Abstract

A resistive ribbon printer with an off carrier ribbon automatically goes to a special ribbon load mode upon an end of ribbon detect. This releases the ribbon, and a message appears on a display informing an operator to load a new ribbon and the keys to press to continue operation. After loading, electronics verify that the ribbon has been correctly loaded and return the printer to the ribbon load position with a special message on the display when a problem occurs. A special end of ribbon verification mode prevents inadvertent entry into the end of ribbon mode. When an end of a ribbon is detected, a printer automatically goes into a ribbon load mode in which its carrier is moved to a special position which releases the ribbon from the mechanism and positions the mechanism so that the ribbon load path is fairly straight.
