4.3.17 Draining the Ink
0012-6385
There are two methods of removing the ink, using a manual method or automatic method.
When the ink is drained, the ink inside the ink passage totaling about228g(about38g x 6colors) is drained as
waste ink.
To prevent ink leaks, be sure to always remove the ink inside the ink passage when disassembling or
transporting the parts of the ink passage section.
1. Automatic ink drainage
Automatic ink drainage is performed by going to the Main Menu and selecting "Maintenance" > "Move Printer".
It takes about 4 minutes for automatic ink drainage to be performed.
Perform automatic ink drainage again if a power outage or other cause shuts off the power during the operation
for automatic ink drainage.
2. Manual ink drainage
A syringe or other implement is used to remove the ink inside the ink passages one color at a time in the event
of a printer electrical failure, firmware error, or malfunction in supplying power to the printer.
Manual Ink Drainage Procedure
