Do you have that covering film on the bottom side of the alu board or did you remove it. That film usually helps the grit rollers to move that board better. Or you can try to cut stripes from your printing vinyl and put them on the bottom side of the board at the place, where the metal grit...

HA! I use the EFI Fiery XF and as I said, I print in 720x720 dpi Mode Sharp (1 dot). I suppose this is the mode that Roland recommends to fix the vertical banding problem. But I have to say to you: even this mode DOES NOT HELP. I can show you lots of photos I made (just taken pictures of my...

Two months ago we also had problem with the density of yellow ink. Simply, all print outs were kind of blue-casted. Technician guy came to us and changed a filter for yellow - it was clogged by dirtyness (or maybe just small particles from the solidified ink). Since then yellow works without...

Hmmm, I saw f.e. the print output from EFI H1625 LED (so it has the LED lamps too) and it was perfect, with no banding. We use now the EcoUV v4 inks, before we had the EcoUV v2. Both of them produce the vertical banding. :(

Hi, thanks for you comments. I have to say, that unfortunately there's no change with our LEJ-640. Two weeks ago I was discussing with our vendor. Then they (as they told me) talked with some technician guy from Roland and they said to me, that there's one printing mode with fixed drop size (is...

Yes, that's true. So no pinch rollers trails. As I also said, when I changed the printing parameters (lower scan-speed), those vertical stripes were there again, but thinner and closer to each other.

Sorry, but what you said about the pinch rollers is a big nonsense! You probably never saw the LEJ-640 machine. First: pinch rollers are not touching the printed inks, they go AFTER the printed inks (they are positioned behind the printhead, not before). Second: during my tests I tried different...

No, I speak about the VERTICAL banding, not the horizontal, which is of course typical for the hi-speed and lo-res printing. I use the 720x720 dpi, 720x1080 and 720x1440 dpi so really slow speeds, and vertical banding is always there - most visible in bark solid color areas and almost invisible...

Hi there. We have the same problem with the vertical banding and I know atleast two more owners of the LEJ-640 here in my city, who struggle with the vertical stripes aswell. It's most visible on the solid dark color areas, especially rich black is the worst... we printed on the rigid PVC...
