Hooking up Dampers - Please Help

2231 Views 16 Replies 5 Participants Last post by  uktech
I purchased a used kiosk that is using carts instead of dampers. Based on a lot of research here, I've decided it is best to convert the white lines to a single bagged Belquette PrintsRite System. I purchased enhanced dampers and plan to leave the CMYK on carts. The current set-up has the equipment Zone Bulk System.

So, the best I can tell, I should purchase the Belquette basic conversion kit to hook-up to the bag. I also would like to change the current ink lines with new so I will need enough Tygon 3/32" R-3603 to go from the one line to the white dampers. Beyond that, I'm not sure what I need? I'm assuming there are barbed Luer adapters (male/male?) to connect the Belquette line to the other lines? What will I need to connect the Tygon line to the dampers? Could someone post pictures of what I need?

Any help would be greatly appreciated!

Adam,

It would probably be a good idea to contact Belquette directly about the conversion. I would also suggest that you do some research into the Epson 2100/2200 that the Kiosk & T-Jet printers were based on - Epson stopped making parts for those machines in August of 2012. Most distributors are already out of print heads and the ones that do have them have been reserving them for current customers who bought their machines directly from them. I would hate to see you pour money into a machine to find it unusable in a few months or so.

Hi Don,

Thanks for the reply. I have three lightly used - but excellent printing - Epson 2200 printers sitting here for parts. Hopefully, the parts from those printers will last me until I can buy something newer.

Which, is why I'm looking to convert to the bagged system, so I will extend the life of the heads.

Thanks,

Adam
Still no answer. Is there no one who can provide details or pictures?
Still looking for an answer...
I ordered some dampers but they are extremely small. Can someone tell me the size of the enhanced dampers used in the Kiosk? These things are half the size of a regular ink carts. Is that how small they should be?
Wow I can't believe nobody saw this, ok there are 2 dampers in the market, they can hookup to the ink lines fine but the hole that the damper has (part where the head connects should be bigger on one of the dampers) Yes they are that small
Thanks DTGPRINTERPARTS! I was surprised they were so small. I didn't expect them to be the size of a cart, but I thought they would be longer to provide more stability. So the only thing that holds them in place is the connection to the head manifold? These fit on the head manifold, but I couldn't tell if it was all the way down. What do I use to connect the damper to the Tygon line? As you can see in the picture, it has a female connection where the line connects. Is there some type of compression nut the slips on the Tygon line and then screws down on the damper?
Yes the manifold should hold it down, ok on the line, you need an O-RING and Nut Screw. If you are thinking about getting the system from Belquette I'm sure that they would be more than happy to help you too. Oh and the only thing that holds the o-ring and screw on is just the tightness and pressure of the ink! How scary is that lol?
Not sure if will help but I have the Equipment Zone bulk ink setup on my Kiosk which uses their ink cartridges which are much larger than the original dampers you show there. I then converted to the bagged ink from Belquette as well. Contact Belquette, they can provide you with all the right connectors you need. I initially got the wrong ones, called them and the right ones showed up a few days later. The bagged ink really does work better...

I also bought the cleaning cartridges from EZ. I leave them in the machine most of the time and only load up the regular cartridges when we need to print. 2 years and no head clogs since I started doing this...

Thanks again DTGPRINTERPARTS.

tfalk, thanks for the reply. I have both the EZ carts and a set of cleaning carts. As I've been reading through the posts on the forum concerning the Kiosk, it appears most have moved away from carts and started using the dampers.

As I've thought about it, since the Kiosk doesn't need a chip, wouldn't a smaller damper be better? I mean, wouldn't a larger cart provide for a greater chance for the ink to spoil in the cart? I know it's impossible, but I'm starting to wonder if it were possible to attach the ink lines directly to the manifold wouldn't that be the best case scenario? Isn't the reason for the cart just a carry over from the printer used to build the DTG that allowed the printer manufacturer to sell ink to the customer? What am I missing?

Honestly, I'm not sure why they ever used dampers instead of cartridges. The problem is usually ink starvation, particularly on the white channels, and that's where the small dampers just can't keep up. I think you would need a pretty small line to connect it direct to the ink bottles. Never thought of that, probably worth a try but I'm sure somewhere someone will come up with a reason that it's not a great idea.

The damper is designed to do 3 things really.

1. It provides a constant balanced supply of ink to the head, as long as the supply of ink to the damper is constant and balanced. Slight positive pressure to the damper seems to be the best way, as is used on many printers (as the head uses the ink the damper refills as required)

2. It has a mesh that filters the ink before it reaches the head.

3. It removes the need for cartridges with limited capacity. Most large format printers use dampers.

I wouldn't advise connecting ink lines directly to the head manifold.Too much ink flow would cause constant dripping from the head, too little will obviously cause ink starvation.
Thanks Uktech. I wasn't aware that the dampers did so much! Do the dampers I have displayed look okay? I ask because you stated that the carts have "limited capacity" but as small as the dampers I have are, it looks like they would be less capacity.
That damper will work fine, but I prefer the larger damper (part No 141 9222) mainly because this is more compatible with the other printers I work with. The damper MAY not fit correctly onto the print head stem as standard, but the "O" rings on the damper are interchangeable (if you are careful)to suit different print heads.
