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.
