A Ink concentration
out of
specifications During printing the working
pressure required for proper
jet speed is outside the P =
f(T) curve.
This alarm may be caused by
too much or too little make
up in the ink.
Consequences: Poor print
quality.
1- Check the following parameters:
Ink
Head height difference
Ink and make up reference and use-by date.
2- Check the reference pressure (PRef) against
the actual pressure measured in the
accumulator (PAcc).
If PAcc < PRef: There is too much make up in the
ink.
Avoid stopping and starting the printer
repeatedly.
Let the printer adjust the concentration itself.
If PRef < PAcc: There is too little make up in the
ink.
Check the make up cartridge
Let the printer adjust the concentration itself.
3- Auto-calibration

D
Ambient pressure
measurement
failed The atmospheric pressure is
measured via solenoid valve
4 and the condenser each
time the printer is started. If,
after 3 attempts, the value
measured is not 0 bar ±
300 mb, the pressure sensor
is defective.
Consequences: The IC60
stops and printing is
disabled.
1- Test solenoid valve 4
2- Check the condenser vent
3- IC60
72
D Motor
synchronisation
incorrect The printer does not detect
sufficient difference in
pressure between the pump
top dead center and the
bottom dead center at start-
up and during operation.
Consequences: The IC60
stops and printing is
disabled.
1- Test solenoid valves 0, 1, 2, 3, 4, 5, 6 and 10.
2- Make sure there is no ink in the air pump.
(Kapsto 6)
3- Make sure the motor is running.
4- IC60.
