Making copies the Energy Efficient Way
By: Chris Kent
Pop quiz: Does your home/office imaging equipment (printer, copier, scanner, etc.) have the ENERGY STAR label? If it does, consider yourself a very smart shopper. On average, imaging equipment that is ENERGY STAR certified is 40 – 55 percent more efficient than a standard model. From copiers and printers, to fax machines and scanners, imaging equipment accounts for some of the first products to ever earn the ENERGY STAR label. As these products grow in use in homes and offices across the country, EPA’s ENERGY STAR program continues to make strides in making them more energy efficient.
Through the years, EPA has strengthened the energy efficiency requirements so that models meeting the latest requirements will be more energy efficient than ever. Now, by meeting requirements to enter low-power “sleep” modes when inactive, and using efficient power supplies, an ENERGY STAR certified copier saves energy when it is in use AND when it is not.
Looking for ways to cut down your imaging costs even more? Consider purchasing an all-in-one device the next time you are in the market. An all-in-one device (or multifunction device) that meets ENERGY STAR requirements can result in significant energy and paper savings for businesses. The multifunction device typically performs two or more functions (scan, copy, print, fax) housed within one unit. By comparison, with single-function devices every piece of networked equipment uses electricity, even when it is not in use. But by combining these functions into one device, you can save on electricity costs by reducing the number of devices into one integrated unit. Also, these multifunction devices are where industry is incorporating innovative energy saving technologies, so despite having multiple functions, a multifunction device may actually use less energy than a comparable single function unit.
If your printer/copier/multifunction device is older than 5 years, it is likely that your printer’s energy consumption is about 50% higher than a new machine. Industry continues to make great strides in improving the energy performance of imaging equipment and ENERGY STAR continues to revise its requirements to recognize these top performers.
Some features that save on energy, paper and ink costs include:
- Sleep mode and automatic shut off: ENERGY STAR products are required to automatically go into a reduced power state after a specified period of inactivity. This provides great energy savings.
- Automatic double-sided printing/duplexing: Automatically setting a printer or multifunction device to print double sided saves up to 50% of your paper usage. Printer and multifunction devices that can produce images on both sides of the paper by automatically flipping the paper make it easier to produce a double-sided page, which cuts down on paper use. Paper is the largest energy impact associated with printing, and in most cases, making this change does not cost anything additional.
- Various quality settings: Many units have more than one quality setting and using a lower quality or draft mode when printing draft or internal documents can save ink.
- Color vs Monochromatic: Printing in color generally does not use any additional energy than printing in monochromatic. But you can spend more on ink depending on the machine you choose. Units that use one cartridge for all colors tend to waste more ink than units with individual color cartridges. This is because colors are used at different rates, but the cartridge must be replaced once any one color has run out.
When looking to buy a new printer or multifunction device, go the ENERGY STAR Imaging Equipment product finder to find the right product for your needs. And remember, think before printing.
