Abstract:
1. A method for printing a Braille element comprising: rotating a drum through at least a first complete revolution; charging the drum during a first part of the first revolution; generating a first control signal from a controller operating in a Braille printing mode; successively applying more than one pulse of light, one on top of the other, to a predetermined spot on the drum in response to the first control signal during a second part of the first revolution; adhering a toner to the predetermined spot during a third part of the first revolution; transferring the toner adhered to the predetermined spot to a first paper during a fourth part of the first revolution; forming at least a portion of the Braille element on the first paper with the toner transferred from the predetermined spot; discharging the drum at a fifth part of the first revolution; fusing the Braille element to the first paper; switching the controller from the Braille printing mode to a sight-read printing mode; generating a second control signal from the controller operating in the sight-read printing mode; forming a sight-read element on a second paper during a second revolution of the drum in response to the second control signal; and fusing the sight-read element to the second paper.
