Try the test you described except hold down the Paper Eject button
instead of the Print Quality button. My working IW II also turns on the
error light when I try the test you described.  The test that is started
by  using the Paper Eject button is the standard test I use to check out
IW II's.  If it prints okay, then I would suspect the cable. Once
however, I had a bad connection at the cable connector inside the
printer.  A wire was pinched by the leg assembly and eventually
separated. Under that condition, the self test worked fine but the
printer would not print properly until I fixed the broken wire.
