Assembly and function 72800115 Markoprint X4JET
In the MX Compact / Compact/Vario model, the print head and the ink system form a
single unit. A constant difference in level between the print head and the ink system is
thus ensured. For design reasons, the print head of the Compact / Compact/Vario
model can only print from the side.
In the event of installation on an inclined conveyor or material movement from top to
bottom the ink system must be installed horizontally. The head can be rotated in the
direction of travel. MX 100 Compact system is not suitable here because the head
cannot be rotated independently of the ink system.
In the Top model, the print head is connected with its own ink system via a special
flexible hose containing the ink line and the control cable. The ink system comprises a
reservoir to which the ink cartridge is attached. A pump is also installed. This pump is
used exclusively for purging air and any contamination from the head. The ink is
supplied to the print head solely through the suction effect of the ink being used. Reliable
ink supply can only be ensured if the system is fully vented. It is important that the ink
system is installed at the same height as the print head.
Note: The lower edge of the nozzle plate (by an installation from the side: lower edge of
the print image/bottom nozzle) must be set 55 mm higher than the lower edge of the ink
reservoir (+-5mm space). If the ink system is higher than the print head, the ink will leak
from the head; if the print head is installed too high, the surface tension of the ink at the
nozzle plate will be disturbed, causing air to enter.
