Mutoh vj1614 magenta print problems

[signsuperstore_AL]

I do a head clean and the nozzle check works perfectly then it stops printing magenta after about 2 inches of print. Do another head clean, nozzle check is perfect.. 2 inches of printing no more magenta.
Its a new cartridge and makes no difference. Was printing fine then sat for about 4 hours and then this started.
Any ideas?

update: It was printing only a small piece and the Cr was set to "data" instead of "Machine". I f I make it go the full width it prints fiune.. almost like it is going too fast to feed the magenta..
Definitely a new problem!!

WIthout knowing more, it almost sounds like a damper issue - when is the last time those have been changed? Over time dampers can clog with sediment/pigment particles from the ink. I would also check to make sure there are no air bubbles in your magenta lines that might indicate an air leak somewhere....

I ordered some dampers.. Will let you know. Thank you very much.

You're very welcome - glad it wasn't anything more serious!

My 4the printhead is broken. Always the cyan part of the head is bat. I use a bulksystem whit UMS ink (original). We replace the heads after cleaning en replace all the materials thats neccesery. Mutoh says "Its the oxidation of the cyaan because thats not a closed system. Now, after repeat the hole procedure, we use cartridges. We have the same problem, spray in the cyan.
Is there someone whit the same problem?

Try to check if there is air in the magenta ink tube
