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: www.recycle-more.co.uk

  • 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.

Connect with your colleagues

Connect with your colleagues
The SCX-4645N laser printer will keep your lines of communication open by connecting everyone in the office to a single network, allowing your staff and administrators to maintain smooth, efficient printing operations. The Ethernet interface will allow you to connect the printer to this network, increasing performance and making better use of time. With a common printer for everyone there is no need to service multiple machines, meaning that your business will save time and money while your staff improve their communication skills.

Forget the manual, go automatic

Forget the manual, go automatic
The Samsung SCX-4645N has a vivid 7-inch colour LCD touch screen that enables users to begin operations simply and intuitively. Information is displayed clearly and you can access most menu options directly from the LCD itself. This logical navigation reduces operation time and increases productivity.

Massive monthly duty cycle makes it easy

Massive monthly duty cycle makes it easy
Designed to be easier to maintain than other printers, the SCX-4645N lets you focus on other tasks by delivering a consistently reliable printing and copying performance. Thanks to its unparalleled monthly duty cycle, this Samsung printer is more efficient and harder working than its competitors. It comes network-ready so it can be shared by multiple users, letting your staff have the flexibility to print to a centralised device from different desks.

Print it your way

Print it your way
Full of unique copy functions, the SCX-4645N increases your creativity and productivity. It allows you to divide the original material into full-page sections to create posters. In addition, users can save time and materials with 2 and 4-up copying. It gives you the option of producing multiple images on one page with clone copying, and to print double-sided business cards that directly benefit your employees.

Fed up with paper feeding?

Fed up with paper feeding?
Feel free to multitask while your documents print: the SCX-4645N will crank through even your biggest print jobs without relying on you for a paper refill. Upgrade the standard 620-page capacity cassette with up to 520-page and 2100-page optional cassettes for even larger capacity paper handling, perfect for all of your bulk printing needs. Sometimes, bigger really is better.

Simple scanning, no matter where it’s sent

Simple scanning, no matter where it’s sent
With the Samsung SCX-4645N, the only thing that users have to do is to choose a location for their scanned documents. Scanned files do not have to be converted, as this time-efficient, multi-function office assistant automatically processes your documents for FTP, SMB, fax, email or printing. This avoids laborious formatting processes at the same time as providing users with increased flexibility.

Great Copier with a lot of Features

This copier is great, and priced very fairly! We have had this unit for over one year and it has not posed any issues. It's not very rugged and requires your to be faitly gentile but aside form this it's agood unit and recommented.

The software and interface could be a little simplier and the support behind it isn't great but if you have patients and figure it all out it's a great machine. It also could use a better colour scanenr for the jpg's but it will suffice.
