jv33-160 test draw

[mathieu69590]

hello everyone, I have a jv33 160 mimaki, I have a problem with the colors, when I do a test draw, red and blue are often clogged.
when i suck the ink with a needle from the printhead, you have to press the tap behind the cartridge to let the ink flow. i have to open them all at the same time? or one by one and repeat the operation ???
because under the print head there are 4 zones
zone 1: red and blue?
zone 2: yellow and black?
zone 3: black and yellow?
zone 4: blue and red?

sorry for my english because i'm french

If you pull from the bottom of the cap you should open all the ink valves.
When was the last time you replaced cap and dampers?
Also, it's highly possible that you just need to adjust the cap.

For open the vavle you can take automatic ?

You should be able to open the valves under #test- cartridge valve
