An electrophotographic imaging device, comprising:
- a print media transport assembly;
- and
- a fuser positioned in association with said print media transport assembly, said fuser including:
- a first heater assembly;
- a belt positioned around and adjacent to said first heater assembly;
- a backup roll positioned in opposition to said first heater assembly on a side of said belt opposite said first heater assembly, said belt and said backup roll defining a fusing nip therebetween;
- and
- a second heater assembly positioned in association with said backup roll.
A fuser for an electrophotographic imaging device, said fuser comprising:
- a first heater assembly;
- a belt positioned around and adjacent to said first heater assembly;
- a backup roll positioned in opposition to said first heater assembly on a side of said belt opposite said first heater assembly, said belt and said backup roll defining a fusing nip therebetween;
- and
- a second heater assembly positioned in association with said backup roll.
A method of operating a fuser of an electrophotographic imaging device, comprising the steps of:
- transporting a print medium to said fuser;
- carrying the print medium through a fusing nip between a belt and a backup member;
- and
- heating toner particles on the print medium using a first heater assembly positioned on a side of said belt opposite the print medium, and a second heater assembly positioned in association with said backup roll.
