Pneumatic Requirements The supply of compressed air to the HP Scitex FB7600 printer may be by way of a central air supply system, or with the use of a dedicated air compressor. In either situation, a wall-mounted air outlet will be required. This should have a quick-coupler fitting and be located near the FB7600 printer. Air Compressor Air compressor requirements: Operating pressure: 6 - 8 bars (88.2 - 117.6 psi) Flow rate: Minimum of 1200 liters/min (43 CFM) Air cleanliness: The air should be filtered to 5 microns before reaching the FB7600 printer. Reservoir size: 400 lit. Air Dryer An air dryer is required to ensure that the supplied air to the system is moisture free. Air dryer requirements: Operating pressure: 6 - 8 bars (88.2 - 117.6 psi) Flow rate: Minimum of 1200 liter/min (43 CFM) at 6 - 8 bars (88.2 -117.6psi) Dew point: 2°C (35.6°F) Environmental Requirements Lighting Whenever the FB7600 printer is in operation, the print production area should be well illuminated to provide the operator with optimal conditions for checking print production (color, alignment, etc.). If there is insufficient natural light, the installation of supplementary artificial lighting will be required. Caution To avoid curing of the ink while the bridge is in vertical position (during maintenance), the following guidelines are recommended: • Do not position a light source directly above the printing bridge. If there is one directly above the printer, it should be turned off while the bridge is in vertical position for more than a few seconds. • The power density of a light source above the bridge should not exceed 3mW/cm2. • Sunlight is a real risk in case there is an open window that allows direct sunlight into the room and towards the exposed bridge. Make sure that such windows are shut. In general, if the bridge is left in vertical position for more than a few moments, it should be covered. 32 HP Scitex Industrial Presses Essential Health and Safety Instructions

HP Scitex Industrial Presses Essential Health and Safety Instructions
Pneumatic Requirements
The supply of compressed air to the HP Scitex FB7600 printer may be by way
of a central air supply system, or with the use of a dedicated air compressor. In
either situation, a wall-mounted air outlet will be required. This should have a
quick-coupler fitting and be located near the FB7600 printer.
Air Compressor
Air compressor requirements:
Operating pressure:
6 - 8 bars (88.2 - 117.6 psi)
Flow rate:
Minimum of 1200 liters/min (43 CFM)
Air cleanliness:
The air should be filtered to 5 microns before reaching the
FB7600 printer.
Reservoir size:
400 lit.
Air Dryer
An air dryer is required to ensure that the supplied air to the system is
moisture free.
Air dryer requirements:
Operating pressure:
6 - 8 bars (88.2 - 117.6 psi)
Flow rate:
Minimum of 1200 liter/min (43 CFM) at 6 - 8 bars (88.2 -117.6psi)
Dew point:
2°C (35.6°F)
Environmental Requirements
Lighting
Whenever the FB7600 printer is in operation, the print production area should
be well illuminated to provide the operator with optimal conditions for
checking print production (color, alignment, etc.).
If there is insufficient natural light, the installation of supplementary artificial
lighting will be required.
Caution
To avoid curing of the ink while the bridge is in vertical position (during maintenance),
the following guidelines are recommended:
•
Do not position a light source directly above the printing bridge. If there is one
directly above the printer, it should be turned off while the bridge is in vertical
position for more than a few seconds.
•
The power density of a light source above the bridge should not exceed 3mW/cm

.
•
Sunlight is a real risk in case there is an open window that allows direct sunlight into
the room and towards the exposed bridge. Make sure that such windows are shut.
In general, if the bridge is left in vertical position for more than a few moments, it should
be covered.
