Abstract

An arrangement is described which causes a printer to indicate when there is only enough ribbon left to print one page. The end of ribbon sensing function of the printer is replaced by a "almost out of ribbon" function by adding a detection means, such as a piece of adhesive tape, etc., to the ribbon far enough from the end so that ink for one more page of print still exists on the ribbon.

Printer With One Page End of Ribbon Warning

An arrangement is described which causes a printer to indicate when there is only enough ribbon left to print one page. The end of ribbon sensing function of the printer is replaced by a "almost out of ribbon" function by adding a detection means, such as a piece of adhesive tape, etc., to the ribbon far enough from the end so that ink for one more page of print still exists on the ribbon.

When the ribbon senses the "almost out of ribbon" or "last page" marker, an internal flag is set and printing resumes. When an "eject" command or "move to next page" if a tractor paper feed mechanism is attached is received from the system, the printer recognizes the flag, ejects the page, and notifies the system of an out of ribbon condition. The sheet of paper has been completed and ejected, thus greatly simplifying both the human factors and the mechanical requirements for exit tray removal since the partially completed page is not left hanging in the exit path, inhibiting tray removal and ribbon in a ribbon change.
