Canon HB1-4673-000 is a cassette separation pad for the Canon Fax L-350 and L-360. This part is identified by its exact Canon part number and listed for use in the cassette of these fax machines.
The pad is a paper-feed component that helps separate sheets as paper is drawn from the cassette. It is intended for the cassette assembly, rather than being a complete cassette or a general-purpose printer accessory. Its practical role is to support sheet feeding in the specified fax models.
