Abstract
A stencil printer of the present invention includes a print drum, an ink feeding device for feeding ink to the inside periphery of the print drum, an ink replenishing device for replenishing ink to the ink feeding device, and a controller configured to control, based on print conditions, replenishment of the ink to the ink feeding device effected by the ink replenishing device. The stencil printer with this configuration is capable of continuously operating even when the ink stored therein is degenerated.

A stencil printer comprising:
- a print drum;
- an ink roller for feeding ink to an inside periphery of said print drum;
- a doctor roller for feeding a preselected amount of ink to an outside periphery of said ink roller;
- ink sensing means for sensing an amount of ink present in an ink well formed between said ink roller and said doctor roller;
- ink replenishing means for replenishing ink to the ink well in accordance with an output of said ink sensing means;
- and
- control means for controlling, when a sense replenishment interval determined in accordance with the output of said ink sensing means varies by more than a preselected amount inclusive due to repeated printing, said ink replenishing means such that said ink replenishing means replenishes ink at an initial sense replenishment interval.
