Abstract

This disclosure relates to a release agent metering device for applying silicone oil or the like to the surface of a fuser roll for fixing toner images to copy substrates. The device comprises a sump 10 containing a quantity 12 of silicone oil. A metering roll 14 is supported for rotation such that it is partially immersed in the silicone oil. A first metering blade 16 is supported in contact with the roll 14 in a position above a second metering blade 18, which is mounted slightly above the static fluid level of the silicone oil, Addi-tionally, by tandem mounting blades 16 and 18 less frequent maintenance is required because there is double the area for toner accumulation. Moreover, by such orientation of these blades the device is less dependent upon a tall curtain of oil, thus allowing a minimum static height which minimizes potential sloshing problems when the machine containing the device is moved about. The blade 18 serves to pre-meter a fixed amount of oil which can subsequently be precision metered to the roll 14 by the first blade 16.

This disclosure relates to a release agent metering device for
applying silicone oil or the like to the surface of a fuser
roll for fixing toner images to copy substrates. The device
comprises a sump 10 containing a quantity 12 of silicone oil.
A metering roll 14 is supported for rotation such that it is
partially immersed in the silicone oil. A first metering
blade 16 is supported in contact with the roll 14 in a position
above a second metering blade 18, which is mounted slightly
above the static fluid level of the silicone oil, Addi~
tionally, by tandem mounting blades 16 and 18 less frequent
maintenance is required because there is double the area for
toner accumulation. Moreover, by such orientation of these
blades the device is less dependent upon a tall curtain of
oil, thus allowing a minimum static height which minimizes
potential sloshing problems when the machine containing the
device is moved about. The blade 18 serves to pre-~meter a
fixed amount of oil which can subsequently be precision
metered to the roll 14 by the first blade 16.
