  • Reprography

DEF

An electrostatic charging device, usually composed of a taut wire, which charges a photoconductor to facilitate imaging in the printing process.

CONT

Three types of corotrons, or coronas, are generally employed in a photoconductor imaging system: Charge Corotron, which charges the surface of the drum positively, preparing it to attach negatively charged toner particles; Transfer Corotron, which carries a much higher positive charge than the drum and causes toner to be transferred to the surface of the copy paper and Clean Corotron, which emits a negative charge to neutralize the drum charge and prepare it for cleaning.

DEF

Dispositif de charge électrostatique constitué généralement d'un fil tendu qui charge un photoconducteur facilitant la reproduction d'images dans les opérations d'impression.

CONT

On a généralement recours à trois types de coronas dans les systèmes de reproduction à photoconducteur : les coronas de charge, qui chargent positivement la surface du tambour le préparant à recevoir des particules de toner chargées négativement; les coronas de transfert qui portent une charge positive beaucoup plus élevée que le tambour et qui provoque le transfert du toner à la surface de la copie papier; et les coronas de préparation au nettoyage qui émettent une charge négative servant à neutraliser celle du tambour et à préparer le nettoyage de ce dernier.
