1.3.8 Ink Suction and Discharge Control
Outline of Control
1.The ink suction and discharge mechanism is driven by roller pumps (ink suction pumps).
2.The amount of ink discharged to the waste ink tank is counted by the firmware, and warnings are issued depending
on the level. They are displayed in sequences involving ink suction and discharge, or locally.
3.The printer is equipped with an automatic cleaning mechanism (pump tube cleaning) to prevent ink solidification in
the waste ink tube connecting the inside of the cap to the waste ink tank.
4.Cleaning is performed by drawing washing liquid from the washing liquid cartridge to the cap using the siphon
principle. It is performed periodically when power is turned on/off.
System configuration
The system configuration of the ink suction and discharge mechanism is as shown below.
Outline flow
In initial filling for the 4-color ink set, to eject air completely from the ink paths, the suction is divided
into 2 stages, (
) filling up to the coupler, and () filling up to the nozzle. Each uses the sub cartridge
and control cartridge.
