Homebrew PCBs

Update on the situation:

The black cartridge registers as totally empty, both using the Epson utility
and that Russian SSC utility.

No more black is getting on the paper, BUT, the cartidge continues to 'wet'
that plastic injector at the bottom of the chariot.  Everytime I remove the
cartridge, that stub is very wet, much more so than blue, and blue prints
nicely.

So I know I have black ink, this is much more than a matter of cleaning the
print heads from the bottom.  I believe I should clean them more
'aggressively' by the top.  It's not a matter of ink having a hard time
getting out, it's a matter of ink not getting in at all.  This is where I
need advice from experienced players.

1. Can I just dap a drop of IPA 99% onto that stub?

2. How is that ink fed into that stub, gravity?

3. Can I use light air spray to increase penetration?

I looked around at removing that chariot for a complete soak, and that
doesn't look like an option.

Ok, I've found only one thing that could remotely look like a vacuum tube.
Night is falling and it's difficult to light the guts of a printer properly,
so I've used what I could and left the images in large format for better
clarity.

This is from the front of the printer, looking where the chariot normally
resides.  I powered on the printer and shut it off while the chariot was
taking a stroll to the left.

That is taken from the back side of the printer.

And that one follows the tube towards the rear of the printer.  It goes
under that white felt pad.

At this juncture (<--- I always wanted to use that word) I'm scared to tug
at that tube.  It appears to be snug in its position.  I don't know how to
easily get clear access to that cylinder where it is attached at the front,
and I'm scared to mess up that rear pad as well.

Resuming trying to clean the head, I have exactly the types of wipes
mentionned on that site...

Do not despair, check the vacuum tubing first of all, if it is well seated  
and not clogged.

...

Everything you do will help me greatly because this model is a likely  
candidate for me. If you are not able to clean the head i would not want  
to risk the same problem, so thanks for giving it your best effort.
