Methodology

Topten (Best products of Europe) presents the most energy efficient black-and-white (monochrome) and colour multifunction laser printers for the standard paper size (A4 and A3) with a maximum printing speed of 100 pages per minute, of Europe.

Technical criteria

In order to be displayed on www.topten.eu, laser multifunctionals must

  • Actually be available in at least one European country
  • Be registred at Energy Star or meet comparable requirements
  • Be able to print on recycled paper
  • Have an energy efficiency index according to the following scheme:
b/w colour
Speed (ppm)     
Maximum Efficiency Index Maximum Efficiency Index
1 - 20 45% 40%
21 - 40
 35% 30%
41 - 100
 40% 40%

Data sources

  • Producers’ declarations, found in catalogues and on the web or on request
  • Declarations by ‘Energy Star’
  • National data-bases and Topten-sites such as www.topten.ch

Order of presentation

Products are ranked according to their efficiency index, which has been calculated by topten. The order of presentation can be changed by clicking the tables’ headings.

Glossary

Brand, Model, Similar Model

Products of similar construction or identical technical values are displayed only once. Clicking in the column makes the specific brands and models visible.

Electricity costs (€ in 5 years)

Assumptions:

  • Costs for electricity during 5 years (device’s mean life time)
  • According to the standardised Typical Electricity Consumption (TEC )
  • Tariff of electricity: 0.15 €/kWh. (This should be understood as order of magnitude as there can be large differences depending on country or electrical utility.)

Speed monochrome/colour (ppm)

Maximum number of pages (A4) to be printed per minute (pages per minute = ppm).

Power Sleep (Watt)

Power input when in the Sleep mode, in Watt.

TEC (kWh/week)

The Typical Electricity Consumption (kWh/week) is measured according to the standardised methodology of Energy Star for office equipment. Only products with a TEC below a certain value are labelled with the Energy Star.

Energy Efficiency Index (%)

The Energy Efficiency  Index (EEI, in %)  is calculated by Topten based on the product’s TEC and Energy Star’s TEC limit value:  EEI= TEC*100/TEC limit value. The lower a product’s EEI, the better is its energy efficiency.

Paper size

Maximum paper size.

Paper capacity (sheets)

Standard paper supply in number of sheets. Usually there is the option to significantly increase it for a somewhat higher price.

Print memory (MB)

Standard Random Access Memory (RAM), in Megabytes (MB).

Two-sided output

Also called duplexing: capability to print on both sides of a sheet.
Yes = this mode is as a standard included in this product.
No = this mode is not contained and cannot be integrated into this product.
Option = this mode can be integrated  to the product for a higher price.

Functions / Options

C = Copy, P = Print, S = Scan, F = Fax

Available in countries

This item displays the availability of models in European countries according to producers’ declarations, national Topten sites. "EU" means all countries of the European Union. However, the availability is sometimes difficult to define precisely depending on retailers' selling decisions or if the supply is stated as possible on catalogues but there is no marketing for specific products in some countries.
"On demand" means, that producers could not indicate the availability and that consumers have to ask in their countries on their own. The country codes are according to ISO.
