Actions in the ink path that prepare the printer in a state of circulation for printing on the media
1) Print signal received.
2) Maintenance unit stored on the paper ejection side of the printer, belt platen raised to the position for printing.
3) When the home position is detected by the bellows pump sensors, the pressurized ink tank air valve opens and the negative pressure ink tank air
valve closes.
4) The circulation pump is activated while the bellows elevation lever is lowered to the lower limit sensor position and the negative pressure ink tank
is negatively pressurized to a specific level by means of the spindle.
5) Ink is now in circulation.
During circulation:
When ink is present in the
pressurized ink tank
During circulation:
When no ink is present in
the pressurized ink tank
Transition to idle (standby)
state
Action after printing is finished (transition to standby mode)
This action occurs after printing. The sequence is the same when the printer is turned OFF.
1) Printing action is completed, and if no print signal is received in a specific period (by default, 0 sec.), the circulation pump stops, the pressurized
ink tank air valve closes, and the negative pressure ink tank air valve opens.
2) The elevation lever of the pressure adjusting bellows raised to the home position.
3) The printer is now in standby mode.

Standby
Sleep
Transition to sleep
There is no change along the ink path.
1) After a specific period in standby, the maintenance unit emerges under the heads.
2) The elevation lever of the pressure adjusting bellows is lowered to the lower limit sensor position.
3) The printer is now in sleep mode.
