摘要： An ink jet printing apparatus is described having facilities for printing information in character locations, (boxes) each character location comprising a plurality of vertical columns of drop locations, and a number of characters comprising a line of information. Structures and circuits are included for insuring correct location of information within the character boxes and also providing for one mode in which characters are printed continuously line-by-line and another mode in which characters are printed incrementally character-by-character. During incremental printing, as well as the first character in a line or group of characters, provision is made for re-bounding the printhead back into the box of the character just printed, that is, prior to the next character box to be printed to insure that when the printhead starts up again for the next character that all drop components for that character, including any located in the immediate vicinity of the character boundary, are properly placed during printing.

摘要： The present case concerns various techniques for increasing the printing rate of an ink jet printing apparatus. As one example, drops not required for printing, that is, drop intervals, are skipped. This reduces the time required to form individual characters. Another technique modifies the normal generation of drops which is sequential in a column by column fashion and instead imposes non-sequential drop generation and deflection thereby reducing drop merging and splatter that otherwise might occur.

摘要： Individual ink droplets are formed at a nozzle, propelled toward a record medium, variably charged by a charge electrode, and deflected by deflection plates for printing of characters. Droplets not required for printing are directed to a first gutter. The charges on the droplets develop a current in the first gutter that is sensed in an electronic feedback loop for synchronization of drop formation with drop charging. An auxiliary gutter is positioned to receive drops during a checking interval when a relatively high charge is applied to the unused drops. The relatively high charge on the drops develops a much larger current in the auxiliary gutter that is easier to detect. If desired, synchronization can also be effected by using the auxiliary gutter.
