responsibly

  • The European Directive on Batteries and Accumulators aims to minimise the impact of batteries on the environment and encourage the recovery of the materials they contain. In the UK, regulations on the recycling of batteries and accumulators (rechargeable batteries) were Introduced in 2009. The Waste Batteries Regulations aim to significantly increase UK collection and recycling of used portable batteries from 3% in 2007 to 25% by 2012, rising to at least 45% in 2016.

  • The battery symbol on a product or on its packaging indicates that the product must not be disposed of with general household waste. Instead, it is the consumer’s responsibility to dispose of their waste batteries at a designated collection point so that they can be recycled. The separate collection and recycling of batteries at the time of dispo sal will help to conserve natural resources and ensure that they are recycled in a manner that protects human health and the environment. A comprehensive list of battery recycling centres can be obtained from:

  • All Samsung products that are subject to the Batteries Directive are compliant with the UK battery and accumulator Requirements. In accordance with national law, SAMSUNG Electronics (UK) Ltd is a member of an approved batteries producer compliance scheme. This scheme collects, treats and disposes of batteries on Samsung’s behalf.

Cut job times with fast scanning and printing

Scanning itself takes less time too. You can now enjoy the fastest duplex scan speed of any multifunction device – an impressive 70ipm. And forget waiting forever for printouts. With an incredible 38 pages printing per minute it’s the quickest printer and copier around.
Save time with reliability that won’t let you down

Save time with reliability that won’t let you down

Busy businesses can’t afford to waste time with unreliable products. That’s why our innovative anti-jam technology stops stress-causing device blocks by using a roller that provides a backward friction during the paper pickup process. We’ve also increased the MCBF (Mean Copy Between Failure) to 150000 (1.5 times longer than other MFPs competitors). And with a monthly Duty Cycle of 200000, productivity is kept steady and reliable.
Enjoy quality printouts

Enjoy quality printouts

Samsung’s unique ReCP (Rendering Engine for Clean Page) Technology and effective 1200 dpi improve the overall quality and vibrancy of your colour printing, ensuring every printout looks perfect. It automatically sharpens the focus of both graphics and text, while solid objects are overlapped to eliminate white gaps.
Polymerized toner

Polymerized toner

Our newly developed polymerized toner has smaller and more uniform particles than conventional toner. Your output will have crisper lines and more vivid colours, in addition to eliminating paper curling. Also, its higher wax content improves the image gloss and enhances the durability, preventing unwanted fading.
Separated, interchangeable consumables

Separated, interchangeable consumables

With separated Toner,OPC and a Developer unit, your company can reduce maintenance costs. Also, because the OPC (Organic Photo Conductor) Drums are common for all colours, they are inter-changeable, reducing your cost in terms of inventory control.
Low power consumption

Low power consumption

With its ingenious All-in-One board, overall energy consumption is kept low by minimising power requirements. In fact, compared to a conventional board it reduces TEC (Typical Electricity Consumption) by up to 42%. Meanwhile, Samsung Instant Fusing System (IFS) technology helps you print and copy faster, use less energy, and reduce energy costs.
