Abstract
A method and apparatus is disclosed to manually re-ink cartridge ribbons for printers, word processors, typewriters and the like. By removing a strategic portion of a top cover of the cartridge which overlies the inking pad or roller residing therein, a specific and measured amount of ink can be dropped onto the pad to effectively re-ink the cartridge. A cover having apertures therethrough to install the ink onto the ink pad or roller is provided. A method of apprising the current ink capacity of a cartridge, by comparing the printing output to a printing key is disclosed.
Claims21
An apparatus for re-inking a ribbon for a printer comprising:
- a housing having a top wall, said housing mounted to said printer;
- an ink pad residing inside said housing, beneath said top wall, said ink pad having a top surface area, said ink pad for holding a capacity of ink;
- roller means for continuously removing an amount of ink from said ink pad and applying said amount of ink onto said ribbon;
- said housing provides at least one opening through said top wall, arranged above said top surface area, said at least one opening comprising an aggregate open area at least 50% of said top surface area of said ink pad, said at least one opening for applying incremental amounts of ink therethrough, onto said ink pad to replenish the pad.

- a piece of paper;
- a first sample of printing on said paper having a first printing weight corresponding to a desired ink capacity of said ink pad;
- a second sample of readable printing on said paper, adjacent to said first sample of printing, having a second printing weight more faint than said first sample and corresponding to an ink level in said ink pad wherein a select additional amount of ink is required to replenish said ink pad to said desired ink capacity;
- wherein said second sample of printing comprises letters selected to form alpha numeric printed indica giving readable instructions to the user as to the amount of ink to be added to the ink pad to replenish the ink pad to said desired ink capacity.

A method for replenishing ink content in a ribbon cartridge for a printer comprising the following steps:
- providing a cartridge having a ribbon carried therein;
- providing an ink pad located within said cartridge and holding a capacity of ink, said ink pad having a top surface area;
- providing a roller means for removing desired quantities of ink from said ink pad and applying said quantities onto said ribbon during use;
- providing at least one opening in said cartridge, said at least one opening arranged overlying said ink pad exposing at least 20% of said top surface area of said ink pad, so that measured quantities of ink may be distributed onto the ink pad from an outside source of ink;
- using the cartridge in the printer, printing a printing output;
- providing a printing guide which displays two printing samples, a first sample corresponding to a printer output wherein a sufficient quantity of ink exists in a hypothetical cartridge, and a second sample of a fainter print corresponding to a cartridge which needs replenishing with ink;
