Abstract
An ink-supply system for a dot matrix printer including an ink-supply tank formed with an ink-supply delivery port and an ink absorbing member formed of a porous material and dimensioned to substantially fill the ink-supply tank. The ink-supply tank includes an inner wall surface having projections to provide a space between the ink absorbing member and the wall surface.
Claims28
A dot matrix printer, comprising:
- printing means for applying ink in a dot matrix to effect printing;
- and
- an ink supply means for delivering ink to said printing means comprising:
- an ink-supply tank;
- an ink absorbing member formed of a porous material and dimensioned to substantially fill the ink-supply tank said ink absorbing member being filled with ink substantially to the desired capacity of the ink-supply tank, said ink-supply tank including an inner wall surface having projections to provide a space between said ink absorbing member and said wall surface;
- and
- means projecting into said ink-supply tank for receiving and transmitting ink from said ink absorbing member for delivery to said printing means.
An ink-supply system for a dot matrix printer head, comprising:
- an ink-supply tank;
- an ink absorbing member formed of a porous material and dimensioned to substantially fill the ink-supply tank said ink-supply tank including an inner wall surface having projections to provide a space between said ink absorbing member and said wall surface;
- and
- means projecting into said ink-supply tank for receiving and transmitting ink from said ink absorbing member for delivery to said printer head.
A dot matrix printer comprising:
- printing means for applying ink in a dot matrix to effect printing;
- and
- an ink supply means for delivering ink to said printing means comprising:
- an ink-supply tank formed with an ink-supply delivery port;
- and
- an ink absorbing member formed of a porous material and dimensioned to substantially fill the ink-supply tank, said ink-supply tank including an inner wall surface having projections to provide a space between said ink absorbing member and said wall surface.
An ink-supply system for a dot matrix printer comprising:
- an ink-supply tank formed with an ink-supply delivery port;
- and
- an ink absorbing member formed of a porous material and dimensioned to substantially fill the ink-supply tank, said ink absorbing member being filled with ink substantially to the desired capacity of the ink-supply tank, said ink-supply tank including an inner wall surface having projections to provide a space between said ink absorbing member and said wall surface.
A method of supplying ink to a dot matrix printer comprising:
- providing an ink absorbing member formed of a porous material within an ink-supply tank having an ink-supply delivery port so that the ink absorbing member substantially fills the ink-supply tank;
- filling the ink absorbing member with an amount of ink constituting substantially the desired capacity of the ink-supply tank;
- providing a space between the ink absorbing member and a wall of the ink-supply tank;
- and
- providing ambient air to the space between said ink absorbing member and said wall.
