Positive Air Filter
Draining Procedure
Inspect the printer cabinet at the beginning of every shift. Check
the ink tank and other fluid components for fluid leaks, Use an
adjustable wrench to tighten the fitting, when finding a leak.
It is important to remember that leaks may cause other problems
than those at the source of the leak. Refer to the diagrams in
Chapter 3, Equipment Description, to track the paths of fluids and
air throughout the system, and ensure that potential problems are
corrected immediately.
WARNING: Do not overtighten a fitting. This will crush the fitting
and the tubing.
Positive air system is been applied to inkjet printer, to prevent the
nozzle from dust in dusty or humid environment. When using for
a long period, oil, water, or other wastes will accumulate in the
positive air filter. Check the air filter or drain the waste air before
everyday work, to keep the air clean.
This procedure describes how to drain the positive air filter and
ink trap. Oil, water, and excess particles accumulate in the
positive air filter and the ink trap. Drain each component every
day before turning the printer On.
WARNING: Before starting this procedure, make certain that AC
power to the printer is OFF, and the AC power and compressed air
supply to the printer are disconnected (unplugged). Failure to
follow this warning may result in personal injury.
1. Open the main printer door and locate the positive air filter on
the rear of the fluid pan. (Refer to Figure 6-7.)Locate the drain
valve on the bottom of the positive air filter. Place paper
towels underneath the drain valve. Press the drain valve to
release the accumulated liquid and particles.
2. Replace the positive air filter if required, otherwise check the
quality of the shop air entering the system. Accumulation at
the positive air filter may due to bad filters at the source air.
