Initial Setup
See Figure 1.
Before putting the Ink-Dot system into service for the
first time you must first flush the system with a
compatible solvent and then fill it with ink.
Perform these steps before putting the Ink-Dot
hydraulic system into service for the first time.
1. Close the air shut off valve (21).
2. Set the air pressure regulator (20) to 0 bar/psi.
Pull the relief valve lanyard (19) to relieve system
air pressure.
3. Make sure that the drain valve (17) is closed.
4. See Figure 2. Unscrew the cap (2) from the
reservoir (1).
5. Fill the reservoir with a compatible solvent. Install
the cap onto the reservoir.
6. See Figure 1. Open the air shut-off valve (21).
7. Set the air pressure regulator (20) to 0.4–0.7 bar
(5–10 psi).
8. Place a waste container under the bleeder
valve (15). Open the bleeder valve and allow the
solvent to flow through the system. This will also
purge any air from the system. Close the bleeder
valve.
9. Manually trigger the Ink-Dot gun (10) to purge
contaminants from the gun.
10. Close the air shut-off valve (21).
11. Pull up on the relief valve lanyard (19) to relieve
system air pressure.
12. Place a waste container under the drain
valve (17). Open the drain valve to drain the
solvent from the reservoir.
13. Close the drain valve.
14. Fill the reservoir with ink. Refer to Filling the
Reservoir.
Filling the Reservoir
See Figure 1. Follow these steps to fill the reservoir
with ink after initial startup or flushing the system.
1. Repeat steps 1–8 of Initial Startup using ink
instead of the compatible solvent.
2. Manually trigger the Ink-Dot gun (10) to purge any
remaining solvents from the gun.
3. Adjust the dot size. Refer to Dot Size
Adjustment.

Operation
See Figure 1.
NOTE: The break-in period for the valve seat is the
first 10-24 hours of operation. If the dot size
increases, refer to Dot Size Adjustment.
Startup
1. Open the air shut-off valve (21).
2. Set the air pressure regulator (20) to
0.4-0.7 bar (5-10 psi).
3. Turn on the Ink-Dot controller power switch (9).
4. Turn on the driver power switch (7).
5. Set the RUN/OFF/TEST switch (6) to RUN.
6. If desired, adjust the dot size. Refer to Dot Size
Adjustment
Changing Materials
1. Close the air shut-off valve (21)
2. Set the air pressure regulator (20) to 0 bar/psi.
Pull the relief valve (19) lanyard to relieve system
air pressure.
3. Place a waste container under the drain valve
(17) and open the drain valve. Allow the ink to
drain from the reservoir (18) into the container.
When the ink has drained from the reservoir close
the drain valve.
4. See Figure 2. Unscrew the cap from the
reservoir (1) and fill with a 1/2quart of compatible
solvent. Install the cap (2).
5. Perform a solvent flush. Refer to Initial Startup
and perform steps 6–12.
6. Fill the rervoir with ink. Refer to Filling the
Reservoir.
Shutdown
CAUTION: Failure to turn off the
RUN/OFF/TEST switch can cause damage
to the gun nozzle and ball and seat
assembly.
See Figure 1.
1. Set the RUN/OFF/TEST switch (6) to OFF.
2. Turn off the driver power switch (7).
3. Turn off the controller power switch (9).
4. Turn off the air supply link to the reservoir by
closing the air shut-off valve (21).
5. Set the air pressure regulator (20) to 0 bar/psi.
Pull on the relief valve (19) lanyard to relive
system air pressure.
Dot Size Adjustment
See Figure 1. Follow these steps to adjust the dot
size from the Ink-Dot electric spray gun.
1. Set the RUN/OFF/TEST switch (6) in the Ink-Dot
control unit to OFF.
2. Set the air pressure regulator (20) to
0.5 bar (7 psi) at the ink reservoir.
3. Loosen the locknut (13).
4. Carefully screw in the armature sleeve (12) until it
stops or bottoms out.
5. Unscrew the armature sleeve approximately 1/12
of a turn or 30_.
6. Hold a piece of paper by the bottom of the can
and in line with the nozzle (11).
7. Set the RUN/OFF/TEST switch (6) in the
Ink-Dot control unit to TEST. Adjust the
armature sleeve (12) until the dot is the desired
size, typically 2–3 mm.
NOTE: Do not hold the armature sleeve screw with
the screwdriver while you are tightening the locknut.
8. Use a 1/2-in. wrench to tighten the locknut.
NOTE: The dot size will become slightly larger when
tightening the locknut.
9. If desired, change the fluid pressure to make fine
adjustments to the dot size:
SIncrease the pressure for a larger dot.
SDecrease the pressure for a smaller dot.
NOTE: Refer to the Ink-Dot Series II Driver manual
to make additional adjustments to the dot size using
the dip switches.

12. Adjust the dot size. Refer to Adjusting the Dot
Size.
Maintenance
Table 2 provides maintenance procedures for the
Ink-Dot system.
Table 2 Maintenance Schedule
Frequency Task
Daily Wipe or brush the nozzle once per shift with a solvent that is compatible with the ink.
A nozzle brush is included with the gun.
Weekly 1. Refer to the Ink-Dot gun manual to check the Ink-Dot gun mounting angle.
2. Check the distance between the
Sproximity sensor and can conveyor
SInk-Dot gun and can conveyor
Sgun nozzle and proximity sensor
3. Make sure that the proximity sensor is perpendicular to the side of the can.
Periodically Check the ink level in the reservoir.
3–6 months Flush the system with a compatible solvent and replace the inline filter element.
9–12 months Replace the ball and seat, seals, O-rings and inline filter element in the gun.
