Jinhao 51A Leak - From Opening Too Fast?

[crossstick]

Just got an EF Jinhao 51A. Day 3 with it. Section had surprise ink on it 3 times today when I'm in the process of writing, capping, thinking, uncapping and writing more.

 

Is it me uncapping too fast causing ink to suck out? Seems odd if so because the ink is on the 'grip' of the section and no excess on the nib or feed. I dry out the inner cap each time with minimal ink found there.

 

The pen is laying on a table or in my pocket in a felt sleeve. Not doing anything vigorous with pen on person.

 

No visible cracks or deformities. (In the pen or user.) (As far as you know.)

 

Thanks all !

Not sure whether that's the cause in this case, but indeed the issue of sucking out the ink by rapid uncapping is common with Parker 51 based pens. Happens sometimes even with the actual 51.

 

But that usually shows by drops of ink dripping from the nib, not really ink on the section.

yes these hooded nib and as well any fountain pen ( especially those with slip on type cap ) can had ink simply sucked out by the rapid removal of cap , and the 51A being a fairly wet pen ( compared to other of its peers ) can be even duly so .. try cap it with a clean section and uncap gently and see if the problem persist, if it do then it might be ink creep ( which mean you might want to check if the nib is fitting a bit not tight enough or if the converter fit snug and tight )

Thanks for the input. I need to have ideas and inspiration much slower when using the 51A ! The issue does not seem to happen when I slowly uncap.

 

Maybe if one caps with the force equal to uncapping it would be a net 0 effect?

Well, an update. Was writing with the pen last night and saw a drop of ink forming when I paused with the pen held near the paper. Pen was 80% full of ink. I turned the pen upright and eliminated the air bubble from the converter and resumed use.

 

If there is new advice it would be appreciated. Is that the proverbial 'burp'? I thought burping was more likely with low ink?

 

This was the first of my 9 pens to leak ink out during writing.

If it's happening then, there are a couple of possibilities.

1) Poor seal at convertor.

2) Leaking Convertor

3) Air leak between hood and connector

4) Cracked connector.

 

If it's none of these, it's a feature of the pen.

If it's none of these, it's a feature of the pen.

 

 

A la Microsoft. "It isn't a bug, it's a feature !"

 

EDIT/UPDATE: Everything is seated properly and there are no cracks in this new pen. I've asked the seller for consideration on replacement.

I've had this happen when the converter wasn't properly situated in the section. In one case I just had to apply more pressure. In another I swapped the converter.

[crossstick]

Closing the loop. Returned, reordered and all is well. Nothing would stop the original pen from leaking. Had nothing to do with how the cap was removed.

 

The new one has no problems with all forms of pocket carry in all orientations. (no pun)

Love my 51As. Glad you have another one that works right.
