Apparatus for controlling the application of fuser release material in roller fusers

摘要

Apparatus for controlling the application of fuser release material such as fuser oil to a roller fuser in an electrographic copier. The number of fixable images or the number of photoconductor frames are counted after the start of a copy run and compared with the number of copies which exit from the copier to determine if the two counts bear a preselected numerical relationship to each other. If they do, fuser oil is applied to the roller fuser; if they do not, application of fuser oil is discontinued until the two counts bear such numerical relationship.
