ABSTRACT:
According to aspects of the embodiments there is provided a cassette cleaning web having an agent metering tube that can apply oil via a drip pipe to a web as it enters a nip within the fusing surface. Dispensing the oil as it enters the nip increases the transportation and the holding capacity of the web. The cassette cleaning web can reduce the oil-on-copy to less than 3 mg/copy and more specifically to less than 1 mg/copy which would allow for adequate post finishing applications while still using amino functionalized fuser oil in the fuser subsystem. The cassette cleaning web reduces the contamination of the oil-sump because used web materials are wound up and oil or contaminate materials like wax, toner are retained in the spent web cartridge. This invention enables reduced oil-on-copy, eliminates the bulky and expensive release agent management system, and also provides a direct cleaning to the surface of the fuser roll.
