Maintenance system
- purging manifold, vacuum knife pistons,
and maintenance bath lifting pistons
The required pressure for the compressed air is
6 bars
with a
minimum flow rate of 120 liters/min (4.3 cfm). The compressed air
inlet is located inside the machine in the rear left corner.

Vacuum System
The main functions of the vacuum system are:
•
Holding the substrate on the printing table
- a unique vacuum
system, especially designed to apply vacuum to the vacuum
printing table along the X-axis (see
Printing Table
on page 15).
•
Cleaning the print heads -
as part of the maintenance system, a
vacuum knife is used to clean the print heads (see
Vacuum
Knife
on page 37).
