Clicking the figure number under the video mark allows you to view the movie showing the procedure.
There are two methods of removing the ink, a manual method and an automatic method.
When the ink is drained, the ink inside the ink passage totaling approximately 228 g (approximately 38 g x 6 colors) is drained as waste ink.
To prevent ink from leaking, be sure to remove the ink inside the ink passage when disassembling or transporting the parts of the ink passage section.
1. Automatic ink drainage
To perform automatic ink drainage, go to the main menu and select "Maintenance" > "Move Printer". It takes about 4 minutes for automatic ink drainage
to be completed.
If a power outage or other cause shuts off the power during the operation for automatic ink drainage, perform automatic ink drainage again.
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 failure in supplying power to the printer.
a) Preparation
Prepare the following items before starting the manual ink drainage procedure.
1) Syringe having approx. 50-ml capacity (CK-0541-000) with connecting tube (QA2-6161-000)
If possible, try to use separate syringes for each color.
If the syringes are severely stained or if the tubes are attached to different-color needles, flush and wash the tubes (syringes) with water and allow them to
fully dry to prevent mixing of ink colors.
b) Overview of manual ink drainage
Perform manual ink drainage using the three steps described below.
Step 1: Simultaneously flow ink from all ink tubes (for six colors) to the ink absorber in the ink supply mount .
Step 2: Drain the ink in the ink tank to the cartridge one color at a time.
Step 3: Repeat step 2 for the remaining five colors.
