[Et tu, line-eater?]

The problem cannot be fixed all that easily.  The problem is that the Ricoh
engine is a WHITE writing engine, not a black writing engine like the Canon.
This means that it assumes the initial page is black and it carves out the
white regions by drawing white pixels on the page.  Dark black solid areas
come out nicer, but characters get that ragged edge look.

A side note - QMS marketed a RICOH-based laser printer up until
very recently.  The engine couldn't be fixed, so they dumped the product
(it was the QMS 1500, for those of you who are interested).
