Abstract
A stripping mechanism for removing copy paper from a heated fuser roll includes a first pair of stripping pawls spaced a first distance suitable for optimally stripping copy paper of a first size and a second pair of stripping pawls supported independently from the first pair and spaced a second distance suitable for optimally stripping copy paper of a second size. The first and second pairs of pawls contact the fuser roll at different locations along the circumference thereof.
Claims1
In a contact heat fixing device including a heated roll for use in electrophotographic copying apparatus, stripping mechanism for stripping copy paper from a heated fuser roll to which the copy paper tends to adhere by virtue of tacky toner material forming images on the copy paper;
- said stripping apparatus comprising:
- a first set of stripping pawls supported in contact with said heated roll, said first set of stripping pawls being spaced apart a first predetermined distance suitable for optimally stripping copy paper of a first size;
- a second set of stripping pawls supported in contact with said heated roll, said second set of stripping pawls being spaced apart a second predetermined distance suitable for optimally stripping copy of a second size different from said first size;
- said first set of stripping pawls being formed integrally to a support plate mounted for pivotal movement relative to said heated roll and said second set of stripping pawls being pivotably supported independently of said first set of stripping pawls for engagement with said heated fuser roll;
- and
- said first and second sets of stripping pawls contacting said heated fuser roll at different locations along the circumference thereof.
