1. Ink Pressure Gauge
The ink pressure gauge indicates the amount of air pressure (in
psi and bar) applied to the ink supply cylinder. This pressure is
commonly referred to as "ink pressure". The ink pressure is
controlled by adjusting the ink pressure regulator (refer to page
3-10).
2. Ink Pressure Regulator
The ink pressure regulator is used to adjust the ink pressure, and
accordingly to change the speed of the ink steam. According to
the style of ink and the measure of print head, ink pressure is
usually set at 2.8- 3.5 bar(40- 50 psi).
WARNING: Do not adjust the ink pressure regulator unless
you are performing the "Viscosity Calibrate"
procedure. (Refer to page 6-26)
