Consequences
Check / Cause / Remedy / Solution
77
A
Pump
performance
incorrect
The ink pump compression
ratio is insufficient.
Consequences:
No direct
consequences. The printer
remains ready.
1- Test solenoid valves 0, 1, 2, 3 and 4
2- IMM
78
D
Printer empty. No
more ink available
The accumulator, buffer tank
and ink cartridge are empty
during printing.
Consequences:
The jets
stop.
1- This fault follows alarms 50 and 52
The printer immediately stops
2- IMM
3- CPU
79
D
Condenser
overflow
This fault appears during
operation if liquid remains in
the condenser after 10
consecutive pumping cycles.
Consequences:
The IMM stops and printing
is disabled.
Partially drain the ink in the printer and measure
the amount collected.
Reminder: This will drain the buffer tank.
1- If ink collected < 200 cc
The overflow is caused by a crack in the ink pump
diaphragm. Ink has flowed to the condenser via the
air pump (ink overflow). Replace the IMM.
2- If ink collected > 200 cc
The overflow is caused by too much additive in the
ink. Restart the printer. Check the auto-calibration.

Faulty drop charge check.
Consequence:
The printer
cannot print.
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)
-
Auto-calibration
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)
