Good morning,
Can you help me, I have a LEF-300 so I don't use it much.
And I encounter a problem, sometimes certain colors disappear completely and they come back as if by miracle after several weeks.
It's like the ink isn't getting to the print head
I don't know what to do, I'm capable but since I don't know, I don't want to do anything stupid.
Can you advise me and tell me where to go, what I should check first, a tip for testing, what I should replace.
Thank you in advance for your answer.
