					Tendering recommendation for laser printers – environmental considerations

                             Black-and-white/colour electrophotographic printers

Criterion

Material properties

Neither polymers containing halogen nor organic chlorine or bromine compounds may be used as
flame retardants in plastic housings. This requirement exceeds the stipulations of the Electrical and
Electronic Equipment Act1, passed in compliance with the EU directive on the Restriction of Use of
Certain Hazardous Substances2.
Substances categorised according to Annex VI to the EU Directive 67/548/EEC as possessing certain
hazardous properties must not be used in the manufacture of plastics for use in housings:
Carcinogenic substances in the EU categories 1, 2 or 3,
Mutagenic substances in the EU categories 1,2 or 3,
Substances which are toxic for reproduction (teratogenic) according to EU categories 1,2 or 3, unless
it is a question of process-determined and unavoidable impurities.


Further substance prohibitions according to the Electrical and Electronic Equipment Act must also be
observed.
Plastic parts with a mass of more than 25 grams must be permanently marked as such as per ISO
11469:2000.
Plastic parts should be recyclable and may only be metallised in cases where a genuine need to do so
can be established.
Batteries must correspond to the requirements of the current EU Battery Directive.

Toners
Substances classified according to the EU Directive 67/548/EEC as possessing certain hazardous
properties may be added neither in their pure form nor as constituents of other preparations during the
manufacture of toners and inks:
Carcinogenic substances in the EU categories 1, 2 and 3 to be labelled as R 45, R 49, R 40;
Mutagenic substances in the EU categories 1, 2 and 3 to be labelled as with R 46, R 68;
Teratogenic substances in the EU categories 1, 2 and 3 to be labelled as R 60 through R 63;



Toxic or very toxic substances with the hazard characteristic T or T+.
Azo pigments which can release carcinogenic aromatic amines included in the list of aromatic amines
contained in the Directive 2002/61/EC (or TRGS 614) must not be used in toners or inks.
Heavy metals, especially mercury, arsenic, lead and cadmium and their compounds, as well as nickel
and chromium (VI) compounds must not be contained as constituents in toners and inks.
Unavoidable impurities brought about by the presence of heavy metal oxides such as nickel and
cobalt oxide are to be kept at as low a level as possible.


Safety data sheets for toners or inks must be made available on request.

Chemical emissions
The following emissions rates, defined according to RAL-UZ 122, Annex 2 as the sum of the
emissions in the standby and printing phases, must not exceed the following values in milligrams per
hour:
Colour printing (mg/h)        black-and-white          standby phase (mg/h)
                              printing (mg/h)

Energy

If the Energy Star is to be accepted as the criterion for energy-saving devices, then, at the very least,
the requirements of the Energy Star for "Imaging Devices“ of May 2006, compulsory since April 2007,
              3
are to be met .
On the basis of the requirements of the environmental label “Blue Angel”, the following apply:
Depending on the time, the power consumption of the printer after the close of printing must not
exceed a prescribed limiting curve.
This also applies to situations whereby signals which are not intended to activate a print job are
received via a data network.
Details on the level of power consumption, activation times to be observed and return times with
reference to the device type, scope of function and print speed are laid down in the annex
“Requirements on energy-saving printers and multifunctional devices”.


Accessories such as duplex installations, sorters, additional paper trays or counting installations must
not adversely affect the energy saving function. Any possible additional power consumption on the
part of the accessories can however remain unconsidered when checking whether the device is in
compliance with its limiting curve.
When the device is supplied in factory condition the energy saving functions must be activated
according to the requirements.
Each device must include an easily accessible ‘on/off’ switch.
The arrangement of switches should correspond to the IEEE 1621 standard.

Noise emissions
The guaranteed sound power level, calculated on the basis of EN ISO 7779:2001 in association with
ISO 9296:1988 is to be indicated in dB(A).

For black-and-white printing the highest permissible level, calculated using the following equation
LWad = (59 + 0,35 ∗ Sbw) dB(A)
must not be exceeded.

Similarly, for colour printing the following applies:
LWad = (61 + 0,30 ∗ Sco) dB(A)

LWad is the highest permissible sound power level in any individual case. In the case of serial colour
devices the value for black-and-white printing is taken as the reference.
Sbw or Sco are the printing speeds in pages per minute for black-and-white or colour printing as
measured during the process of determining the sound power level4.
(Note: in order to establish the guaranteed sound power level, either 3 devices must be tested or, if
only one device is tested, 3 db(A) must be added to the result).

Electrical safety, electrical and magnetic fields

Electrical safety must be tested in accordance with the EN/IEC 60950-1:2006 standard.
Requirements on the emission of electrical and magnetic fields should be met in accordance with the
preconditions for CE marking. (Interference characteristics according to DIN EN 55022, immunity to
interference according to DIN EN 55024)

 it is our recommendation to the buyer to demand proof of testing in accordance with the values prescribed in
RAL-UZ 122, Section 3.3.2.1
Packaging and information

Packaging must be easily separable into different kinds of material and designated according to the
packaging ordinance. Halogenated plastics must not be used.
The user instructions of the MFD must be available at least in the form of a paper summary in
German. More detailed documentation can be made available using other media. In addition to
technical descriptions and specifications, the documentation must contain any relevant health and
environmental information. This must include at least the following:
     Information on the careful handling of toner and ink cartridges.
     Information on energy saving, device specifications relevant to energy use such as power
        consumption in the various modes, activation times out of standby modes and return times to
        energy saving modes.
     An indication that the energy consumption can be reduced to zero upon pulling out the plug or
        turning off the power socket (e.g. when using a spreader socket) – for the cases where the
        device does not have a switch to reduce the power consumption to 0 watts.
     The guaranteed sound power level and, where appropriate, advice on where to install the
        device. At levels of more than 63 dB(A) the printer should not be located in rooms in which
        concentration is required to work.
     The indication that the device is suitable for use with recycled paper.
     Information on warranty period and the availability of spare parts
     Information on the modalities of product return after the end of its active life.

Product longevity
Replacement parts which can become necessary in the normal course of operation are to be available
for up to 5 years after the production of the device is discontinued.

Return of device at the end of its active life
If necessary, the devices are to be returned at the end of their active life to a named collection point5.

 (Note: the bidder declares that the individual requirements have been met and presents where
necessary testing documentation on the measurement of power consumption according to Energy
Star, as well as test results for noise emission measurements and a summary of the test results for
chemical emissions.
If the bidder has a RAL-UZ 122 contract for the use of the Blue Angel label for the product, then it can
be accepted without checking that all requirements have been met (with the exception of electrical
safety und electrical and magnetic fields).




5
  According to the Electrical and Electronic Equipment Act, devices used by private persons can be returned to
municipal waste disposal services. Devices used by small traders can be treated in the same way as they can
also be passed on to private end users. For all other devices an agreement should be made with the supplier at
the time of purchase.
