In an ink jet system printer of the charge amplitude controlling type, it is required to ensure stable printing that viscosity and surface tension of ink liquid supplied to a nozzle is maintained at a constant value. To this end, there is provided an ink liquid warmer in an ink supply system. The viscosity and surface tension of the ink liquid is maintained at a constant value by holding the ink liquid at a predetermined temperature.

DETAILED DESCRIPTION Accordingly, an object of the present invention is to provide an ink jet system printer which ensures stable printing.
Another object of the present invention is to provide an ink liquid supply system for use in an ink jet system printer which holds the viscosity and surface tension of the ink liquid at a constant value.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
To achieve the above objectives, the ink jet system printer of the present invention is provided with an ink liquid warmer in the ink supply system.
The ink liquid to be supplied to the nozzle is warmed and held at a predetermined temperature, and hence the viscosity and surface tension of the ink liquid are maintained at a predetermined value in order to ensure stable printing.
