You don’t need “backround={…}”, it’s a leftover from a earlier attempt to find a nice solution to your problem.

\startTEXpage … \stopTEXpage produce a separate page for it’s content where the page is a large as the content itself, try:
\starttext
\input knuth\par
\startTEXpage[width=10cm]
\input knuth\par
\stopTEXpage
\input knuth\par
\stoptext
