Homebrew PCBs

This printer is much much worse off than I thought.  :(

(totally unnecessary HUGE detailed step by step report removed from here)

Bottom line, I have totally removed the cleaning cart and exposed the vacuum
tube from where it disappeared in my pic, all the way to the cleaning cart.
It is full of semi-liquid black goo.  A short smaller diameter tube leading
to the base of the cleaning cart seems totally gooped up.

I going to try to de-goop the short tube, and see if I can turn to a more
liquid state the section that leads to what looks like a small vacuum pump.
I can only assume the pump will work better if the liquid is thinner.

So I have no vacuum to speak of during the cleaning process, that can't be a
good thing.  I'd be really surprised if I can re-assemble this printer at
this point.  I didn't break anything, but the process of clipping back those
2 springs under the cleaning cart has since been added to the next Olympics
in China.

But I already had a backup plan, I have a brand new CX3810 with unopened
cartridges being shipped to me today.

No. The head slides over to the right, as it does the park pad travels the
last cm with it and rises up to meet the head. It is not violent at all.

After a few cycles of this, you should expect to start noticing that the
park pad looks lighter and nearly dry. Don't touch it with anything with
fibers! It is not really a soft sponge, it is a hard plastic foam that will
snag. So much as a carpet fiber or nearly invisible cat hair laid across the
park pad rubber seal will cause ink wicking and drying.

That's the point.

Over time, paper sheds a very fine dust that, along with normal room dust,
mixes with the splattered ink into a thick mud.

There is also a rubber wiper just to the left of the park pads (see Robert's
pictures) that will also need to be cleaned. It wipes across the bottom of
the print head, if it is gunked up then it's like cleaning a window with a
dirty rag.
