Pen Exploded?

[Blazing]

Hello everyone.

 

2 days ago, I flushed out my pen out of the Lamy Blue it was using so I could fit in a Diamine Jet Black cartridge. I then filled it up with the Diamine cartridge. It worked well the next day, and I left it overnight yesterday on the table.

 

This morning today, I went to uncap my pen in my first lesson and got a nasty shock. The nib was filled with black ink as if I was refilling it from a bottle and started leaking everywhere. Then I looked at the cap and it had a lot of ink. I unscrewed the grip section to check the cartridge, it was nearly empty.

 

How did this happen?

Spooky... Poltergeist.

Was this your Lamy Safari? They use proprietary cartridges. The Diamine cart went in, but probably didn't fit right.

Every time a Lamy pen sees a standard international cartridge, it gets all cross and does this. I suggest giving the Lamy only its own cartridges or converters.

Pilot MR.

Hm, the MR takes international standard carts. Seating would be the first guess. Check and make sure there are no cracks in the section. Try another cart at home.

[GabrielleDuVent]

My guess is that there's something wrong with the feed. Check if everything is in correctly.

No cracks in the section.

[NedC]

That's the same MR that you had a hard time finding a converter to fit because they were all too loose? I wonder if the nipple on its feed is either out of spec or damaged.

It worked fine with the cartridge which came with the MR.

Hmm ... You might compare the cartridge that came with it against the Diamine cartridge to make sure they are identical. Perhaps you found an unusual version of the MR that takes proprietary Pilot cartridges?

I think the EU MR and US/Asia MR take different cartridges, with one of them only taking Pilot proprietary.

This one takes international standard cartridges as stated by CultPens.

Was there ink anywhere else, i.e. inside the body of the pen?

No, only the water which seemed to be from when I flushed my pen.

Did you keep the pen in a warm place - near a heat vent or an incandescent lamp, etc.? Heat expands ink and also the air pocket inside the cartridge. As the air-bubble expands, it could squeeze ink out of the cartridge. Usually any ink cartridge has sufficient surface tension - in fact, quite enough - so that manufacturers put a small ball inside the cartridge just to break the surface tension (Vanderwall's forces???). Once a drop of ink from the nib contacts the wall of the pen-cap, the cap's inner surface, aided by gravity, would pull the drop - remember how we touch the burette's inside surface with the tip of the pippette to extricate the last drop of liquid?

 

But if physics weren't able to answer this strange phenomenon, then we might have to seek recourse to metaphysics, as follows:

 

Good 'ol Blazing had a pen,

Which was used only now and then.

He fitted it with a cartridge,

Ink not as green as partridge,

But ink as black as tar,

It was not before far,

He went to bed,

My goodness, better less said!

He awoke with a dread,

As he cautiously did tread.

To see if the pen was still asleep,

It was indeed in slumber so deep,

That it became incontinent...

And it was still barely sentient!

It had to pee,

For Blazing to see.

What a nasty mess,

Worth a week's fuss!

Insoucient, ink it puked,

As it also got itself nuked.

Blazing should now keep the pen aside

For, there could be a ghost inside.

Here's what I suspect it is.

 

Check the cartridge for a small crack or that the back end might not have a perfect seal. If the back end has a hole, then the feed will be able to continuously pull ink out of the cartridge to be replaced by air through the back end of the cartridge. The feed will continue to pull ink out through capillary action until no more ink is making contact with the ink.

 

You should be able to test the cartridge by filling the cartridge with water and hold it open end up over a sink and see if any water drips out.

 

Or grab a new cartridge and chuck that one and see if it happens again. If it does its something with how the cartridge is sitting in the feed, maybe the hole on the diamine cartridge is a little too big.
