can anyone help with printing head please?

Posted by bladewar on 25 October 2009 at 23:33

Hello,

I have a printing problem with my CJ-500. One of the heads will not print. Technical service at Roland told me that this motherboard is HS.
I seek to have a little more information. And perhaps, or find a motherboard to replace mine.

Thanks for help

You can get the boards from here. I have used them for parts and the service was excellent.

Thanks,

1920 Euros 😮 …. whaaaaaa !!!

The problem is that I am not sure whether it’s a motherboard problem.

The machine cuts, and prints only a single print head. Printheads are new, and I did a test by inverting the cross cables, the other headers works .. may be the small map of heads and not the motherboard. How do I know??

dont know anything about ur machine, not a thing…
but quite often on mimaki’s and some rolands, there is a board above the print head and this has minutare surface mounted fuses on it and they blow, they can blow if you put the ribbon cable in the wrong way round.

just a thought.

Below the motherboard there is a head carriage board which may be the board Roland were referring to and Dave mentioned.

Hello,

Bad news, I changed the "carriage board and it works not. We must change the motherboard.
I search for an opportunity motherboard.

Tell us a little more on what had gone on. Did you just change a print head and then it quit printing? Was it printing well and then gradually quit or all of a sudden stopped?

Is this converted to solvent or still water based inks?

I had a head that was missing a lot of nozzles and took it out and tried to clean it and when I put it back in nothing fired, not a spec. Put in the new head and all was good.

The machine is still ink water. This type of machine can not be eco solvent.
I changed the 2 heads, but I disconnected one of the heads who forgot to ‘turn off the power.
This is the motherboard that has taken a hit. But recently I found a repairer in France. It will attempt to repair my motherboard without changing it completely.

Ok. Sounds like you know what your problem is. Hope you get up and running again.

Just for your info as well, you can convert the CJ 500 units to solvent and if you are a handy person you can do it your self. The CJ has the same main parts that the SC 500 does. You do need to change a few things to solvent resistant parts but the heads are identical. You will have more up keep with it being solvent but they sure can print nice and you can have a full blown ecosol printer for about $1000 extra. I made my own heat plates with in floor heat cable and use a dimmer switch to control the temp. There are a lot of CJ 500 units converted. Also a lot of info on this site about it.

Not sure if you are still following your post here but a thought crossed my mind.

When you changed heads did you re enter the new head rank for each head? I would assume you would have, as you said one head worked.

I know you said you think it’s the board but just in case you did forget to change the head rank, that is an easy fix.
