Title:

METHOD AND SYSTEM FOR CONTROLLING THERMAL HEAD AND STENCIL PAPER ROLL

Document Type and Number:

WIPO Patent Application WO/2004/062914

Kind Code:

A1

Abstract:

A method for controlling thermal energy of a thermal head depending on the surface state of a stencil paper in a thermal head controller controlling thermal energy of the thermal head for punching a stencil paper fed out from a stencil paper roll. Residual quantity of the stencil paper M of a stencil paper roll (21b) is calculated by a means (65) for calculating the residual quantity, the time elapsed after production of the stencil paper roll is acquired based on the data of production date stored in the storage section (70) of the stencil paper roll (21b), data of the type of stencil paper stored at the storage section (70) is also acquired, thermal energy is then determined based on the residual quantity, the elapsed interval and the type data and thermal operation of the thermal head (22) is controlled based on the thermal energy.
