Abstract

An approach is provided for applying a release agent to a substrate having at least a first surface and a second surface. The approach involves determining a print job type for applying one or more printed images to the substrate to be one of a simplex print job type that applies the one or more printed images to one of the first surface and the second surface and a duplex print job type that applies the one or more printed images to the first surface and the second surface. The approach also involves processing the determined print job type to cause, at least in part, a determination of a release agent application instruction that corresponds with the determined print job type. The approach further involves causing, at least in part, an amount of the release agent to be applied to the substrate based on the release agent application instruction.

Dependent claims

A method for applying a release agent to a substrate processed by a fuser unit comprising at least a first roller and a second roller, the substrate having at least a first surface associated with the first roller and a second surface associated with the second roller, the method comprising:

determining a print job type for applying one or more printed images to the substrate to be one of a simplex print job type that applies the one or more printed images to one of the first surface and the second surface and a duplex print job type that applies the one or more printed images to the first surface and the second surface;
processing the determined print job type to cause, at least in part, a determination of a release agent application instruction that corresponds with the determined print job type;
and
causing, at least in part, an amount of the release agent to be applied to the substrate based, at least in part, on the release agent application instruction,
wherein a simplex print job type instruction comprises a benchmark release agent application value for the amount of release agent to be applied to the substrate for the simplex print job type,
wherein a duplex print job type instruction comprises a duplex release agent application value that is less than the benchmark release agent application value for the amount of release agent to be applied to the substrate for the duplex print job type;
wherein when the determined print job type is a duplex print job type, further comprising:
causing, at least in part, the amount of release agent applied to the substrate to be such that duplex release agent application value is applied to one of the first surface and the second surface;
and
causing, at least in part, the amount of release agent applied to the other of the first surface and the second surface to be equal to the benchmark release agent application value.

An apparatus useful in printing comprising:

at least one processor;
and
at least one memory including computer program code for one or more programs,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
determine a print job type for applying one or more printed images to a substrate processed by a fuser unit comprising at least a first roller and a second roller, the substrate having at least a first surface associated with the first roller and a second surface associated with the second roller, to be one of a simplex print job type that applies the one or more printed images to one of the first surface and the second surface and a duplex print job type that applies the one or more printed images to the first surface and the second surface;
process the determined print job type to cause, at least in part, a determination of a release agent application instruction that corresponds with the determined print job type;
and
cause, at least in part, an amount of the release agent to be applied to the substrate based, at least in part, on the release agent application instruction,
wherein a simplex print job type instruction comprises a benchmark release agent application value for the amount of release agent to be applied to the substrate for the simplex print job type,
wherein a duplex print job type instruction comprises a duplex release agent application value that is less than the benchmark release agent application value for the amount of release agent to be applied to the substrate for the duplex print job type;
wherein when the determined print job type is a duplex print job type, and the apparatus is further caused to:
cause, at least in part, the amount of release agent applied to the substrate to be such that duplex release agent application value is applied to one of the first surface and the second surface;
and
cause, at least in part, the amount of release agent applied to the other of the first surface and the second surface to be equal to the benchmark release agent application value.
