Problem with DX5

[Dr_Andriy]

Hello everyone.
There is a problem with the DX5 head. I recently serviced a Mimaki JV33 owl printer and removed the head for cleaning. Unfortunately, when I collected everything, one channel stopped working. Tried changing dampers, but nothing helps. Is it a problem in the head, or could it be something else? Thank you.

Most probably it's the cable.

I’m checked cable. It is not in perfect condition, but it works. I have already ordered a new cable, I will try to replace it. But I don't think that the problem is in him.

It could possible be the pump as well.

 

[Dr_Andriy]

The pump and cap is in good condition. I replaced the ink tubes and did Fill up.

Do you see ink in the lines?

 

[Dr_Andriy]

Yes, the ink is in the line. ink is pumped through the head.

That's a pretty common issue I've seen with the older JV33 and CJV30 models. I would change the cap top slider or just the whole station entirely. The slider is usually the culprit though. The pegs that slide back and forth wear out and cause the cap top not line up correctly and it always makes that left magenta disappear first.

I don't think this is the problem. The cap is new, everything is sealed, the pump fill all channels very well. After filling with ink, all lines started printing normal except magenta.
