Spillage.......................

wow... I wonder what it is doing to everyones brain cells...

 

Most times its the captop filters that swell up and touch the underside of the heads and starts a siphon. Most times it would stay to one side or one head.

A drain line too deep into the drain bottle and if it touches the waste fluid it will siphon out.

Was it real hot in there over that time period? I had a hot week where it seemed the pressure in the carts expanded and forced some ink to siphon but drew back into the color beside and filled the damper and some of the line with the other color.

Also one almost empty cart can cause a draw backward and start the other lines to siphon out.

 

Had that happen here once with our JV3, didn't empty the tanks since it happened while we were in the office.

 

Captops have been known to swell, and cause contact with the printhead nozzle plate, This can cause a siphoning of the ink into the waste tank, and overflow it. It has been a fairly rare issue with the Roland printers (more common with the old Mutoh Falcon Outdoor).

Solution is to regularly replace your captops (2 on that machine) before problems occur. Roland recommends replacing these every 6-12 months, and they run $25 ea. They take only a few minutes to replace, and do not require a service visit.

Also, Roland does not recommend shutting off the machine, even over weekends. You're right that Roland Eco-Solvent Max is nasty when it contacts certain plastics etc...it is still comprised largely of solvents.

 

The Epson GS6000 inks are pretty nasty too. I received a broken cartridge and the ink dissolved the plastic housing.

 

You may be able to answer this. To Castek Resources

Both captops would have had to have the same thing happen at the same time in order for both heads to drain the ink on all 4 carts.... correct? Does that happen often for both to do it at the same time? Could one side (captop) effect the other captop. I was thinking they would be both separate and not effect the other. Just trying to think why both would go at the same time.

 

I can use cheap refill carts on my old CJ so no chip is required and no need to worry about that part of it. I am thinking of running the refill carts (even if using Roland's inks) and just drain the bags into the refill carts.

This would solve any pressure issue that ever could occur inside the bags as well as stopping the issue where, with an almost empty cart, it draws ink back into it's line due to the negative pressure.

You still have to watch the pads for swelling and touching the heads but with the refill carts having an air hole in the cart, they could never pressure up.

Can you use a refill cart and attach the chip from the carts you use and go that route?

 

Pump

Pump would be my guess, I don't think both caps would fail at the same time, and those caps have metal in them to prevent swelling. maybe the pump was plugged up and then let loose causing suction in the caps.

Eco is not for Ecological as everyone thinks, it is for Economical.

Gino,

Over the years I have read many posts with similar stories about cartridges draining over night, and I know loosing all that ink and making a big mess is no fun.

I know you have a Roland, but here is a post that describes how Mutoh recommends handling the situation, they put out a Technical Bulletin about this issue.

Please post your solution when you get it figured out.
