A further modification beyond thickness would be removing the "pizza"
wheels. There is a row of thin toothed wheels, they may poke holes in
the ink.
The best mod to them, since they eject the paper right at the end,
would probably be to remove (or raise) all but the wheels along the
edge of the paper path.
I'm anxiously waiting to find out what kind of ink. It may simply be
that his preparation is what did it, rather than the ink, but until we
know what kind it was....
