The Casio DR-210TM printing calculator uses thermal printing, so it does not use or require a ribbon. The calculator prints directly onto thermal receipt paper, which reacts to heat from the print head.
If printing becomes faint or stops printing, the usual causes are:
Replace the thermal paper roll with a new roll.
Make sure the paper is installed correctly with the thermal side facing the print head.
Check that the print head area is clean.
