Digital BW, The Print

Ben,

What I've occasionally had is a black line that is caused by "junk" (dried
pigs, I assume) on the head deflecting one or more jets off to the side.  I
have always been able to cure this by cleaning the head with Windex that is
on a folded paper towel or, best, a 1/2 inch strip of bias tape (available
in the sewing sections of many stores, including Wal-Mart).  (I'm looking at
a package of Wrights Single Fold 1/2" bias tape.)  Before I had the bias
tape, I'd cut and fold a paper towel to about 1/2 inch. 

I soak the tape with Windex, turn off the printer, release the head by
rotating the white gear at the left toward me, raise the head (for thick
paper), lay the soaked tape in the channel over which the head travels, move
the head over the tape, lower the head, grab ends of the tape, and pull it
back and forth across the head.  Then, of course, put the head back in its
place the move the gear back to lock the head.

This should knock and pigment build-up off the surface of the head.

I also rinse the parking pads periodically with windex or "UC base" (4 parts
H2O to 3 parts glycerin. MIS may sell this as "UC base."  I mixed it for
diluting UC inks.  It has no binder in it, but the water and glycerin -- an
excellent dispersant and humicant -- will clean the sponge nicely.  I also
use the UC base for printer storage.  No binder or pigs should mean no
clogging.) 

Once I've cleaned the heads and pads, one cleaning cycle usually has
resulted in the errant line disappearing.

Good luck.
