The photos are blurred...I can't see much...but it could be banding What temperatures do you have on heaters?

You can find the procedure here: Adjust The Print Head - Mutoh ValueJet VJ-1204 Quick Reference [Page 79] Also, check the vertical slant angle: MUTOH ValueJet Service Manual (Page 295 of 393) and it can be adjusted from the head adjusting cam: MUTOH ValueJet Service Manual (Page 293 of 393)

If it's a static like issue, you could try to lower the print head and see if that resolves the issue. But before taking the head height into consideration, you should make a test to see if all the colors have this problem or only one of them. To check this, make a test like in the attached...

This can happen when the printhead doesn't have the correct voltage and temperature (not getting enough voltage, low temperature of the printhead) or problem with the ink.

You can see them here:

It's where is less background colour and more white on that pass, letters like U,L,N or when the top of the letters are in the same line, like TER.

Then the inks should be the first suspect.

Make some rectangles wide as the vinyl width (in any graphics software): one filled with Cyan, one with Magenta, one with Yellow and one with Black (C0,M0,Y0,K100), export the graphics in CMYK mode, send them to print and see if this problem happens on all the colours or just one. Also, see if...

Nicely done! That must be it. Keep us posted.

In the jv400lx operation manual it's a little bit different. It says "Error 618 to 61b are errors related to the damper". But what you said is quite possible.

The siphon effect crossed my mind, but I didn't see it possible, since, as you also stated, there should be a solenoid valve somewhere (usually between the cartridge and the subtank). Probably, it empties all the ink from the subtank, and that could be much. I don't know what amount of ink you...

First of all, I should say that.... this should be done by a qualified technician. If it's not done right, it can cause more damage then the inital one (by not replacing all the defective components and by not finding the initial cause of faulty). Measuring electronic components in a circuit...

Hello Will, you should check the dampers.

A possible cause could be a dirty encoder strip.

Make sure you have the print head height set to Low. If it's on High, you can have this mist effect. As ams said, your print is quite grainy. What type of ink do you use and what color profiles? What temperatures do you have on the heaters?
