Abstract:
A
fundamental objective in the development of hot roll fusing subsystems in
electrophotography is to optimize fusing latitude. A broad fusing
latitude, defined by the temperature range between which hot and cold
offsets occur, is a critical factor in achieving a robust printing process
and ensuring the highest possible print quality. With the recent
introduction of a stand-alone, computer controlled hot-roll fusing test
apparatus, developers of toners, toner resins, print media, fuser rollers,
and fusing subsystems and the like now have available to them a highly
flexible tool that greatly enhances productivity and objectivity in
optimizing and characterizing the hot-roll fusing process.The system allows the user to control the process speed (between 1
page per minute and more than 100 ppm), the contact load between rollers
(up to 300 Kg or more), the temperature range (from room temperature to
250 C), and the lubricant film thickness (in the micron or submicron
range).In addition to the
flexibility it affords in controlling the process variables, the modular
design of the system enables the user to change the fuser rollers with
ease and to control heating of the fusing and pressure rollers
independently.The design
considerations and a range of practical application examples of this
system are discussed in thhs paper.
