OFFICE EQUIPMENT | Fax Machines

Energy consumption in different types of fax machines
There are three types of facsimile machines currently available: laser, thermal and inkjet. Laser faxes usually consume the most energy, followed by thermal faxes. Inkjet fax machines use the least amount of energy and can also use plain paper, which costs 60-80% less than thermal paper. There are large variations in energy usage between machines so you should check the power ratings for individual units.

Set energy saving features on all fax machines
Generally, a fax machine is in use sending or receiving faxes for less than 15 minutes per day; however, they are on around the clock. By purchasing energy saving features on a fax machine you ensure the energy used during idle time is down to between 15-45 watts, saving you over $25 per year. You do not miss any faxes if the machine goes into sleep mode because it is reactivated as soon as someone sends a fax. Some fax machines can also scan double-sided pages, which reduces paper costs.

Reduce paper use on the fax machine
Another way to reduce paper costs is to use a fax modem or fax card. This enables your computer to transmit and receive information and by viewing your fax messages on screen you can also save printing energy. If installed in your computer, you may not need a fax machine at all.

Energy saving hints for operating a fax machine

• Reuse paper-the energy required to produce a sheet of paper is as much as 20 times that which is used to receive and print a fax.
• Check with the manufacturer whether the fax machine you are considering can use recycled paper.
• Use electronic mail wherever possible.
• Try not to use cover sheets. Stick-on fax labels can be used on the front page to provide transmission details.
