Abstract: A tape cartridge for a debossing stamper includes a casing, a tape-containing supply spool and a tape take-up spool in the casing, the supply spool having at least one reflector pad visually accessible from the exterior of the casing by an optical reflective sensor for detecting and indicating an amount of tape remaining on the supply spool. In one embodiment the at least one reflector pad is a series of equally spaced reflector pads on an outer periphery of the supply spool. The sensor provides a feedback on each 1/4 revolution of said supply reel, the feedback being received by firmware to track the number of motor steps to drive the take-up spool and to rotate the supply spool a 1/4 turn, and wherein a computer calculates the amount of tape remaining on the supply spool based on supply spool core diameter, take-up spool core diameter and total tape length.

Abstract: A dual station hot debossing stamper for a report or book cover includes a print engine having a character finger daisy wheel forcer and a logo die forcer which are actuatable independently by a common servo motor through respective gear trains. A heat and pressure transferable foil tape character cartridge and print wheel are inserted and locked into the engine in a character debossment operation with a motor driving the print wheel. Removal of the character cartridge and insertion of a logo transfer tape cartridge shifts the gears in the print engine. The tape of the character cartridge used with the print daisy wheel has a narrower tape width than that of the logo cartridge. Each of the tape cartridges includes an anti-back rotation spring attached to a reel in the cartridge and may include an adjustable tape advance and indicating means for determining the remaining length of tape on a supply reel. A method of loading heat and force transferable material-containing tape into the cartridges is disclosed.
