Pro-100 Magenta tanks dripping?

[Grazer5]

Hello. I'm running PC Inks on 9 Pro-100's and i'm starting to run into a problem with the magenta tanks dripping, which causes a big problem with the yellow and photo cyan tanks. It started to happen after about 3 or 4 refills. The sponges look really dark so I'm thinking that they're over saturated. Would a cleaning of these tanks bring them back to normal? BTW, I'm using the drill and plug method. Thanks.

To prevent oversaturating sponges, use the german durchstich refill method: no leaking, no plugs needed and automatically saturation equilibrium obtained after refill, so no oversaturated sponges.

Now that you’re using the top fill method you need to stop the leaking issue first, so even if you wanted to use the German method you can’t till you fix this leak because the cartridge will continue to leak which ever method you use.

When you refill the reservoir it should be filled to 75% full, there’s no need to fill the cartridge to the very top and then when you seal the refill hole it must be 100% air tight 99% won’t do, the leaking is a direct result of you not sealing this refill properly.

Fix that and everything will be back to normal again..

Hi Pharmacist: Where does one go to learn "german durchstich refill method"?

Hi Thombar,

Have a look here (the CLi-42 are very similar to the BCI-6/CLI-8 cartridges):

Take note of how to use the air vent to control how much ink gets absorbed into the sponge.

Thanks so much for those videos mikling. I guess I have to flush a bunch of carts now The German method appears to be kinda time consuming, and when we're running a big job we can go through some colours every 30 prints. Multipy that by 8 and you'll see what I'm up against. Also I think I may have drilled some of the holes out too much thereby causing air leaks. Hot glue for those ones!

How do you guys dry out a cart after flushing? I seen a video of a guy using a pump type garden sprayer to flush from the ink coupler with a storage clip and he said in the comments that he just uses the same setup with no water to drive the water out. It looked pretty nifty, especially for a large volume of carts.

Drill hole is only first time: afterwards refilling is strikingly fast. You don't seal the refill hole at all, no ink is leaking out.

Dry out by rolling end of paper towel up and place against the outlet. Now keep it there with an elastic band.
To dry quickly, place in the sun or someplace with a breeze to dry out the paper towel. use a dehydrator if you have one.
If it is simply a matter of too much ink a couple head cleans will pull out enough to stop the drip. If it is an air leak, you have to get a perfect seal, so will need to reseal and retry with a carefully made hole. Had you removed the ball, and used a 5/32" drill, it will "never" leak.

Oh, I used a 5/32" drill bit. I found the plugs too hard to push in so I reamed them a bit, obviously too much on some. I need to find a really proper bit as well. Spiral flute bits are supposed to work well with plastics.
