Deliver the ink into
the Sub Tank by
executing the
[SUPPLY] function
of Supply Pump.
If the Sub Tank doesn't get full after rotating the Supply Pump
a certain times, the machine recognizes the ink cartridge is
empty, resulting in an ink empty detection.
If a certain amount of air comes inside the Supply Pump, the
Supply Pump can't deliver the ink to the Sub Tank and causes
this phenomenon. It is necessary to remove ink from the ink
line using a syringe. Refer to [5-2-6 HOW TO REMOVE AIR IN
SUPPLY PUMP OR INK TUBE BETWEEN SUPPLY PUMP
AND SUB TANK].

If the Sub Tank doesn't get full after rotating the Supply Pump
a certain times, the machine recognizes the ink cartridge is
empty, resulting in an empty detection.
If the amount of ink inside the Sub Tank is less than expected,
(if the ink inside the Sub Tank is delivered back to the ink
cartridge with a service menu function or by opening the
Supply Pump.) this phenomenon takes place. It can be solved
by increasing the ink inside the Sub Tank by executing
[SUPPLY] of the corresponding Supply Pump in the service
menu.
