Review of the Roland LG-640

[Goatshaver]

Yikes. This and the lack of knowledge of the machine from the salesman is what made me decide against getting a Roland UV machine. Hope for y'all sake they fix this issue soon.

Small update on our new machine - 4th day of having a tech here, Roland's tech came out to swap out the head for a new one. Exact same result as the previous head with orange missing completely and the same missing nozzles on the red channel.

Roland tech also realised that the machine has been setup incorrectly - laying white on top of CMYK rather than the other way around. Another layer of things to fix and correct...

Surely the print order is set in the rip? We regularly print white on top of cmyk by choice.

Heads are staggered, so the order that the heads are physically in determines whether you can print white over/under without the need to pullback the media.

Having them in the wrong order means halving the print speed as it has to feed the media back for the second pass.

Ah ok. Interesting. We are running an LG-640 with a single 8 color head.

Did you check your ink expiry dates for red and orange? We lost red almost completely (only a few nozzles remaining) then switched to new ink, renewed ink and the head came back to perfect condition.

Are you sure? The LG series has 2 staggered heads.

Sorry meant to type MG-640

 

[BVG]

Ahhh yeah that makes sense haha.
MG is running the same platform as the old VS solvent series (including Epson head) whereas the LG is Ricoh heads from memory.

It does feel like a museum piece compared to our other machines. We considered the LG but I’ve learnt to never buy the first version of anything. Our old SG and VS printers were workhorses.

After having issues with red and orange inks, then later on with magenta, our lg got parked for about 2 months waiting for ink issues to be resolved. I ended up switching from 8 color to 4 color dual cmyk. Machine is much faster with less waste, but black still isn’t black enough.

Ink is also still on back order for a while now, maybe 2 months for me.

Roland needs to fix these issues or they will lose dedicated customers.

We haven't used our LG-640 since december. Never put the machine into production. It's in the hands of the lawyers. (Dealer doesn't even reply to emails (send to 5 people)).
