I heard at a conference that the black goo in the drain lines makes an
     excellent Gram stain + and - control. Even better than Slim Jims...

You may want to check the draining tubes that leads to and from the water
bath.
Scum does have to tendency to build up which would result in the black junk
you
are seeing.  They should be cleaned with bleach.

Recently we have been getting black junk on our slides. We use a Sakura 601
automatic stainer. We stain about 600 slides a day. It does not seem to be on
the tissue just around it. We change our hematoxylin three times a week and
chang all other solutions daily. We do recycle the xylene. We use tap water
in our baths. If you have any suggestions Please help.
