To cut a long story short our cjv150 was dripping ink onto the media last week. We replaced the dampers and capot and the problem was resolved. This week we now have cross contamination in the yellow channel. This is present as soon as we turn the machine on after it has been left overnight and...

Hello I have a problem with the printer Roland RE-640. Pleas help me!!

Hello, everyone! As using JV33-160A, there are many problems. The big issue was solved today with helpful advise of the member "Solventinkjet". And the other issue is the banding and color change. I printed on PET Film with aqueous pigment. But there are too many banding problems. After...

Hello, My Mimaki CJV30-60 was left sitting idle for a whole year. The nozzles were working perfectly before then. So I recently changed the dampers, tubes and capping station. I also gave the printhead an overnight soak. I went into options and selected Ink Fill Up. Still nothing was coming...

My SP300 started acting up lately. While printing 4" CMYK test squares, I noticed that the cyan square had light coverage and minor overspray and the black square had overspray. I shook each ink cartridge and discovered that the cyan was empty. After replacing the cyan ink cartridge (OEM inks...

Hi there, Just yesterday I changed all 8 dampers on my Mimaki CJV30-100 with cheap Chinese dampers (complete with O-ring and screwcap). I bought the machine second hand and have the machine for 1,5 year now, so probably about time. Hoped it would solve some of the banding I can't seem to get...

On a Mutoh ValueJet 1614E machine the nozzle check for one side of black ink was not perfect. I had a clogged nozzle from some time and I tried to unclog it. I pulled some cleaning liquid through the nozzles. Gentle, without pushing hard until all the jets were clean and parallel. I mounted the...

In the service manual it says to fill the new dampers with cleaning solution prior to installing. Also says to do a head wash to empty the ink lines/dampers prior to removal. On the 1604 I did not do this and wondered how different the 1614 damper procedure is. Any tips on replacing these would...

Hi, My VS-640 has light cyan ink dripping from the head. It is a consistent drip. Ive replaced the cap top and wipers and did manual cleaning to confirm there is nothing causing the ink to drop like a wick draws fluid. Im thinking it is the damper, but would only 1/2 of a damper go? Ive...

I'm fairly new to the forum and the signage world (my background is mostly identity design). Attached is a photo that shows to different print files. both cmyk. The print on the left is a solid vector color. The print on the right is taken from an image. Both came from Illustrator files. Any...

What is the proper procedure for installing a JV5 damper. Can you damage a head by drawing ink through a disconnected damper?

"Having done a print test before getting started, I noticed the Magenta had bled into the yellow side. Once I opened the printer and examined the damper, I could see it was 1/2 mixed (contaminated). It was a situation I would have to attempt myself as the tech guy is a 10 hr. round trip. So I...

I have had problems for 2 years with the black output on my Roland SC545-EX. Here's the scenario: I start printing a banner with full bleed black, it starts fine but after a couple of feet a slight over spray starts, it eventually gets worse, then the print starts to go bad, I can see that not...
