HEALTH AND SAFETY

INTRODUCTION
Domino supplies Safety Data Sheets (SDS) giving specific safety
information with each of its ink, make-up and wash fluids. There are also
warnings on each container. The following notes are for general guidance
only.
Basic Requirements
When used correctly, printing inks do not cause problems. However,
everybody using them should be familiar with the appropriate safety
standards and be aware of the precautions that should be taken. The
following are basic requirements:
• Proper standards of industrial practice relating to cleanliness and
tidiness must be maintained.
• Inks and their containers must be stored and handled with care.
• Do not smoke or allow naked flames (or other sources of ignition) in the
vicinity of any inks or solvents as this is highly dangerous.
• All who come into contact with inks must be properly instructed in their
use.
Directions for safe working practices vary according to the environment.
The following are broad principles so that necessary precautions may be
taken:
• Contact with the mouth must be avoided. Therefore eating, drinking or
smoking, or any personal habits or actions which may transfer ink to
the mouth, must be avoided.
• Contact with the eyes must be avoided. Suitable eye protection must
always be worn whenever there is any risk of splashing or misting. If
ink does get into the eyes, first aid treatment is to flood the affected
eye for 15 minutes with saline solution, (or clean water if saline solution
is not available), taking care not to allow the water to run into an
unaffected eye. Medical aid must be obtained immediately.
• Most inks contain solvents which may injure the skin. Good working
practice must always be employed and risk assessments carried out.
Safety Data Sheets are available that give advice on personal
protective equipment. Most gloves only offer limited and short term
exposure protection and must be changed after any splashing and on
a frequent basis.
• Many inks contain materials which vaporise easily and can be inhaled.
Good ventilation and extraction is necessary.
• Any used cleaning materials, e.g. rags, paper wipes, are a potential fire
hazard. They must be collected for safe disposal after use.
• After exposure to ink, all possible traces must be washed off as soon
as possible at the nearest washing facility.

HEALTH AND SAFETY
1-4 20509 Issue 7 Jan 2018
Certain inks are allowed for use where they can be in indirect contact with
food. In these cases, the following precautions must be observed in
addition to those appropriate to hygiene:
• The inks must only be used in printers supplied from new for use with
these inks. Any repairs and replacements must use genuine, new and
unused spare parts.
• The inks must not be used in printers which have previously been
used, at any time, for any other purpose.
Storage
Printing inks must be stored in well-ventilated buildings, in areas set aside
for the purpose, chosen for safety in case of fire. Materials based on
volatile, flammable solvents must be stored in accordance with local
regulations.
Fire Risk
For an electrical fire, do not use water. If water must be used, such as in
the case of a Nitro-cellulose ink fire (see below) the power MUST BE
REMOVED first.
Many inks contain Nitro-cellulose as the binder and remain highly
flammable when dry. Observe all warnings given on the machine and the
following safety instructions:
• If there has been an accumulation of dried ink, do not use metal
scrapers to remove it, as they can produce sparks.
• If dry Nitro-cellulose based ink ignites, it will generate its own oxygen
and can only be extinguished by lowering the temperature with water.
• If a Nitro-cellulose fire occurs, ENSURE THAT THE ELECTRICAL
POWER IS IMMEDIATELY REMOVED FROM THE PRINTER BEFORE
water is used to extinguish the fire.
Fire risk is a most important consideration where printing inks are stored
and used. The degree of fire hazard will vary considerably from one type of
ink or wash to another.
Water-based inks will not burn, although inks based on water-alcohol
mixtures may burn if there is sufficient alcohol present. Prolonged exposure
of water-based systems to high temperatures may evaporate the water to
give a flammable residue.
Solvent-based inks offer a greater degree of hazard depending on the
particular solvent or solvent combination. When there is a particular hazard
the appropriate information is given on the SDS.
During maintenance, print drops may be collected in a container, such as a
beaker. It is essential that this container is made of conducting material and
is securely connected to ground/earth.
If there is a fire, there is a likelihood that dangerous fumes will arise from
printing inks. For this reason ink must be stored where it can be reached

quickly by the fire fighting service, and where it will not spread beyond the
store.
Spillages and Disposal
WARNING: Some dried inks are highly flammable. Clean up
all ink spillages immediately. Do not allow the
ink to dry or allow any build-up of dried ink spills.
Spillages must be cleaned up as soon as possible with the appropriate
solvent materials and with regard to the safety of personnel. Care must be
taken to prevent spillages or residue from cleaning up entering drains or
sewage systems.
Inks and associated fluids are materials which conduct electricity.
Therefore, power to the printer must be switched off while spillages inside
the printer cabinet are being cleaned up.
Printing inks and associated fluids must not be treated as ordinary waste.
They must be disposed of using approved methods according to local
regulations.

Print Head

DESCRIPTION

INTRODUCTION
The Macrojet 2 large character printer consists of:
• The print head (up to four can be fitted to one cabinet)
• The control cabinet
• The product detector (one or two can be fitted)
• The disposable ink supply container.
Print messages are normally entered using a Domino Pocket Terminal.
Print heads can be supplied to print with either 7 or 16 ink drops and in a
range of character heights (see page 2-7). Each is a separate stainless steel
assembly connected to the cabinet by a flexible conduit and will work in
any position. Print heads can be added or changed without difficulty.
The control cabinet contains an ink system supplying ink to the print
head(s) and an electronics control system. Controls and external
connections are grouped on a panel at the rear.
The product detector is mounted on the line and senses the product as it
approaches the print head. There are three optional types: two are infra-red
beams and a third works by metal detection.
Ink is supplied in a disposable 5 litre bag-in-box ink container, connected to
the printer by a Quick Connect/Disconnect (QCD) connector.
Messages to be printed are normally entered as serial digital data from a
Domino Pocket Terminal, but it is also possible to control the printer from a
separate computer system (details from Domino).
The printer contains a set of separate auxiliary alarm contacts which can be
connected to external indicators or other equipment. An optional alarm
beacon is also available to show the printer status.
Another option is a shaft encoder which allows the printer to follow line
speed variations. This includes the slowing down and speeding up
involved in line stop and start.
