FUSER RELEASE FLUID RATE TRANSIENT CONTROL VIA VARIABLE SPEED OIL METERING SYSTEM

摘要

An apparatus for applying release agent to a fuser roll used in printing a print job is provided. The apparatus has a release agent metering roll supported for contact with a supply of release agent material; a variable speed drive arranged to effect movement of the release agent metering roll in an endless path at different surface velocities; a donor roll supported in contact with the release agent metering roll and the fuser roll, the donor roll arranged to convey release agent material from the release agent metering roll to the fuser roll at various rates depending on a surface velocity of the release agent metering roll; and a controller that controls a velocity of the variable speed drive such that the surface velocity of the release agent metering roll varies relative to a surface velocity of the fuser roll and the engagement and disengagement times at the start and end of the print job. The variable speed drive is operative independently of the fuser roll.
