Internally-heated external rollers transfer heat rapidly to a fuser roller in an electrostatographic printer. Stored media process set points, input image content and input media type data are used to regulate the heat transfer rate by varying the nip width between the heated external rollers and the fuser roller. The rate of heat transfer and the rate of heat transfer adjustment are sufficiently rapid that many different media weights and types may be mixed in a print run without restrictions on media run lengths, without collation requirements per run, and without productivity losses due to slowing of feed rate for heavier receivers.

Roller fuser system with fusing member temperature control for printing

A fuser control system and method are provided for improving the image control of printing systems, including digital front-end processors, color printers and post-finishing system. This automatic image control system, including measurement and calibration, by registering the thermal load measurements.

System for control of fusing member temperature

A radiation unit for a fixation device for fixation of toner material on a printing stock surface for an electrophotographic printing machine, as well as a method for exposure and fixation of toner material on a printing stock surface. Exposure for fixation of toner material occurs essentially indirectly, i.e., the light emitted by the radiation unit is reflected at least once, so that high uniformity and homogeneity of the radiation, efficient energy utilization and avoidance of adverse changes on the printing stock are achieved. A high-energy density, low housing dimensions and independence of the radiation from the employed printing unit are achieved by the fact that the radiation wavelength lies essentially in the ultraviolet spectral range.
