Claims20
A support of a heater in a fuser, the support comprising:
- two parallel sides and a back side, the three sides forming a U shaped cross section, the cross section having a non-uniform wall thickness in which the two parallel sides have a wall thickness along a majority of a length thereof that is greater than any wall thickness of the back side.
A support of a heater in a fuser, the support comprising:
- two parallel sides and a back side, the three sides forming a U shaped cross section, the cross section having a non-uniform wall thickness;
- and
- an opening in a side, the opening reducing a heat capacity of the support.
A fuser, the fuser comprising:
- a support having two substantially parallel sides extending away from a fusing nip, the two sides being arranged on opposite sides of a heater, the support comprising a first material as a substrate and a second material on a surface of the support, the second material having a lower emissivity than the first material, the second material disposed on an outer surface of the two sides away from the heater.
A fuser comprising:
- a fuser sleeve;
- and
- a support within the fuser sleeve, the support comprising:
- two substantially parallel sides extending away from a nip, and
- a back side connecting the two substantially parallel sides, the three sides each comprising:
- a substrate with a first emissivity, and
- a surface with a second emissivity, wherein the first emissivity is greater than the second emissivity, and
- wherein a wall thickness of the back side is less than a wall thickness of the two substantially parallel sides;
- and
- an insulating material between an outside surface of the support and a fuser sleeve.
