摘要： Apparatus and method for detecting and correcting for evaporation from recirculated unused ink drops in an ink jet printer. The specific gravity of the recirculating ink is compared with that of a standard by measuring the time of fall of heavy floats through reservoirs of circulated and uncirculated fluid. A significant difference in fall times is compensated by the replenishment of fluid in the recirculating ink supply.

摘要： A high pressure fluid source is connected to a primary orifice and a valved orifice of a binarily activated pressure regulator. The primary orifice alone supplies the fluid at a pressure below the minimum desired, and both orifices together supply the fluid at a pressure greater than the maximum desired. A sensor at the output is adjusted to open the binary valve when the minimum pressure is reached, and close the valve when the maximum pressure is reached, thus cycling between the two conditions.

摘要： Electronic lead determining circuitry operates to advantage with nonlinear relative movement between a paper record medium and an ink drop projector carrier of ink drop printing apparatus. Electronic lead determining circuitry is arranged for calculating the proper lead times for displacing the normal print enabling signals by factors dependent on the actual carrier positions and the lead for projecting ink drops at the desired positions.Ink drop printing apparatus of the type having a carrier bearing an ink drop projector across a record medium at a velocity relative to the record medium which may be varying substantially--either by design or unintentionally--, and bearing print position location detecting elements, and bearing ink drop projection controlling elements is perfected by controlling electronic circuitry for calculating lead time at a given print position for enabling printing at a predetermined designated print position precisely at the predetermined desired location on the paper. Preferably, a velocity-time profile for the apparatus is chosen for low g-force loading of the moving components, and printing is effective over most of the profile in contradistinction to conventional printing over linear portions only of conventional profiles. Phase locked oscillator loop circuitry is used for tracking the carrier position and adjusting phase, while several alternate lead calculating circuits are arranged in cooperation therewith. Print position and carrier travel direction data are updated in real time as the apparatus operates under data processing control.
