• Read the Safety Data Sheet (SDS) before storing, handling, transporting or using the ink•
cartridges.
• Protect the printer from electrical surges or low voltage conditions by using a UPS•
(Uninterruptible Power Source).
• Turn o and disconnect electrical power to the printer before making any wiring•
connections.
• Turn o and disconnect electrical power to the printer before connecting or disconnecting•
a print head.
• Make sure all cables are secured away from moving production line components.•
• Stop printing before removing and/or installing an ink cartridge.•
• Use only lint-free wipes when cleaning the cartridge nozzles.•
• Clean cartridge nozzles according to the enclosed recommendations.•

product guides.
•Do not open any enclosed components. They contain no user-serviceable parts. •
•Only use accessories that are approved by the manufacturer. •
•Dispose of batteries, electrical and electronic products separately at an appropriate •
collection point. Do not put batteries, electrical and electronic products in the normal
domestic waste stream.

INKS AND FLUIDS INFORMATION
Domino supplies Safety Data Sheets (SDS) giving specific safety information for each of its inks.
Safety Data Sheets can be found on the MSDS section of the Domino website.
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.•
•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 aected 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 unaected
eye. Medical aid must be obtained immediately.
• Most inks contain solvents that 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 oer 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 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 o as soon as possible at the nearest washing facility.
Storage
Printing inks must be stored in well-ventilated buildings, in areas set aside for the purpose and
chosen for safety in case of fire. All fluids must be stored in accordance with local regulations.
HEALTH AND SAFETY
EPT077343 EN - Issue 1 - 11 November 2022 13

Fire Risk
Observe all warnings given on the machine and the following safety instructions.
For an electrical fire, do not use water.
If there has been an accumulation of dried ink, do not use metal scrapers to remove it, as they
can produce sparks.
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 sucient alcohol present.
Prolonged exposure of water-based systems to high temperatures may evaporate the water to
give a flammable residue.
Solvent-based inks oer 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.
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 Flammable material. Risk of fire.
Do not allow ink to dry or allow any build‑up of dried ink.
Some dried inks are highly flammable. Clean up all ink spillages
immediately.
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 that conduct electricity. Therefore, the power to the
printer must be switched o while spillages 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.

ELECTRO-STATIC DISCHARGE
To avoid static discharge from production line equipment, the equipment and everything on it
must be grounded correctly. While it is not Domino's responsibility to maintain the customer's
equipment, the customer must be aware of the importance of grounding. At the time of
installation of the printer, the Domino (or Domino distributor) technician should ensure that the
line the printer is installed on is appropriately grounded. This means that all metallic items within
12 inches (300mm) of the print head location must be securely grounded. This should be
checked with respect to the print head chassis ground using an Ohm Meter, DVM or another
suitable device. It is essential that grounding is checked periodically and that if the printer is
relocated to a dierent production line, then the new production line is properly grounded.
Additional static dissipating devices, such as static brushes on the line, etc. are recommended.
