Abstract

A compact, efficient flash fuser for a copier is shown in Figure 1A. A lamp 2 inside fuser assembly 4 extends across the width of a photoreceptor belt 6. The fuser is designed so that lamp 2 will flash synchrono151y; that is, when developed copy areas 8 pass below and not during passage of intercopy gap 10. A diagram illustrating the required timing is shown in Figure lB.

A compact, efficient flash fuser for a copier is shown in Figure 1A. A lamp 2 inside fuser assembly 4 extends across the width of a photoreceptor belt 6. The fuser is designed so that lamp 2 will flash synchrono151y; that is, when developed copy areas 8 pass below and not during passage of intercopy gap 10. A diagram illustrating the required timing is shown in Figure lB.

The energy source for the flashing is derived from power supply 12 which is subdivided into three independent energy storage sections each of which is charged over a time equal to the full time between copies. With the designs shown, the average power drawn by the fuser is:

where J is the electrical energy in joules required to fuse one copy n is the power supply charging efficiency v is the process speed in inches/see w is the width of the copy in the process direction in inches g is the inter-copy gap in inches (g LO) From the equation it is clear that the average power will remain constant even if the process speed and inter-copy vary as long as the ratio v/g + w is held constant.
