I have the Janome 6600P. My sewing repair man says all we need to do is use a small paintbrush to remove lint and add one (and only one!) drop of oil to the wick in the center of the bobbin holder. Do not use canned air or blow into your machine. I take it in once a year for a physical.
this machine is a workhorse!
