■ Ink filters
The primary filter is inside the accumulator on the ink circuit. It cannot be changed.
To reach the 14 µ grid filter on the SV 11 inlet, remove the solenoid valve's support bell. Removing
the filter is not recommended (risk of ink circuit contamination).
■ Make up filter
In order to filter the make up which is directly aspirated out of the cartridge during the head rinsing, a
5 µ filter screen is located between the make up tip holder and the ink circuit. To reach the filter
screen, remove the tip holder.
■ Calibrated restrictors
The hydraulic system has three restrictors located in the print head.
The first is in the hose exiting the recovery gutter solenoid valve. This restrictor optimizes the
recovery signal. It is able to be changed if necessary.
WARNING: The restrictors have a diameter of:
- 0.7 mm for 1.1G, 1.2G and 1.2M printers
- 0.5 mm for 1.1M printers
A second restriction measuring 0.6 mm is built in to the gutter in order to reduce the air intake and
thereby optimize make up consumption. The entire gutter is interchangeable.
The third restriction is located at the refreshment exit of the modulation chassis. Its diameter depends
on the modulation assembly type. The modulation chassis is interchangeable.
