HEALTH AND SAFETY HEALTH AND SAFETY INTRODUCTION Domino supplies Safety Data Sheets (SDS’ s)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.
Page 14: Storage
HEALTH AND SAFETY 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 off as soon as possible at the nearest washing facility.
Page 15 HEALTH AND SAFETY If dry Nitro--cellulose based ink ignites, it will generate its own oxygen and can only be extinguished by lowering the temperature with water 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.
Page 16: Spillages And Disposal
HEALTH AND SAFETY 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.
Page 17: Symbols
HEALTH AND SAFETY SYMBOLS The following symbols are used in this manual. Where they appear next to a procedure or instruction, they have the significance and importance of written warnings and cautions. Eye protection must be worn. Protective clothing must be worn.

The holster is mounted in the printing position and contains precision guide rails to ensure that the print head always returns to exactly the same position if the print head is removed and replaced.
Page 121: Cabinet
PRINTER DESCRIPTION Gutter. Ink caught in the gutter is drawn back into the ink system for re--use by a pump in the cabinet. The gutter system in the head consists of the gutter pipe, a short length of tube, and a gutter sensor consisting of a length of pipe electrically isolated from the chassis.
Page 122 PRINTER DESCRIPTION CAUTION The printer must not be operated with the ink chassis removed. In the lower compartment, operations such as replacing cartridges and reservoirs are carried out through the open door. However, the ink system is mounted on a chassis, enabling it to be removed as a single assembly.

PRINTER DESCRIPTION INK SYSTEM General CAUTION The Ink system must never be withdrawn from the cabinet with the printer running. The ink system supplies the printhead with ink at the correct pressure and viscosity. When the jet is stopped, the system also flushes out the print head with make--up to provide a clean stop and, when the jet is next switched on, a clean start.

Page 134 PRINTER DESCRIPTION Feed circuit. Ink from the reservoir is supplied to the circuit by the high pressure pump. The ink is pumped through a 5 micron filter, a jet pump and then through a 69 mbar (1psi) Pressure Relief Valve (PRV) and back into the reservoir.
Page 135 PRINTER DESCRIPTION through stationary ink. Its movement down the tube is timed and this time is used as the viscosity check. If the ink is too thick, make--up is added into the ink reservoir by opening the make--up solenoid valve. The suction provided by the low pressure (gutter) pump head then draws in make--up from the make--up reservoir and passes it with the gutter ink into the reservoir.

MAINTENANCE 10. Pressure Window Check The pressure window is the range of usable ink pressure that the printer can be set to, before print quality becomes unacceptable. The printer should operate at approximately 2900mbar (4000mbar for Pinpoint) with a message that uses all available lines. (1) Take a print sample by sweeping a piece of card under the printhead whilst triggering the product detector (simulating a product).

Page 226: Bench Mounting Stand
OPTIONS BENCH MOUNTING STAND A bench mounting stand or stationary stand (see page 10--15) must be fitted to the printer if there is no suitable surface to which printer can be bolted. The bench mounting stand comprises two 310mm long bars which fit to the underside of the printer.
Page 227: Stationary Stand
OPTIONS STATIONARY STAND A stationary stand or bench mounting stand (see page 10--14) must be fitted to the printer if there is no suitable surface to which printer can be bolted. This stand provides a secure support for the printer, placing it at a convenient height for the operator and making provision for a storage cabinet below.
Page 228: Storage Cabinet
OPTIONS STORAGE CABINET This cabinet provides secure storage for the fluids, cleaning materials, protective clothing, manuals, etc. It is fitted onto the stationary stand below the printer, and secured by two bolts to the uprights. The cabinet is made of stainless steel with a finish similar to the printer and the door has two catches like those on the printer ink compartment door.

Page 234 OPTIONS PHOTOCELL AND REFLECTOR ASSEMBLY This detector consists of a photocell and a reflector, which must be fitted on opposite sides of the product line. The reflector is adjusted so that a light beam from the detector, directed across the line, is reflected back into a photocell in the detector.
Page 235: Photocell Assembly Proximity
OPTIONS PHOTOCELL ASSEMBLY PROXIMITY This detector is fitted on the side of the product line and set up so that a light beam from the detector is reflected back by the product itself. The detector senses the reflected beam and printing starts when reflection either begins or ends.
Page 236: Inductive Sensor
The distances between the switch and the product vary depending upon the material from which the product is made and the application. Domino can provide further information and advice. Connection details are given in the diagram.
Page 237: Photocell Assembly Fibre Optic
OPTIONS PHOTOCELL ASSEMBLY FIBRE OPTIC This detector is fitted on the side of the product line and can be used where space is limited. It produces a light beam across the product line, when the product passes through the beam it causes it to be reflected back into the photocell giving a printgo signal to the printer.
