Purchasing guidelines for copiers and printers, etc.

Hvis de strømslugende maskiner ikke er sat til at gå i elsparetilstande, eller hvis elforbruget er for højt i elsparetilstandene, kan man let spilde flere tusinde kroner på elregningen hvert år for hver maskine. For de større maskiner er der nu krav til elforbruget i alle tilstande.

Produktgruppen er opdelt i:

• Kopimaskiner, printere, multifunktionsmaskiner og fax-maskiner med varmeteknologi og digitale duplikatorer af standardformat: Heri er de typiske større maskiner af laserjettypen og lignende til brug i kontorer.
• Andre printere, kopimaskiner, multifunktionsmaskiner, fax-maskiner, skannere og frankeringsmaskiner: Heri er alle andre produkter blandt andet inkjet-printere, stor-format-printere, skannere og frankeringsmaskiner.

Indkøbskrav kopimaskiner, printere, multifunktionsmaskiner og fax-maskiner med varmeteknologi og digitale duplikatorer af standardformat
Krav svarer til: Energy Star gældende fra 1. april 2007

The requirements apply to products connected to mains electricity or a data link. Power consumption is typically based on weekly consumption measured according to the test method and is the maximum permitted for energy efficient. Printer technologies covered include: Electro photography, direct thermal, solid ink, dye sublimation, thermal transfer and stencil. If the machine has a digital front end powered by the machine, the power used by the controller in active mode is deducted from the machine’s weekly consumption.

Notes and additional definitions – copiers, printers, multifunction and fax machines with rapid fusing technology, and standard format digital duplicators
(1)  Where a machine is powered by an external power supply covered by the Trust’s purchasing requirements, the power supply must comply with these requirements.

(2)  Where a machine is supplied with a digital front end with a separate power supply, the device must comply with the Trust’s requirements for computers.

(3)  Photocopiers, printers and multifunction machines (monochrome) with speeds of 15 to 44 pages per minute must be supplied with an automatic duplexing unit as a standard function or as an add-on at the time of purchase. Automatic duplex must be a standard feature on machines that print 45 or more pages per minute.

(4)  Photocopiers, printers and multifunction machines (colour) with speeds of 20 to 39 pages per minute must be supplied with an automatic duplexing unit as a standard function or as an add-on at the time of purchase. Automatic duplex must be a standard feature on machines that print 40 or more pages per minute.

ENERGY STAR Program Requirements for Imaging Equipment (Version 1.0) provides a complete description of the scope and definitions.

Purchasing requirements for other printers, copiers, multifunction and fax machines, scanners and franking machines

Requirements conform to Energy Star specifications effective from 1 April 2007.

The requirements apply to products connected to mains electricity or a data link. Power consumption is the maximum permitted for energy efficient equipment. If the machine has a digital front end powered by the machine, the power used by the controller in active mode is deducted from the machine’s sleep mode consumption.

Notes and additional definitions – other printers, copiers, multifunction and fax machines, scanners and franking machines
(1) Power consumption in sleep mode applies to a product’s basic functions. In addition, there will be 1 or more extra functions which are allowed to use extra power apart from consumption by basic functions. This includes connection to a computer or network, disc drive and scanner lamp.

(2) 2 watts if fax is built-in.

(3) Standby requirement does not apply to large format scanners.

(4) If a machine is powered by an external power supply covered by the Trust’s purchasing requirements, the power supply must comply with these requirements.

(5) If a machine is supplied with a digital front end with a separate power supply, the device must comply with the Trust’s requirements for computers.

(6) Products must be supplied with the sleep mode set to activate within a given period of time depending on the size of the machine.

ENERGY STAR Program Requirements for Imaging Equipment (Version 1.0) provides a complete description of the scope and definitions.

The Table below shows the values which can be added to the sleep consumption. A function which is active in sleep mode is called a primary function. Electricity consumption covering a maximum of 3 primary functions can be added to sleep consumption. A secondary function is a function which is not active in sleep mode. Most functions are secondary functions.

The products listed in the Table below must be configured at the time of delivery to go to sleep within the time specified. The maximum elapsed time should not exceed 4 hours.

Good advice on purchasing and operating equipment

• Choose equipment that meets rather than exceeds your needs.
• Choose machines which warm up quickly to operational mode and with good energy-saving functions.
• If the product has an external power supply fitted, the power supply must comply with the requirements for power supplies.
• Whenever possible, choose a model with duplex functionality (double-sided printing and/or copying). Configure the equipment to automatically print or copy in duplex, or persuade staff to use the duplex feature. Several tons of paper can be saved over the machine’s lifetime, with twice as much space available on the shelves.
• Make sure that machines are configured with sleep mode set to activate automatically in the shortest possible time acceptable in relation to warm-up time.
• Check whether you need to have a conventional fax machine in situations where you can use a multifunction machine with a built-in fax or a fax modem on a server, which is permanently switched on anyway.
• Choose a scanner that has a separate on-off switch. Where this is not possible, connect the scanner to a separate plug which users can easily switch on and off, once persuaded to do so.
• Set the timer controls to switch off machines automatically at the end of the working day, or influence user behaviour so the last person leaving the office turns off all machines.
