Consequences
Check / Cause / Remedy / Solution
87
D
High Voltage
insulation failure
The printer detected an
insulation fault on the EHV
lines during operation
(current leak of more than
10 µA).
Consequences:
EHV cut.
Printing is disabled.
1- Cleanliness of deflection plates
Cleaning with soapy water and letting dry may solve
the problem.
2- Cleanliness inside head
Open the rear cover.
Clean away any traces of ink or moisture and dry.
Locate and eliminate the source of the leak.
3- EHV block
4- IM
88
D
Jet speed
measurement
timeout
The printer cannot calculate
the jet speed at start-up and
during operation.
Consequences:
Printing is
disabled.
1- Cleaning
-
Clean the head and the cover
-
Clean the modulation assembly (Jet tip, SV
intro., Stab. check)
2- Ink quality
-
Dust, moisture, use-by date (rinse, refill with
new ink)
3- Electronics
-
Break-off point (piezo, piezo board, IM, CPU)
-
Charge signal (IM, CPU)
Detection signal (ADP board, IM, CPU, , bonding
between cover and CPU)

A
Head temperature
out of range
The temperature measured
inside the head is outside the
limits of 0-45°C (32-113°F).
Consequences:
Adverse
effects on the electronics and
behavior of the ink.
1- Room temperature
2- Temperature sensor on ADP board
3- CPU board
91
D
Temp. inside
console > 60°C-
140°F
The temperature measured
inside the console is above
60°C (140°F). Running the
printer under these
conditions may damage its
components.
Consequences:
The IMM
stops. Printing is disabled.
1- Room temperature too high
2- Poor console ventilation
-
IP54 air intake filter clogged
-
Flow of compressed air flow on IP65 too low or
too warm
3- Temperature sensor on CPU board
