1.2 Protecting the Environment . . .

Minolta supports the challenge maintaining the environment and does allthat it can to actively participate in preventing and resolving ecologicalproblems. Our production is certified with ISO 9000 (quality management)

and ISO14001 (environment management).Takeback and Reutilization

Used devices, empty toner and drum units and used toner and drum unitsare taken back by a local MINOLTA partner and reprocessed for recyclingand reutilization of materials. For more information, call 08 00 / 6 46 65 82(free of charge).

What is Energy Star?

After long periods of idleness, Energy Star

copiers switch to EnergySaver Mode or turn themselves off. This allows a yearly decrease inelectricity costs of up to 60%.

Copiers with a high copying speed automatically switch to 2-sided copyingmode. This reduces the costs for copy media and the volume of paperconsumed.

Did you know that manufacturing a sheet of paper requires 10 times asmuch energy as making a copy?

The conservation of paper thus also has a direct global effect on theconservation of energy.

This copier complies with the Energy Starenergy efficiency criteria.

Use of Recycled Paper

This unit is suited for processing recycled paper that meets therequirements of ENV 12281 or DIN 19309. For details, consult your localMINOLTA partner.
